Once the system has started, pressing the button again will turn it off. If for some reason the
instrument stops responding, pressing and holding the button for a few seconds will turn it off.
The unit is battery operated and the battery should last for between 1.5 and 3 hours dependent on
which video standard is being used and whether the input and outputs are active. If the unit isswitched on and the battery is almost discharged, it will turn itself off. If the battery level becomes too
low for operation a dialog will be displayed prompting the user to turn off the unit. The current settings
will also be saved. The unit should then be connected to the power supply unit as soon as possible torecharge the battery. The battery should be fully charged in about four hours. The battery will charge
faster if the unit is switched off while charging.

Menu Operation
Main Menu
The Main menu, displayed on the TFT LCD screen gives access to the software modules available on
the SxA instrument. The buttons below the screen correspond to the menu areas. Pressing on any ofthese buttons will display the corresponding menu.

The Main Menu provides an overview for the system. It shows the video input and output standards
and frame rate. The audio status for the generator shows which audio groups are being generated
whilst the audio status for the input shows which groups are present and an overview of the channel
status for each audio channel.
Audio channel status is displayed as:l

P if PCM audio is presentl

N if Non-PCM audio is presentl

E if Dolby E packets are presentl

D if Dolby Digital packets are presentl+ if Dolby Plus packets are presentl

V if the validity bit is set

Dolby E program configuration and Timing status is also displayed if the Dolby E analysis option has
been purchased and a Dolby E signal has been detected on the selected input. If the generator isgenerating errors, then the video standard is displayed in red. If the input detects errors, then the
input standard will be displayed in red if the analyzer is monitoring the input.

Page 1-2

PHABRIX SxAUser ManualIf the unit is connected to the network, the current TCP/IP address of the unit is displayed in the
Remote Control box. If the unit is NOT connected to a network and is set to DHCP mode, it will show‘acquiring’ to show that the connection hasn’t been made yet. The model type is displayed at thebottom right corner of the screen.

Instrument Status
The top line of the menus shows the unit status and includes the Input Video status, Genlock status,
battery status and current time. If the unit is being powered by the AC adapter, the battery status icon
will change color to yellow. If a command script is being run, this is shown on the top line to the left of
the time as Script. A red Log label is displayed on the status line if there are any events in the eventlog.
If a 3G video standard is selected the video standard display will be shown as 3GA if it is a 3G-Level A
standard, 3GB if it is a 3G-Level B dual link standard, 3G2 if it is a 3G-level B dual stream (two patterns)
standard or DL if it is a dual link output.
The input video standard will be shown in red if the input signal has errors, but only if the analyzer isconnected to the input. If the analyzer is set to monitor the output, the input standard will be shown inbrown.
The output standard will be shown in red if the instrument is generating errors. The output standard
will show OFF if the generator output is Off.

PHABRIX SxAUser ManualSx Software Options
Overview
The instrument has a range of software options that can enhance its functionality for specificapplications.

AV Delay Analysis (Option: PHSXO-AVD)
The AV Delay Analysis option (PHSXO-AVD) offers an end-to-end solution for the measurement of
the Audio to Video differential delay through a broadcast system, when used in conjunction with the
AV Delay Generator. The analyzer tool provides a real-time update of the differential delay between
the video and the selected audio channel pair. When using the SxA and SxE, this tool can also be
used to measure the propagation or pipeline delay of either video or audio.
Both the AV Delay signal generator and analyzer can be used with all Sx supported video formats
and frame rates on SDI and AES interfaces.

The AV Delay Generator produces an adapted EBU Tech 3305 AV Sync clapperboard Test Pattern.
This is compatible with third party AV delay analyzers such as the LAWO V_pro8.
An audio delay offset with respect to video of up to +/− 40 frames can be applied in increments of one
frame.
The AV Delay audio pulse can be inserted on up to 16 embedded SDI audio channels, plus the AES
out.

PHABRIX SxAUser Manual

Page 1-5

AV Delay measurement (PHSXO-AVD) is available in the Picture instrument. Measurement of two AV
Delay test patterns is supported:l

EBU Tech 3305l

LAWO V_line AV Sync test pattern

The tool provides a real-time update of the differential delay between the video and the selectedaudio channel pair.
The source of the audio can be either an embedded SDI audio or AES channel pair. The differential
delay between the video and the selected audio is measured in 0.1 ms steps (to an accuracy of 1 ms)
with a measurement range of +/− 400 ms.

Advanced Video Formats and 2K (Option: PHSXOF)

This option (PHSXOF) provides advanced formats including: 4:2:2 YUV, 4:4:4 RGB and 4:4:4 YUV at
10/12 bit, and 2K formats including: 4:2:2 YCbCr, 4:4:4 RGB’ and 4:4:4 YCbCr at 10/12 bit as well as
4:4:4 XYZ at 12-bit. For broadcast manufacturers this option allows rigorous testing of many moreformats beyond the standard signals used in traditional broadcasting.
The 2K-SDI support provides analysis of, and test pattern generation for, 2K Digital Cinema as
defined in the SMPTE ST 2048-2:2011 standard 2048 x 1080 Digital Cinematography Production
Image FS/709 Formatting for Serial Digital Interface and SMPTE 428-9 D-Cinema Distribution Master Image Pixel Structure Level 3 - Serial Digital Interface Signal Formatting.
Among the support for 3G Level B on the SxA is the ability to generate and analyze signals such as
SMPTE 425-B carrying 1 x 372M dual link payload.
Uniquely the PHABRIX units create three pathological signals in all formats which will be of greatinterest to broadcast manufacturers. The first is as defined in SMPTE RP198 and is the split field signal
with the equalizer test in the first half and the PLL test in the second half. The second and third areseparate full-frame EQ test and PLL tests signals. To maintain a regular parity distribution and mitigate
any DC offset, the EQ part of the pattern inverts a bit at the start of the first line in each alternate frame.
This is the form of 3G Level B Pathological signal that many video manufacturers are adopting as theirtest signal of choice as it stresses electronic circuits more thoroughly.

Page 1-6

PHABRIX SxAUser ManualCommand Scripts with Print Report (Option: PHSXOS)The Command Script and Reports option (PHSXOS) allows a series of predefined actions to be run
through within the PHABRIX Sx using a script stored in internal memory.
The command scripts option can be used to automatically step through a sequence of instrument
states, controlling the generator, analyzer and logging functions. If required, the instrument willprompt the user before going onto a subsequent state.
Applications include repeated test sequences as required by manufacturer Test Departments,
Research and Development Departments, Systems Integrators and Commissioning/Support
Engineers.
A script requires a set of memories to configure the unit and then a script file which recalls thosememories and specifies times and actions for each step. The process of creating a command script
requires these two files to activate the sequence.
Additionally, a script can be created as a simple text file on a PC and then transferred to the unit overthe network and recalled at any time. Many named scripts and memories may coexist in the
instruments store to be recalled as required.
Access to the Command Scripts functionality is the menu: System → Command Scripts. See thechapter Menu Reference for details.

SDI Data Display and VANC/ANC Inspector (Option: PHSXOSD)The SDI Data Display and VANC/ANC Inspector option (PHSXOSD) provides the engineer with adetailed view of the data words contained within the SDI stream. This allows the analysis of complex
PHABRIX SxAUser Manual

Page 1-7

faults and is particularly useful when determining compatibility issues between equipment and when
debugging new product developments particularly in a research and development environment.
Detail in the active SDI stream can be viewed with continuous update.
The SDI Analysis option provides the following functional areas:
Grid:
Displays the SDI data in the form of an array.
Stream:Allows the SDI continuous data stream to be viewed.
Component:
Allows the video components to be displayed in separate columns.
Split:
Allows the video components to be display individually.
Ancillary Data:
Allows the user to capture whole ancillary data packets identified by their data id (DID).
Ancillary Status:
Allows additional user defined selections with the appropriate DID or SDID code.
Access to the SDI analysis functionality is through the menu Analyzer → Signal Data. See the section
Signal Data for details.
This option also provides a VANC/ANC Inspector - allowing Ancillary data packets to be detected andchecked for errors.

Enhanced Remote Control (Option: PHSXOR)The Enhanced Remote Control Integration option (PHSXOR) gives users full remote control of the unit
through TCP/IP Sockets to allow any aspect of the unit to be modified or queried.
This allows complex applications to be created to perform test and measurement functions such as
automated testing of routers or other broadcast equipment.
PHABRIX products act as a server and listen on a port waiting for incoming requests from clients suchas a PC. Using this method of communication the Sx range can provide a variety of information to the
Page 1-8

PHABRIX SxAUser Manualcontrol device to which it is connected and be controlled in specified areas of the product using thecommand details included. All visual controls on the product have an associated command.
Messages may be sent to SET or GET data from a command. For example, if you SET a value, the unit
will be configured accordingly and a reply returned and if you GET a value from the unit, it will reply
with that value. All messages are acknowledged to increase the security of the interface i.e., using
closed-loop communication.
The control structure can be selected as Passive or Active. Passive control allows simple remotecontrol where the host PC is in control and sends commands when it wants to change data or get
information. It is this method which is the most popular use for remote control.
Active control is when the PHABRIX unit synchronizes with the host PC. Any changes on the PHABRIX
unit will result in a message being sent to the host PC. This method is useful for controlling a PHABRIX
unit from another unit or via the PC simulator software. It requires more complex software on the hostto respond to the returned messages.
The option provides a programming guide with command information and examples, and can be
downloaded from the PHABRIX website. A Windows™ application for testing the interface is also
provided as part of this option.
See the Sx Remote Control Guide for details.

Programmable Zone Plate (Option: PHSXOZ)The Zone Plate Generator option (PHSXOZ) adds a range of preprogrammed zone plate patterns
along with user-defined controls over several parameters which can be saved to custom buffers.
Using the System → Memories menu window, multiple saves of zone plates can be saved to thesystem by checking the video box and saving by name. In use, the zone plate can be used to test arange of video processing requirements using horizontal, vertical and temporal (time) controls.
Temporal control is particularly useful for testing up/down converters and applications which
compress signals.
Aspect ratios can be tested using the horizontal and vertical controls. Frequency sweep is particularly
useful and also available using this option. By feeding in the generated signal, the output of thedevice can be sent back into the waveform monitor of the Sx instrument to determine the usablebandwidth of the system. Once purchased, the zone plate editor is accessed by selecting the button
next to the standard zone plate.

Dolby Bit-stream Analyzer and Generator (Option: PHSXO-DAG)
The Dolby bit-stream analysis and generation option (PHSXO-DAG) displays Dolby E, Dolby Digitaland Dolby Digital Plus metadata present in a selected audio stream and determines whether the
PHABRIX SxAUser Manual

Page 1-9

Dolby E packet is timed correctly on the SDI video stream. It also uniquely adds significant Dolby E,
Dolby Digital, and Dolby Digital Plus metadata generation features to the Sx range.

The Dolby audio may be monitored from any of the SDI input embedded audio channel pairs or the
AES input. Peak audio levels are also displayed for Dolby E.
The start menu window displays both the V Bit information and PCM values along with a snapshot of
the Dolby audio metadata if a Dolby is present. Using the Signal Information - Dolby menu will present
the full analysis display which forms the major analytical tool for this option.
The Dolby metadata screen carries primary information including signal source, Dolby E guard band
timing, CRC errors, program channel and metadata detail. The characters shown in white will only bepresented when a Dolby signal is introduced into the unit.
Peak audio levels included in the Dolby E metadata packet are displayed, allowing the user to selectthe appropriate set of meters to display Dolby levels which will follow the selected Dolby source.
Logging for Dolby errors, Dolby E Timing, Common metadata, and Program metadata can also becontrolled.
Note: This option does not decode Dolby audio

The Dolby generation capability provides broadcast engineers with a highly functional set of tools for
Dolby E, Dolby Digital and Dolby Digital Plus streaming. It is unique in being the world’s first metadata
Dolby generator with editable profiles.
With a selection of Dolby streams to choose from, engineers can quickly enter and adjust parameters
to check broadcast infrastructure.

Page 1-10

PHABRIX SxAUser ManualThis option allows the display of Dolby metadata present in a selected audio stream and determines
whether the Dolby E packet is timed correctly on the SDI video stream.
Dolby streams are provided for all program configurations with fixed audio data. Among the tools
included in the Dolby E streaming option is the ability to adjust the start of frame for Dolby E packets.
The generated Dolby audio follows the video generator reference source. There is also the ability toedit the program configuration and bit depth with fixed audio signal. The PCM stream can be carriedon any embedded or AES pair. The option can set the video line number where the internallygenerated Dolby audio test stream begins. Metadata can be edited by the user and stored inmemories.
The option allows a closed loop test scenario with both generation and analysis toolsets.
Note: This option does not generate Dolby audio.

Ancillary Data Status (Now Included as Standard)

The Ancillary Status option (PHSXOVNC) provides broadcasters, studios, OB and broadcast
manufacturers with a detailed analysis of the ancillary data present in an SDI signal.
A simple grid layout provides a quick check for an engineer of the available VANC/ANC ancillarydata. The packet type is then displayed as present, absent or red if in error. Simple icons next to thepacket indicate the fault. Each ancillary packet available from the grid view can be set to enable
logging and then presented together with other information in the events window of the logging
menu.
This option further allows additional, user-defined selections with the appropriate DID or SDID code.
Any ancillary packet code can be saved down for future recall. Note that this option does not fully
decode the ancillary data, but instead it is used to identify whether the packet is present in the signal.

PHABRIX SxAUser ManualAllows user-defined test patterns that have been created in XYX non-linear color space tobe selected.
The XYZ, X, Y and Z settings in the Waveform monitor display the XYZ color space in its native nonlinear form. So test patterns such as Legal Ramp will be displayed as curves instead of straight lines.
The X'Y'Z', X', Y', and Z' settings in the waveform monitor display the XYZ color space with a reverse
transform to convert it to linear form, so test patterns such as Legal Ramp will be displayed as straightlines.
The Picture monitor and Vectorscope instruments will automatically apply the appropriate transforms
to display the images in YCbCr, RGB and XYZ color spaces correctly. The color space transform to be
applied is defined by the SMPTE 352 payload.

AV Delay Generator

The AV Delay Generator produces an adapted EBU Tech 3305 AV Sync clapperboard Test Pattern.
An audio delay offset with respect to video of up to +/− 40 frames can be applied in increments of one
frame.
The AV Delay test pattern and audio pulse provided by the Generator module can be used tomeasure the differential delay between the video and audio paths in a piece of equipment or an SDI
or AES based system.
In the Video Out menu page, the AV Delay test pattern and Audio Delay offset can be selected.
In the Audio Group menu pages, the AV delay audio pulse can be inserted on up to 16 embedded
SDI audio channels, plus AES out.
When using the SxA, this new tool can also be used to measure the propagation or pipeline delay ofeither video or audio.
Note: The AV Delay signal is compatible with third party AV delay analyzers such as the LAWO
V_pro8.
The AV Delay Generator creates an adapted EBU Tech 3305 AV Sync pattern. This provides aconstantly moving clapperboard which, when it closes, shows a vertical white flash line for one framewith a corresponding audio pulse.
To access the AV Delay Generator option:l

Select A/V Delay in the Pattern dropdown menu
AV Delay can be used with all Sx supported video formats and frame rates on SDI and AES
interfaces.
An Audio Delay field is then displayed.

Using the Audio Delay field, you can offset the timing of the generated audio pulse relative to thecentral white flash frame of the test pattern. An audio delay offset of up to +/− 40 frames can beapplied in increments of one frame. The delay value in milliseconds is displayed alongside the frame
delay value.
lWhen Audio Delay is set to a positive (+) value, the audio pulse will lag the videolWhen Audio Delay is set to a negative (−) value, the audio pulse will be ahead of the video.

The audio delay offset has several applications:
PHABRIX SxAUser Manual

Page 2-7

1. The differential delay of a system or device under test can be quickly measured in TV frames
by adjusting the Audio Delay offset until the measurement reads less than a TV Frame. This canquickly confirm that the differential AV delay is an integer number of TV frames
2. The analyzer can measure AV differential delay up to +/− 400 ms. If the system under test has a
propagation delay longer than this, setting an offset of up to −40 frames extends the overallmeasurement window.
On the AV Delay analyzer, a measured delay amount that is not accounted for by the generated
Audio Delay offset, will indicate delay introduced by the system under test.
To choose the AV Delay pulse audio channels, go to the Generator → Audio Group [1/2] [3/4] menu
pages, and select AV Delay in the dropdown menu for each audio channel as required.

EDH
If the output signal is SD (PAL-625 or NTSC-525) the insertion of EDH information may be switched on
or off.

ErrorsThis field enables the insertion of CRC or EDH errors into the video signal. This allows checking ofthird-party error detection circuitry. In SD, there is one EDH ancillary packet per field. When errors arebeing inserted every EDH value is deliberately corrupted, creating one error count per field or, more
precisely, one AP error and one FF error. In HD, a CRC value is calculated for each line. When errors
are being inserted the CRC value on line number 1 is deliberately corrupted. This creates one CRC
error count per frame. There is also the option to generate CRC errors (not SD EDH errors) on only theswitching line in field 1 which can be used to check that any downstream equipment ignores errors on
switching lines.

SMPTE 352
This checkbox allows the SMPTE 352 Payload ID field to be inserted into the video output stream.
The state of this checkbox is stored separately for SD, HD and HD-3G line standards.
Note: For all HD-3G line standards the Payload ID should be switched on.

Ident
A picture or text Ident may be set to identify an SDI source. This Ident can be switched on or off fromthis page but any changes to the text, font, or bitmap are made in the Ident dialog by selecting theEdit button. An overview of the Ident can be seen beside the Edit button.
Note: If Zone Plate or Color Field patterns are selected, text cannot be overlaid on them.
A thumbnail version of the video output signal is displayed on this page with any overlaid Ident.

Page 2-8

PHABRIX SxAUser Manual

The Edit Generator Ident dialog allows selection of either a user-defined bitmap picture,
downloaded into the Idents directory of the Sx instrument or user-defined text.
For both types, the position of the ident on the screen can be set to one of the following:l

Top-Leftl

Top-Centerl

Top-RightlLeft-CenterlCenter-ScreenlRight CenterlBottom-Leftl

Genlock Menu

The Sx instrument can create video test signals that are either free-running or locked to a studioreference signal.
The Genlock menu is used to select an external locking reference or set the instrument to free run.

Source
The generator may be locked to an input reference which may be either the external reference input
which is a Bi-Level/Tri-Level sync or may be locked to the video input (Input-1). Alternatively, thegenerator may free-run.
If Free-Run is selected, the user can select the Adj Freq checkbox to adjust the frequency of thedatastream by more than + / − 100 ppm. This feature enables the user to generate SDI signals that are
off-frequency to, for example, test the susceptibility of a system to absolute clock frequency. The
adjustable range is from 0 to 1024, with the nominal mid-point at approximately 580. Incrementing thevalue increases the signal frequency and decrementing value decreases the frequency.

Frequency Adjustment

PHABRIX SxAUser ManualDelayThe SDI and AES outputs generated by the unit can be advanced/delayed with respect to thecurrently selected locking reference. Controls are provided for line and pixel advance/delay for SDI
and AES output.

Audio Group Menu

The Sx instrument can embed an audio signal on all 16 embedded audio outputs.
The Audio Group menu controls which audio channels, pairs or groups have test tones applied andthe type of tone.

Group nEach of the four groups may be separately enabled. When enabled, the source and level of eachchannel in a pair can be selected.

PHABRIX SxAUser Manual

Page 2-11

Source
The source for each channel may be Silence, Fixed tone (a range of fixed frequencies), variable tone
(where the frequency can be set on 1 Hz steps from 1 Hz to 23.99 kHz), white noise, or AV Delay. The
AES input may also be selected if present. If the Dolby Generation option has been purchased, thesource may be set to Dolby at which time the other channel in the audio pair is also set to Dolby andgain control is disabled.

AV Delay Audio Pulse
For AV Delay audio pulse generation, choose which audio channel should carry the AV Delay pulse,
and then set the source to AV Delay in the dropdown menu. Make sure that the Group checkbox for
this channel is also enabled.
The AV delay audio pulse can be inserted on up to 16 embedded SDI audio channels and an audio
pair can also be routed to the AES Out.
To route an AV delay audio group pair to AES Out, select the embedded output pair in the AES o/pdropdown menu.
If an Audio Delay offset is required for the generated AV Delay pulse, this can be set in the Generator→ Video Out page after selecting the A/V Delay test pattern. An offset of up to +/− 40 frames can beapplied in increments of one frame.

Inv (Invert)
This checkbox phase-inverts the audio signal to allow checking of third-party audio mixing.

Link
This checkbox links the left and right channels of a pair so that changing the level on the left-handchannel also changes the level on the right-hand channel.

Master
The Master level sets the 0 dB level for all the embedded audio channels, so if the Master level is set
to −18 dB and Group 1 Pair 1 output is set to −2 dB, the actual level output on that pair is −20 dB. Thisfeature allows all embedded outputs to be adjusted together, as well as giving a simple method tochange from −18 dB to −20 dB based standard levels. The Master level will not adjust the level of an
AES input signal selected for embedding on SDI output.

AES O/P
The AES o/p (output) control selects the source for the AES output of the Sx instrument and can be:ll

The AES input (through the built-in sample rate converter) to convert to 48 kHz sample rate AES
signals.
A mirrored output of the specified embedded AES stream contained in the SDI output to generate audio tones or white noise.

lOne of the embedded input pairs on the SDI input to allow use as a de-embedder.

lOff, if the output is not required.

Note that the AES output is always at a 48 kHz sample rate. The AES input includes a sample rate
convertor and so will accept any sample rate between 32 kHz and 192 kHz.

PHABRIX SxAUser ManualDolby (Dolby Generator Option: PHSXO-DAG)

The Sx instrument Dolby Generator software option (PHSXO-DAG) allows the generation of Dolby E,
Dolby Digital and Dolby Digital Plus pre-encoded test signals to check that they are transferredtransparently through the broadcast chain unaffected by routers/switchers, satellite links, etc.
The Audio - Dolby menu controls the generation of Dolby test data.
Note: Note that with this software version non-keyed signals are generated which may be
incompatible with certain VTRs.

Overview
There are several Dolby broadcast digital audio standards that transport audio data over an SMPTE
337M AES carrier with a 48 kHz sample rate. The type of Dolby to be generated can be selected fromthe dropdown list in the top left corner of the menu:l

Dolby El

Dolby Digitall

Dolby Digital Plus

These standards can be used to transport mono, stereo, 5.1 and 7.1 audio programs:
Dolby 5.1:
Involves five channels for normal-range speakers (20 Hz – 20,000 Hz) (right front, center,left front, rear right, rear left) and one channel (20 Hz – 120 Hz allotted audio) for the subwoofer driven low-frequency effects.
Dolby 7.1:
Uses six channels in the primary program (Independent Substream) for a standard 5.1 surround sound mix and then the remaining two channels in an ancillary program (Dependent
Substream) to provide the additional down-mix.

Dolby E
Dolby E is an audio encoding and decoding technology developed by Dolby Laboratories that allows
up to 8 channels of audio (mono, stereo, 5.1 or 7.1) for a primary program (Program 1) and optional
ancillary programs. These eight channels are compressed (lossless) into a digital stream that can be
PHABRIX SxAUser Manual

Page 2-13

transferred between compatible devices and stored on a standard stereo pair of audio tracks. The
most elaborate mode in common use is Dolby 7.1 which uses all eight channels to provide surroundsound.

Dolby Digital
Dolby Digital (AC-3) is a perceptual audio system for digital audio that allows the reduction of dataneeds to deliver high-quality sound. This system was developed primarily for DTV, DVD and HDTV.
This format allows up to six channels of sound (mono, stereo or 5.1) in the form of a single programthat can be delivered at different bit rates. These six channels are compressed (lossy) into a digital
stream that can be broadcast. The most elaborate mode in common use is Dolby 5.1 which uses all six
channels to provide surround sound.

Dolby Digital Plus
Dolby Digital Plus (E-AC-3) is a more advanced version of Dolby Digital that provides a more efficientencoding algorithm offering a primary program and optional ancillary programs. These can be
optionally delivered at lower bit rates than Dolby Digital.

Dolby E Synchronization - Generator Reference
The Dolby audio test signal produced by the Sx instrument is affected by a reference signal
connected to the Sx instrument and by the following settings:
Free Run:
If the generator is not locked to reference, the Dolby signal will be generated synchronous
to the generator. If the generator is running at a fast progressive rate (50 - 60 fps) it will generate packets on every other frame.
External Reference / Ext SDI Reference:
If the generator is locked to an external signal, the reference signal must be of an appropriate standard. See the table below for examples.

Stream type:
Only Dolby E streams can be generated with this software version.
Config, Bit Depth:
The program configuration and Bit Depth can be changed to load the pre-encoded file.
Stream contents:
The tones generated are of a fixed predefined frequency. Four sets of pre-encoded
streams are provided:
Ramp Var:
Each channel has a different frequency to allow checking of channels. The
levels are ramped so that different channels have different levels.
−3dB Fixed:
All the tones are at −3 dB co-phased/timed and are at the same frequency.
−18dB Fixed:
All the tones are at −3 dB co-phased/timed and are at the same frequency.
−20dB Fixed:
All the tones are at −3 dB co-phased/timed and are at the same frequency.

Dolby E Start Line:The start line can be used to set valid or invalid ranges to allow checking of the Dolby E
guard band on downstream equipment. If the start line is set outside the valid range specified by Dolby, the line number will be displayed in red.
Relative to Ideal:
If this checkbox is checked, the line number displayed is relative to the Dolby specified
ideal line. A value of 0 therefore starts the Dolby E packet on the Ideal Line for that video
format.
Frame Rate:
This is set by default to the currently generated frame rate but may be modified by the user
to test downstream equipment.
Original Rate:
This is set by default to the currently generated frame rate but may be modified by the user
to test downstream equipment.

PHABRIX SxAUser Manual

Page 2-15

Note: When generating a progressive fast rate video standard such as 720p50, 720p59 or
720p60 etc., the Dolby E signal will always be generated at the related slower rate. This is a
Dolby restriction as the packets are over one frame in length for these video formats.

Program Metadata Editing
Many of the metadata fields may be edited to test downstream equipment. The Channel Mode field
may be edited to invalid settings but they will be shown in red to show that they are invalid. The
settings currently being edited are for the selected program, but multiple program metadata values
can be modified and the settings for all programs are stored in memories.
Metadata changes and line changes will happen cleanly so that no corruption to the Dolby signal will
occur.
A maximum of 30 characters may be used for program description text. If the text is longer than this,extra characters will be ignored.
The Generator → Dolby menu allows the metadata for a Dolby E datastream to be setup for testing
purposes. The main purpose of setting these metadata fields is to check that they are transferredtransparently through the broadcast chain unaffected by routers/switchers, satellite links, etc. For any
program this metadata would be created as part of Dolby E authoring process. Using the Dolby
generator, the following metadata can be setup for Program 1:
Dialog Norm:
The normal audio level for dialog. Ideally all transmitted programs would have the samevalue.
BsMod:
Bitstream Mode indicates the type of audio service that the bitstream contains. Complete

The tool provides a real-time update of the differential delay between the video and the selectedaudio channel pair.
When analyzing an AV delay video test pattern and audio pulse, the differential delay between thevideo and the selected audio channel pair will be measured and displayed – with the display updated
in real-time.

Page 2-20l

A positive ( + ) measurement indicates that the audio pulse is lagging behind the videolA negative ( − ) measurement indicates that the audio pulse is ahead of the videolWhen video and audio are completely in sync, zero delay will be measured.
PHABRIX SxAUser Manual

The differential delay between the video and the selected audio is measured in 0.1 ms steps (to an
accuracy of 1 ms) with an operating range of +/−400 ms.
An Audio Delay offset can be applied to an Sx generated AV delay test pattern using the Generator →Video Out page. In the AV Delay analyzer, any delay amount that is not accounted for by thegenerated Audio Delay offset, will indicate delay introduced by the system under test.

The Sx modified EBU Tech 3305 AV Sync test pattern provides a constantly moving clapperboardthat when it closes shows a vertical white flash line for one frame.
When video and audio are in sync, the audio pulse will sound at the exact moment the white flash
appears. If video and audio are out of sync, there will be a differential delay between the timing ofthese two events.

The LAWO V_line AV Sync test pattern provides a constantly moving progress bar. When the
progress bar reaches the center frame of the test pattern, first a vertical white bar then a white flash
appears in the center circle.
When video and audio are in sync, the audio pulse should sound at the exact moment the white flash
appears. When video and audio are out of sync, there will be a differential delay between the timingof these two events.
To measure AV Delay in the Picture instrument, the Picture source should be set to the SDI input toanalyze the incoming video signal.
Note: The Picture source can also be set to view the generator output.

PHABRIX SxAUser Manual

Page 2-21

The A/V Delay selection menus and measurements display is located in the top right-hand corner of
the Picture instrument.
To measure the differential AV Delay, first ensure that a suitable test source is being used.
For the AV Delay measurement to be valid, the measuring Sx unit must be genlocked to a suitablereference, defined as either of the following:l

the SDI input being analyzed

lthe external reference to which the AV Delay test signal source device is locked.

If, however, the measuring Sx is also the source device generating the AV Delay test signal in a loop,
then a suitable reference is defined as either of the following:lExternal referencelFree run

Trying to lock the Sx unit to its own input signal is not valid.
The Sx unit reference input can be set in the Generator → GenLock page.
Switch on AV Delay measurement by selecting the appropriate test pattern type from the first A/V
Delay dropdown menu:lSelect either: OFF, EBU, LAWO

In the next dropdown menu, select the required audio group and pair carrying the AV delay audio
pulse – the timing of which will be measured relative to the video test pattern.
The AV Delay pulse can be carried on either an embedded SDI audio or AES channel:l

AES In, G1-P1, G1-P2, G2-P1, G2-P2, G3-P1, G3-P2, G4-P1, G4-P2

The Left (L) and Right (R) channel fields will display any measured differential delay between the video
and that audio channel in milliseconds (ms).
The status of the AV delay measurement tool (when switched on) is shown by the color of themeasurement display fields:
Yellow
Sampling in preparation for A/V Delay measurement. Not accurate during this period.
White
Measured differential delay. No errors detected.
Red
The correct AV delay pattern has not been detected and/or no AV delay pulse has been
detected
Audio-to-Video Differential Delay Testing:
Objective: To measure the imposed differential delay of the audio and video paths in the system
under test.

PHABRIX SxAUser ManualSignal Data (Option: PHSXOSD)The Signal Data menu shows the video signal as a data stream in several formats as described below.
In each mode, the data may be displayed in hexadecimal, decimal or binary formats. The binary
format is not available in grid mode. The data may also be displayed as 10-bit or 8-bit format.
To simplify scrolling around the SDI signal view, use the cursor keys to move the red focus rectangle
to the data display and press OK. The focus rectangle should change to a blue color and the cursor
keys allow the display to be scrolled in any direction. The menu keys at the bottom allow the Line /Sample to be adjusted by 10 or 100 in any direction.
Note: Note that the line number of a line of video changes at the end of active video. This gives
the unusual side-effect that the line number for pixels in horizontal blanking is the same as theline number for the active picture after that line.

Type
Grid:
In this mode the data is shown in an X-Y format with lines and samples at the same time.
This is a representation of the picture but in data format. If the cursor keys are used to
select the grid window and OK pressed, the cursor keys will scroll around the window. The
luma (Y) channel is shown in white whilst the Cr and Cb channels are shown in with a red or
blue tint respectively.
Strm:
This is one of three modes for displaying the samples on the current line only. The cursor
keys may be used to scroll the sample number when OK has been pressed. The info
column shows the type of data being displayed:l

AP - Active picturel

VBL - Vertical blankingl

HBL - Horizontal blanking

Comp:
This is a similar to the Strm mode above but in a component mode with Cr and Cb in different columns. See Strm mode above for the info column description.
Split:
PHABRIX SxAUser Manual

Page 2-25

This mode shows the two streams split into four parts to show Y, Y', Cr and Cb in separate
columns. See Strm mode above for the info column description.

Source
The analyzer can view either the video SDI input or the Generator output so that comparisons can bemade between input and output.
In1:
SDI Input
Out1:
SDI Output
Note: Note that when in Color modes other than YCbCr 422 10 bit, the pixel RGB or YCbCr
values are packed into 10 bit values across the different streams and thus will give unfamiliar
values. When the UnPack checkbox is selected the values in the active picture are unpacked to
RGB or YCbCr values.

Page 2-26

PHABRIX SxAUser ManualWaveform Monitor

The Waveform Monitor menu displays the selected input in the form of a waveform monitor.
The display may be restricted to a single line or all lines may be displayed at the same time. The
display can be formatted as all streams (Luma and Chroma) or just a single stream.
The streams may be in YCbCr or GBR formats. The line, sample and field controls all track the related
controls on other pages.
The All checkbox forces the waveform monitor to display all lines, overlaid on each other. Otherwise,
the specified line is displayed.
The waveform display format is set using the Setup button. The waveform monitor displays theselected signal in one of five formats as set by the Mode control:
YCbCr
The Y, Cr and Cb waveforms are displayed as three separate waveforms in a Parade
formatY
Only the luminance channel is displayed
Cb
Only the blue chroma channel is displayed
Cr
Only the red chroma channel is displayed
GBR
The green, blue and red waveforms are displayed as three separate waveforms in a
Parade format
Red
Only the red channel is displayed
Green
Only the green chroma channel is displayed
Blue
Only the blue chroma channel is displayed
RGB

PHABRIX SxAUser Manual

Page 2-27

The red, green and blue chroma channels are displayed as three separate waveforms in a
Parade format
XYZ, X, Y, Z
Settings in the Waveform monitor display the 2K-SDI XYZ color space in its native nonlinear form, so test patterns such as 2K. XYZ Legal Ramp will be displayed as curves
instead of straight lines.
X'Y'Z', X', Y, Z'
Settings in the waveform monitor display the 2K-SDI XYZ color space with a reverse transform to convert it to linear form, so test patterns such as 2K, XYZ Legal Ramp will be displayed as straight lines.
The next two controls show the vertical and horizontal magnifications. If either value is set to a value
other than x1, a vertical or horizontal offset is displayed at the bottom-right edge of the waveform
display. The offsets are set by moving the focus cursor to the waveform window and pressing OK.
The menu keys can then be used to scroll around the window. The offset is the same for all
magnification values so switching between x1 and x5 will not lose the offset used in x5 mode.
The vertical offset values are in signal level bits but displayed in the current scale units so switching
between scales will keep the same offsets.

Cursors
Cursors may be displayed over the waveform to allow measurement of time or amplitude values. The
cursor may be set to several modes:
Off:
Cursors are hidden
Pict.:
The cursor is displayed at the current pixel point. If in YCbCr or RGB mode, three cursors
are displayed. Otherwise a single cursor is displayed. The cursor position tracks across the
picture monitor and Signal Data tabs.
Ampl.:
Two cursors are displayed to allow measurement of signal amplitudes.
Time:
Two cursors are displayed to allow measurement of signal timing.
Both:
Amplitude and time cursors are displayed.
To use the cursors, use the navigation keys to move the focus to the waveform display and press OK.
You should then get a display similar to that below. Note that the menu keys shown depend on thedisplay mode and cursor mode.

The navigation keys now move the selected cursor around the waveform display which will scroll if
moved out of the visible area. The x10 and x100 buttons magnify the action of the navigation keys if
held down.
The Select Window button is only available in YCbCr or RGB modes and selects the window in which
the cursor is displayed.

Page 2-28

PHABRIX SxAUser Manual

The Amplitude Cursor and/or the Timing Cursor buttons switch the currently active cursor. In eachdirection two cursors are displayed. The currently active cursor is the one displayed as a full line
(rather than the dotted cursor). The bottom of the waveform screen shows the cursor measurementsin the current format which may be Decimal, Percentage or Hexadecimal for amplitude
measurements or Pixels/µs for timing measurements. The difference between the two cursors is also
displayed in absolute form.
The Cursor Mode button changes the current mode without having to leave the navigation window.
Source:
The analyzer can view either the video SDI input or the Generator output so that comparisons can be made between input and output.

Waveform Setup Dialog

The Waveform Setup menu allows the vertical and horizontal scale of the waveform display to be set
up.
Active Picture:
If checked, only the active picture is displayed for picture view and waveform monitor, allother VBI data such as TRS words ANC data and audio is blanked. This control tracks thestate of the ActPix control on the Picture.
Vertical Scale:
The axes and measurements for the waveform monitor can be displayed either in percentages or in hex or decimal values as required.
Horizontal Scale:
The timing measurements may be set in either pixels or micro-seconds (μs)

Vectorscope

The Vectorscope menu displays the selected input in the form of a vectorscope. This may be set toshow either the 100% bar positions or 75% positions. The color bar position boxes will change
according to the color space for the current input video standard.
Line
Allows a specific video line to be displayed. This is useful when test patterns are transmitted as part of a program on specific video lines.
All
The All checkbox forces the waveform monitor to display all lines, overlaid on each other.
Otherwise the specified line is displayed.
Field
The Fld 1 and Fld 2 modes allow specific video fields to be displayed.
Zoom
Allows the vector scope display to be zoomed-in to the Centre, Cyan, Yellow, Green,
Magenta, Red or Blue positions at x1, x2, x5 or x10 magnifications.
100%/75%
Selects the graticule scale to match the color bars being analyzed.
In1 / Out 1
Selects either the input to the Sx analyzer or the output of the Sx generator as the display.
The Vectorscope will automatically apply the appropriate transforms to display the images in YCbCr,
RGB and XYZ color spaces correctly. The color space transform to be applied is defined by the
SMPTE 352 payload.

PHABRIX SxAUser ManualSignal Information Menu
Overview
The Sig Info pages give a detailed view of the status of the input (or generator output) signal. They
are sub-divided into Video, Misc, and Ancillary (ANC) Status.

Video Status

The Video Status menu shows the status of the selected video input and displays any errors found in
the datastream.

CRC/EDH Errors
The CRC/EDH Errors section displays the EDH or CRC status of the analyzer input as appropriate forthe video standard being monitored. The status of each CRC/EDH count is displayed as the numberof seconds since an error occurred. The individual CRC fields may be reset individually or together.
The Running time field shows the time since the last error reset occurred. The error rate field shows
the number of errors per second. The running time will also be affected by the input being lost orintermittent. CRC errors are ignored on the switching line if the Ignore switch line checkbox ischecked.
ANC checksum errors are also detected and counted and may be logged.
When analyzing a 3G-Level B signal, the CRC status is displayed for each link or stream present
according to the input video format.

EDH Data
If the signal is SD (PAL-625 or NTSC-525) the EDH values for both active picture (AP) and full-field (FF)are displayed for each field. To enable engineers checking EDH integrity, the EDH values calculated
for active picture and full-field are also displayed.
Under normal conditions, the EDH-AP values should be constant, the full-field values may change if
audio or other ancillary data is embedded in the SDI signal.
The EDH flags for active picture, full-field and ancillary data are also displayed for diagnostic
purposes:

PHABRIX SxAUser Manual

Page 2-31

ues:
Unknown error status: Set to 1 if the previous device received an SDI signal from a device
not supporting EDH.
ida:
Internal Error Detected Already: Set to 1 if an idh flag was received by the previous device.
idh:Internal Error Detected Here: Set to 1 if a hardware error was detected in the previous
device.
eda:
Error Detected Already - Set to 1 if an SDI error was detected in the signal received by theprevious device.
edh:
Error Detected Here - Set to 1 if an SDI error was detected. In the case of ancillary data, thismeans that one or more ANC data packets had an incorrect checksum.
Note that there is only one EDH detector which is connected to the input currently being analyzed.
On an Sx instrument with multiple video inputs, only the current input being analyzed can check for
EDH errors.

Cable Length
The Sx instrument measures the cable length connected to the SDI input BNC and the measurement
is only an approximate value. The cable type may be set to one of the following:lBelden 8282, 1694A, 1505, 1855A.

l

Canare L-5CFBlImage 1000l

Percon VK 5lDraka 0.6/2.8 AF

The selected cable type will affect the cable length measurement.

Active Picture CRC
16-bit CCITT CRCs are calculated for the active picture data of the received signal. This can be used
to give a known value for known static picture content and allows the user to determine if the active
picture content is as expected.
CRCs are calculated independently upon each 10-bit stream (luminance and chrominance) of theinterface.
For example, the generated 1920x1080, 100% bars in YCC422-10 should always produce a luminance
CRC of 0x0AB4 and a chrominance CRC of 0xB88E, no matter what scanning mode (interlaced,segmented frame or progressive) or frame rate is used.
Note: When using 4:4:4, 4:4:4:4 or 12-bit video formats (in dual-link or 3Gbps) the CRCs arecalculated for each of the packed 10-bit virtual interfaces and will therefore generate different
values from those for YCC422-10.

Page 2-32

PHABRIX SxAUser ManualMisc Status
The Misc Status menu displays the auto-detected and SMPTE ST352 (VPID) parameters of theselected SDI source and highlights any detected errors or unsupported parameters.
When analyzing a 3G-Level A or B signal, the SMPTE 352 status is displayed for each link or stream
present according to the input video format.
Note: The unit now supports the SMPTE 352 video payload identifier (VPID) on a single interfaceof 4 x 3G and 4 x 1.5G links.

Payload ID – SMPTE 352
If the unit detects a SMPTE 352 ancillary packet, the detail of the packet content is displayed in thissection in both hex and decoded format.
The display lists the following elements contained in the SMPTE 352 packet in decoded form:l

Video Format
These sections display the currently auto-detected pixel counts, active line count and the frequencyof the selected input source.
Note: The displayed video frequency is correct only if the unit has been calibrated and is freerunning or has been connected to an accurate reference input.
If the input signal is not a known signal, for example, ifthe line count or pixel count is not recognized,
the input status on the top line will show Invalid but the values in this section will be updated every
few seconds.
The Re-Sync counter displays the number of times the SDI data has been re-synchronized and canhelp detect intermittent SDI signal problems. Press Clear to reset this counter.

Video Timing

The Video Timing menu displays the relationship between the selected video input with respect tothe locking reference input.
The timing of the SDI input signals is displayed relative to the external reference. If no reference ispresent, then an error message is displayed. If the signal is timed to within +/− 2 samples the values
are displayed in a black font, in lines and samples (spl). If mistimed, then they will be displayed in red.
A bar graph also displays the timing value which may either be line timing (+/− 0.1 lines or +/− 0.5 lines)
or frame timing (+/− 0.5 frame). The total timing value is also displayed in microseconds.
The red arrow on the bar shows the SDI input timing and the blue arrow shows the current target
timing point. The brown vertical line shows the timing of the reference signal.
To compare timings of different signals, connect the signal to be compared to the SDI input andselect the ->Offset button to make this the current offset. All future timings will be relative to this offset
value.
To clear the current offset, move the focus to the two offset fields, press OK to edit them and thenpress Default.
Note: All timing measurements are relative to line 1 on the SDI signal and line 1 on the reference
signal. This can lead to different values from other test and measurement instruments that
include an SD (PAL/NTSC) offset in their calculations. By comparing line 1 timings, the Sx
instrument can be used to measure time delays accurately through up / down / cross converters.

PHABRIX SxAUser Manual

ANC Status
The Ancillary Packets Status tool provides broadcasters, studios, OB and broadcast manufacturers
with a detailed analysis of the ancillary data present in an SDI signal.
A simple grid layout provides a quick overview of the available VANC/ANC ancillary data for anengineer. The packet type is then displayed as present, absent or red if in fault. Simple icons next tothe packet indicate the fault. Each ancillary packet available from the grid view can be set to enable
logging and then presented together with other information in the events window of the logging
menu.
This tool further allows additional user-defined selections with the appropriate DID or SDID code. Any
ancillary packet code can be saved down for future recall. Note that the Ancillary Packets Status tool
does not fully decode the ancillary data but is used to identify whether the packet is present in thesignal.

The ANC Status menu shows which ANC packets are present on the SDI input and whether they
have any errors. Each field is color-coded according to whether the ANC packet is present (White),
missing (Grey), has errors (Red), or has previously had errors (yellow).
If the field has errors then a symbol beside the field shows which error type it is. The bottom of thepage shows the symbol for each type of error. The Reset button resets the Previous Errors state.

The Setup button and dialog allows user-defined ANC packets to be configured.
The packet name, data ID (DID) and SDID may be specified for up to three user-defined ancillary
packets. The Stream field specifies whether the packet should be on the chroma stream, theluminance stream or both.

PHABRIX SxAUser Manual

Page 2-35

ANC Inspector (SDI Data Option: PHSXOSD)The SDI Data Option PHSXOSD allows Ancillary data packets to be detected and checked for errors.
The ANC Inspector menu displays details of the ANC packets.
The packet type can be selected using either the dropdown list of known packets or the DID/SDID
number fields. If the DID/SDID values match a known type, then that type will be selected in the
dropdown list. This may be further filtered using the checkboxes on the Setup dialog.
The Line and sample number of the detected packet is displayed to facilitate debugging ofgeneration equipment. The complete data packet is displayed as a hexadecimal grid at the bottom of
the page and may also be decoded into text above the grid.
If an error occurs in the packet, the header and checksum are displayed in red.
The display of data may be frozen by pressing the Freeze checkbox.
The Found description shows in which stream the ANC packet was detected, Chroma or Luma andwhat kind of trigger was detected. This may be:
C:
Checksum Error
D:
DBN (Data block number) Error
P:
Parity Error
G:
ANC Gap error
Several of the above flags may be displayed at the same time.
The detected ANC packets may be filtered using the Setup dialog. This allows a great deal of
freedom in setting when the display will be triggered.
If the On Trigger checkbox is selected the data packet will cause the display to be frozen and theFreeze checkbox will turn red when a trigger condition is met as described below. Uncheck Freeze
to restore normal operation.
The ->Cursor button will copy the Line and Sample numbers to the SDI data view cursors to simplify
navigation to the ANC packet under investigation.

Page 2-36

PHABRIX SxAUser Manual

ANC Inspector Setup

If the Setup button is pressed a dialog box allows the ANC packet trigger parameters to be set. The
trigger parameters allow only selected lines to be checked or excluded when checking for thepresence of packets.
Line Range Filter:
If either of the Line Range filter checkboxes are checked then the range of lines that the
ANC inspector will check is restricted to that range. If the dropdown below the range is set
to Inside then it will only check ANC packets within the range (including the start and end
lines). If set to Outside it will check only ANC packets outside the specified range.
HANC/VANC Filter:
Provides another filter for simpler selection of the area in which to search for packets. It
may be selected to search the HANC area, the VANC area, or both areas.

Error Triggers
If any of the Errors checkboxes are selected, then the ANC packet data will only be displayed if anerror occurs. The error states detected are:Checksum:
A checksum error in a packet was detected. (Sum of data between DID and final UDW)DBN:
A Data Block number error was detected in an audio packet. The DBN field (in the sameplace as the SDID) of an audio packet should either be 0 and never change, or incrementfrom 1 to 255 and then start at again at one.
Parity:PHABRIX SxAUser Manual

Page 2-37

A parity error was detected for the DID, SDID and DataCount words in a packet. (Even Parity used and bit 9 is the inverse of bit 8.)
ANC Gaps:
The ANC packets were separated by a gap containing video blanking data. EDH (DIDD=0xf4) packets are ignored. Note that if an EDH packet is marked for deletion, this will result in an ANC GAP error.
The Setup dialog also shows when an ANC packet has been detected and where it was found. This
makes changing a filter simpler as the effect of the filter can be determined without closing the dialog.
This dialog also allows the user defined ANC packets to be configured.

PHABRIX SxAUser ManualAudio Menu
Meters

The audio Meters menu displays up to 16 audio channels. The source for each block of eight meters
may be independently set to allow simultaneous metering of eight inputs and eightoutputs or all 16
channels in an embedded SDI stream.

If AES inputs or outputs are present, then these may also be metered. At the bottom of each meter isthe current audio level for that channel in dBFS (decibels relative to 0 dB full-scale).
The scale used by the meters may be set to −18 dB or −20 dB according to the standard operatinglevel used.
If the Dolby option (PHSXO-DAG) has been purchased, the meters may be set to display the encoded
Dolby levels for the specified audio pair or AES input.
Note: Dolby audio cannot be heard on the speaker as a Dolby decoder is not present.

PHABRIX SxAUser ManualDolby (Dolby Analyzer Option: PHSXO-DAG)

The Dolby Analysis option allows display of the Dolby E metadata present in the selected audio
stream and determines whether the Dolby E packet is timed correctly on the SDI video stream.
This option therefore allows the Dolby E aspect of the signal to be timed correctly at all stages in a
broadcast chain.
Checks can be made to see that the Dolby E has been created correctly and transferredtransparently through the broadcast chain, unaffected by routers/switchers, satellite links, etc.

Overview
There are a number of Dolby broadcast digital audio standards that transport audio data over an
SMPTE 337M AES carrier with a 48 kHz sample rate:l

Dolby El

Dolby Digitall

Dolby Digital Plus

These standards can be used to transport mono, stereo, 5.1 and 7.1 audio programs:
Dolby 5.1
Involves five channels for standard-range speakers (20 Hz to 20,000 Hz) (right front, center, left front, rear right, rear left) and one channel (20 Hz to 120 Hz allotted audio) for the
subwoofer-driven low-frequency effects.
Dolby 7.1
Uses six channels in the primary program (Independent Substream) for a standard 5.1 surround sound mix and then the remaining two channels in an ancillary program (Dependent
Substream) to provide the additional down-mix.
Dolby E
Dolby E is an audio encoding and decoding technology developed by Dolby Laboratories that allows
up to eight channels of audio (mono, stereo, 5.1 or 7.1) that for a primary program (Program 1) andoptional ancillary programs. These eight channels are compressed (lossless) into a digital stream thatcan be transferred between compatible devices and stored on a standard stereo pair of audio tracks.
The most elaborate mode in common use is Dolby 7.1 which uses all eight channels to provide
surround sound.
PHABRIX SxAUser Manual

Page 2-41

Dolby Digital
Dolby Digital (AC-3) is a perceptual audio system for digital audio that allows the reduction of dataneeds to deliver high-quality sound. This system was developed primarily for DTV, DVD and HDTV.
This format allows up to six channels of sound (mono, stereo or 5.1) in the form of a single ‘program’that can be delivered at different bit rates. These 6 channels are compressed (lossy) into a digital
stream that can be broadcast. The most elaborate mode in common use is Dolby 5.1 with uses all six
channels to provide surround sound.
Dolby Digital Plus
Dolby Digital Plus (E-AC-3) is a more advanced version of Dolby Digital that provides a more efficientencoding algorithm offering a primary program and optional ancillary programs. These can be
optionally delivered at lower bit rates than Dolby Digital.

Analyzer Reference
For correct decoding of Dolby E data, the internal audio circuitry requires a reference that issynchronized to the input signal. The Generator Reference must not be set to Free-Run or Dolby E
errors may be detected. The description field will display Invalid Reference if an incorrect referenceis selected.

In this example, the SDI signal contains embedded audio with Dolby E present on one or more audio
pairs. The Sx instrument needs to lock its internal audio clock to the SDI signal Generator → GenLock→ GenLock Source → Input-1 and the Dolby Timing source should be set to SDI.

In the example above, the AES signal contains a Dolby E stream. The Sx instrument needs to lock its
internal audio clock to the external reference signal Generator → GenLock → GenLock Source → 1Ref
and the Dolby Timing source should be set to Ext.Ref. The AES source must be locked to the samereference as the Sx.

Page 2-42

PHABRIX SxAUser ManualSource Selection
The Dolby E may be monitored from any of the SDI input embedded audio channel pairs or the AES
input.

Dolby E Framing Values
It is important for the Dolby E packet to be positioned well away from the video switching line so that
Dolby E packets are not corrupted by downstream switchers. At all places in the signal chain whereaudio can be delayed by a different value to the video, the Dolby E packet needs to be re-timed toensure that this timing specification is met. The position of the Dolby E packet in the video frame isdisplayed in lines and microseconds (µs).

Dolby E Timing Source
Dolby E timing may be measured relative to the SDI input or the External reference. If the Ideal
checkbox is checked, the Dolby E Frame timing is relative to the normal position that it should be, i.e.,
it should be as close to 0 as possible. Each video standard has a specified Ideal line number on which
the Dolby E packet should start. If the Dolby E timing line is outside the valid range of lines it will be
displayed in red. If it is outside the ideal range it will be displayed in dark green – this is still a valid
Dolby E position but not recommended by Dolby. The timing measurement is always displayed interms of the SDI input lines and thus if an AES input is used as the Dolby E source, the line position will
not be displayed.
If you do not have the same reference as the SDI source, you will have to set the Reference Source
and Dolby Timing Source to be the SDI input.
Note: If Dolby E is present on a fast frame rate signal (50p, 59p or 60p) then it should always bereferenced to an interlaced reference at the same field rate as the packet length is longer than asingle frame and must start at the beginning of an even numbered frame.

Command Scripts (Option: PHSXOS)The Command Scripts menu allows the Sx instrument to run predefined scripts. This can be used toautomate testing of signals.

Steps, Actions and Parameters
Command scripts are text files with a file extension of .cmd. They are formatted with one step per line.
The line is formatted as: <StepNumber>-<StepAction>:<StepParameters> for example: 5-Pause:4s
StepNumber is a numeric value representing the numeric order of steps in the command script,
starting at 1.
Step Action is one of:
ARCHIVE:
Used to specify the archive file to be loaded when the script is run. This makes sure that all
the memories required for the test have been loaded. The archive file is loaded every time
the script is run so if you make changes to any memories you must use the Export/Archive
section on the System-Memories tab to backup the current memories.
LOADMEM:
Loads the memory specified in the StepParameters field – must be a numeric value 1...num
memories.
CHECKERRS:
Check for CRC/EDH/ANC checksum errors in StepTime seconds. If there are any errors an
event is added to the event log and the sequence pauses with a message to continue or
abort. If the SDI input signal is missing, this is treated as an error.
CHECK_AP_CRC:
Check for changes to the active picture CRC value in StepTime seconds. An event is
added to the event log.
PROMPT:
This will put a short prompt on screen in a dialog asking the operator a question and waiting for OK to be pressed to continue. The time field is ignored and the parameter following
is the text displayed.
CLEARLOG:
This clears the Event Log

Page 2-50

PHABRIX SxAUser ManualDISABLEEVT:This disables Event logging
ENABLEEVT:This enables Event logging
CLEARERRORS:This clears all error counts (EDH/CRC etc.)
LOGCOMMENT:
Add the specified comment to the log file – useful to document the stage in the test process
PAUSE:
Pause for the specified number of seconds to allow another process such as loading test
patterns to complete.
SAVESTATUS:
Save the current system status as an XML file.
SAVEIMAGE:
Save the selected image as a bitmap file in the current scripts directory. Filename must be
specified.
SELECTTAB:
Show the selected tab to allow the user to view something.
SEL_USER:
Select user – users are comma separated
CHECK_METER_LEVEL:
This action checks that the level for any visible meters is at the level set by the meter scale.
This level may be −18 dB or −20 dB. If the level is over 1 dB greater or less than that value
an error will be inserted in the log and report files. If any groups are missing, these will beignored by the test. Testing may be limited to specified audio pairs as set up on the Log
Setup page.
CHECK_METERS_OFF_LEVEL:
This action checks that the level for any visible meters is below −70 dB. If the level is abovethat value an error will be inserted in the log and report files. If any groups are missing,these will be ignored by the test. Testing may be limited to specified audio pairs as set upon the Log Setup page.
CHECK_AES_INP:This action checks that the AES input signal is present and has no errors for the specified
time period.
Step Time is a numeric parameter value in seconds for steps that are time-controlled 0....nCreating Command Scripts

PHABRIX SxAUser ManualNetwork

PHABRIX Sx is fully network compatible and has a complete network interface to allow control of any
Sx instrument from any other unit.
The Network menu allows the Sx instrument to be configured as part of a network.
Note: If the Sx instrument is switched on without the network connected, you will have to selectRe-connect button to set networking up correctly. This is because the Ethernet connection autosenses whether it has to swap the cable over, which means that you can use any Ethernet cablewith the Sx instrument, but it also requires the Ethernet connection to be present when startingup.
If the DHCP checkbox is enabled, then the Sx instrument will automatically attempt to request an IP
Address from any network to which it is connected, as long as a DHCP server is available on the
network.
If your network uses static (nonchanging) addresses, you will need to contact your network
administrator to get an address assigned to your instrument, and to get the Subnet mask and default
gateway address. To edit the settings, select Setup. These details can then be entered in thecorresponding boxes in the menu. If the DHCP checkbox is enabled, these values will not be
editable. Select each numeric box in turn and use the up and down cursors to pick the required value.
When the IP Address, Subnet Mask, Default Gateway and DNS Server values have been setup, use
Re-connect to attach the Sx instrument to the network.

Remote Control of Sx Instrument (Option: PHSXOR)To allow remote control of an Sx instrument, you must have the TCP/IP address of the instrument set
and the Remote Ctrl On checkbox selected.
The list box shows a list of current connections made to the instrument. This includes the webbrowser connection (127.0.0.1) which may be seen intermittently as the web browser connects every
few seconds and then disconnects again. See the remote control documentation available fordownload for more information on the protocol and method of control.
The Sx instrument uses a default Port Number of 2100 for remote control access (See Remote Control
SDK documentation on Download section of Web Site) This port number may now be changed if it
conflicts with other applications in your system.

PHABRIX SxAUser ManualLogging Menu
Overview
Logging allows events to be detected and recorded for future examination. The events to be logged
can be specified so that unwanted events do not appear in the event log. If a system has a problem
with intermittent signals, the Sx instrument can be connected to that source and can be left for several
days to log any errors. At the end of that period the log can be examined and the time and date ofeach error noted.

Events Log

The Events menu displays a list of events with a time stamp showing when they occurred.
Entries in the Event Log are classified according to their severity with an initial letter as follows:l

C: Control (change of state)l

E: Eventl

I: Informationl

W: Warning

Pressing the OK button on the front panel when the highlight is on the event log page allows theevent log to be scrolled to view all events in the list. The currently selected event is shown on theevent log header. The date format may be changed using the date Format dropdown on the System→ Misc page. The event log may be cleared by pressing Clear Log; a confirmation dialog will be
displayed . A date-stamped mark may be inserted into the event log to allow users to see when a test
started or when a significant event occurred using the Add Mark in log button.
Note: The event log displays only changes in status, so if the input is always in error and nevergood, an event will not be recorded. To obtain a view of the complete state of the instrument
requires reviewing the current status in addition to the event log.

PHABRIX SxAUser Manual

Page 2-61

Log Setup

The Log Setup menu allows specific events to be tracked by the Sx instrument.
Note: The events to be logged are set-up on this page by checking the appropriate Log
checkboxes.

Audio Thresholds
This section allows the thresholds for audio events to be set. If the audio level for a channel is higher
than that specified in the Clip or High fields for the number of seconds specified, then an event will be
added to the event log. If the audio level for a channel is lower than that specified for the Quiet or
Muted fields, then an event will be added to the event log. Logging may be limited to specified audio
pairs.

Video Status
This section allows specific video status events to be logged:
Output Standard:
A log event will be added whenever the generator video standard changes.
Reference Status:
A log event will be added whenever the external reference standard changes or theexternal reference input is lost or re-appears.
Input Status:
A log event will be added whenever the input video standard changes or if the input is lostor re-appears.
EDH/CRC:
A log event will be added whenever an EDH/CRC error state changes. If the EDH/CRC
state is correct, the event will show OK, else it will show FAIL. Separate Luma and Chroma
CRC events may be shown. Note that EDH/CRC events may occur when an SDI signal isconnected or removed.
TRS Errors:

Page 2-62

PHABRIX SxAUser ManualIf the number of lines changes or line length changes during a frame, the input video will
be detected as the TRS changing and an event logged. If the signal continues changing
only a single event will be logged. If the SDI signal has a static line count and line length forfive seconds, a TRS OK event will be added to the log. This reduces the number of log
events for a bad SDI signal.
Picture CRC:
This should only be used for static single-frame test patterns (do not use for Zone Plate,
dynamic broadcast signals or Checkfield/Pathological test patterns which are two frames
long at HD). This can be used to log changes in the CRC for the active picture (a uniquevalue for each test pattern). If the CRC changes and was previously OK an error is added tothe event log. If the CRC is the same as the last frame for five seconds an OK event will be
added to the event log. If the active picture CRC is continuously changing, therefore, only
one event will be entered in the log until the picture remains static, at which point an OK
event will be added.

AES Status
This section allows AES audio errors to be logged:
Errors:A log event will be added whenever the embedded audio error status changes. This may
be due to a Data Block Number error, ECC error or phase error status change. The event
entry will detail which state has changed.
Input Status:
A log event will be added if the AES signal disappears or appears.

Dolby Status (Requires Dolby Analysis Option)
This section allows Dolby errors to be logged.
Errors:Will add an event to the event log when a Dolby input stream is detected or lost. An event
will also be added if a CRC error is detected in the Dolby metadata stream. If an error is
detected in the Dolby E stream, it may mean that the Dolby E stream has not been synchronized with the embedded audio clocks.
Timing:Will log if the Dolby E frame timing is outside the Dolby-specified Ideal range. A Warning
event will be given if the signal is OK but slightly outside the range and an Error event if it ison an invalid line.
Common Metadata:
Will log any changes of the common metadata (Program Configuration, Bit Depth, Frame
Rates.)
Program Metadata:
Will log any changed program metadata. This can be useful for following changes to a program stream over a long period of transmission.

Logging
This section controls all logging events:
Clear:
Clears all entries in the event log.
PHABRIX SxAUser Manual

Page 2-63

Enable:Enables the logging process. If this is not checked, no events will be added to the log. Thisis a simple method of turning off all logging temporarily.
Beep:Causes the Sx to emit a short tone when an Event is added to the log. Note that the beep
will occur even if the Speaker is set to Mute.
SYS Errors:
Allows system errors to be displayed in the Event Log if they occur. If you are having problems with your Sx, checking this box can add events that may help PHABRIX to determine
the nature of the problem.
System Info:
Allows the system to report additional internal messages in the Event Log if they occur. If
you are experiencing problems with your Sx instrument, checking this box can add events
that may help PHABRIX to determine the nature of the problem.
Save:
Saves the current event log to a text file in the currently specified language. The log file created, logfile.txt may be downloaded using an FTP connection. If the CSV checkbox isselected then a comma separated value file will be created.

Log Time Limit
The time when logging is enabled may be restricted by the time of day. Logging will start at the
specified start time and end at the specified end time. The specified times must be after the current
time. Uncheck the Enable checkbox to log at all times. Logging must be enabled using the checkbox
above for this to work.

Log ANC Status

Speaker Menu
Overview

The Speaker menu controls which audio pair can be heard on the loudspeakers and headphone
output of the Sx instrument. The Sx instrument contains a stereo loudspeaker and associated stereo
headphone socket which can be connected to any of the audio input or output channels or pairs.
The Mute checkbox allows both signals to be muted.
A volume control is available to adjust the level to headphones and speaker together. The balance
control can be used to adjust the Left-Right balance for the source being monitored.
The monitored source can be set to the input or output of the Sx instrument, and the input and output
sources can be set independently to either a stereo pair or single audio channel.
The Source is used to select the specific input that is to be heard.
The speaker can be muted when headphones are plugged in by selecting the checkbox Mute Spkr
if Headphones.
Note: When listening to an audio source, the Sx instrument needs the audio to be synchronouswith that of the Sx Generator. If this is not the case, clicks will be heard on the speaker. Either
connect the Sx instrument reference to the same reference as the SDI input source and set theGenerator → GenLock → GenLock Source to External or Input-1.

two channel, linearly represented digital audio data.
Alignment Jitter
Artefacts above the specified threshold frequencies of (1 kHz for SD-SDI signals and 100
kHz for HD-SDI signals). Typically, video equipment cannot tolerate Alignment Jitter whichcause decoding errors due to incorrect sampling of the data stream because the SDI
Clock transition occurs on the edge of the data sample instead of in the center of the data
sample.

Specifications
SxA Instrument
Operating Environment
Operating Temperature:
0° to 40°C
Operating Humidity:< 85% RH (non-condensing)If the unit is operated at a higher temperature, there is a possibility of a fire hazard.

If the temperature is changed rapidly from a cold environment to a hot environment, moisture can becreated internally which can cause malfunction or damage the unit. Allow the unit to sit for 30 minutes
without power applied to reduce any possibility of condensation.
If the temperature rises above 55°Celsius a warning dialog will be given. If the temperature rises
above 65°Celsius the unit will be switched OFF.
Under both conditions, an event will be added to the event log to show what happened.

Expected Behavior
LCD Monitor
The LCD may have some pixels that are always turned ON or always turned OFF. This is normal andshould not affect normal operation.

LCD Flicker
The unit supports many video standards. The input SDI signal is displayed asynchronously and may
flicker on the waveform display or picture display. The unit stores the input SDI signal internally, andthen reads the internal frame using the LCD sync signal, which is asynchronous to the input SDI
signal. LCD flickering may occur if a frame is skipped or repeated.

Remote Network Operation
Remote network operation is only guaranteed when connected to a local machine.

Maintenance
General Maintenance
The Sx instruments have been designed to need minimum maintenance. The use of low powercomponents means that there is no need for large amounts of cooling and therefore there is no needto clean fan filters.
PHABRIX SxAUser Manual

Page C-1

The case can be cleaned by wiping gently with a soft cloth, lightly dampened with a neutral cleaning
agent. A screen cleaning cloth may be used to clean the LCD. Do not apply force to the LCD whencleaning or it may be damaged.
Warning: Always remove the power supply from the instrument and turn OFF before cleaning.
Do not allow any water or other liquid to enter the instrument while cleaning.

Preventative MaintenanceFor long reliable use of the Sx instrument please take the following precautions:
l

l

l

l

Install the Sx instrument in a position which has adequate air flow and is not in direct sunlight.
Ensure that connecting cables are tied back so that they do not put strain on the rack mounts
and that the do not obstruct air flow.
Ensure that the fan grilles are not obstructed.
Avoid installations where there are dramatic changes in temperature, high humidity and areas
contaminated by dust, smoke or construction debris.

l

Avoid installations that may be affected by vibration.

l

Do not exceed the rated operation of the Sx instrument, i.e., temperature and signal levels.

Warning: The unit should only be operated between 0 and 40°Celsius. If the unit is operated at ahigher temperature, there is a possibility of a fire hazard. Charging the unit at a higher
temperature will reduce the life of the battery and could cause permanent damage. If thetemperature is changed rapidly from a cold environment to a hot environment, moisture can becreated internally which can cause malfunction or damage the unit. Allow the unit to sit for 30
minutes without power applied to reduce any possibility of condensation. If the recommended
charging temperature is exceeded a warning dialog will be displayed. If this occurs,
disconnect the power adapter and allow the unit to cool before resuming charging.
If the temperature rises above 55°Celsius a warning dialog will be given. If the temperature rises
above 65°Celsius the unit is automatically switched OFF. Under both conditions, an event will be
added to the event log to show what happened.

Software MaintenanceInstalling New Software
Note: Make sure that the unit is connected to an AC power source before starting the software
upgrade. The software upgrade may take up to an hour to complete.
New software can be installed on the Sx instrument using two different techniques depending on thelocation of the Sx instrument, the type of network access that the Sx instrument has and you
company’s IT policy.
Note that during the installation process the instrument will not be available for use.
Note: Note also that any existing Presets stored will be archived and will need to be restored ifthey are required. See the section Memories for details on restoring presets archived by the
installation of a new version of software.

Software Download from the Internet
Using the Sx instrument’s LCD screen (access via a web browser), and the Sx instrument has Internet
network access, you can download and install directly onto the Sx instrument from the browser:
This is a two-stage process, first the new software needs to be downloaded then the new softwareneeds to be installed.
1. In the System - Network menu (Network window on Monitor Output) check that the network settings are correct and that the instrument is connected to the internet through the Ethernet connection.
2. From the System menu, select Engineer (Engineer Setup window on Monitor Output) to download the latest software version. Pressing the Download button will cause the current releaseof software to be downloaded from the PHABRIX website.
Note: Note that multiple releases of software may be stored on the Sx instrument so aprevious release can be re-installed if required.
This will take a short time dependent on the connection to the Internet. Once the download hascompleted, the software will be checked for errors before being stored on the instrument for
future installation. If the latest software is already present on the unit, no software will be
downloaded and a message will be shown.
3. To install the downloaded software on the Sx instrument, select the release using the field withreleases listed. The largest number is the latest release. Select the Install button and a confirmation dialog will be shown. Press Yes and the installation will start. This process takes several minutes to decompress the software, extract the files and then reprogram the hardware. If
an error is given during the installation, retry the installation and or download. Do NOT switch
the instrument off until an installation has completed correctly.
Once the installation has competed, if Reboot after Install is checked the instrument will restart with the new software installed. If not checked then the instrument should be switched off
and on again manually.
Note: As part of the installation procedure, all memories are archived to a backup file andthen deleted. They can be restored from the System → Memories page using the Restore
button and selecting the archive: _Before_Upgrade.

The software release notes can be viewed by selecting the Changes button.

FTP Transfer from a Connected PC
If the software cannot be installed, for example because the Sx instrument does not have Internet
access, you can transfer the software files directly to the Setup folder of the Sx instrument using the
PHABRIX FTP client:
1. Download the latest Sx software version from the PHABRIX website then drag the zip file to the
PHABRIX FTP client (also available from the PHABRIX website).

To connect to the instrument, you will need to use the PHABRIX FTP client available from the
PHABRIX website. This connects to the Sx unit using IP address of the unit (as host name) with:l

Username: sxuserlPassword: phabrixsx

2. In the PHABRIX FTP client enter the IP address of the Sx unit to be updated.
Note: If a static IP address has been assigned to your Sx unit, be sure also to set a valid
default gateway address. Contact your network administrator for these. If connecting
directly between the Sx and your PC, you must set the default gateway to the IP address of
your PC. See System – Network for information on configuring the network settings on theSx.
3. In the PHABRIX FTP client select the zip file for the new software and press the ‘Copy to Sx’ button.
This will copy the new software files to the Sx instrument’s ‘Setup’ folder, updating the existing
files as necessary. This can take up to 20 minutes depending on the connection speed.
4. Once the PHABRIX FTP client has finished copying the files to the Sx unit, use the menu: System → Engineer to locate the new software version in the Software Upgrade section of themenu, then select Install.

Page C-4

PHABRIX SxAUser ManualWait for the new software to be installed. The progress will be indicated on screen.
During this time the software will be decompressed, files will be extracted and the hardware(FPGA) will be reprogrammed. If an error is given during the installation, retry the installationand or download. Do NOT turn the unit off until an installation has completed correctly.

Reverting to an Earlier Version of Software
If you need to revert to an earlier version of software:
1. Use the menu: System → Engineer to find the version of software you require in the Software
Upgrade section of the menu then select Install.
2. Wait for the new software to be installed. The progress will be indicated on the front panel
screen and on the Monitor output.
During this time the software will be decompressed, files will be extracted and the hardware(FPGAs) will be reprogrammed. If an error is given during the installation, retry the installationand or download. Do NOT turn the instrument off until an installation has completed correctly.

Sx File Structure
The Sx instrument uses Linux as its operating system and several directories in the file system areprovided for user-specific files.

Patterns Directory
The Patterns directory contains several subdirectories for the related video standards. Test pattern
files should be placed in the correct directory for the video standard in use. i.e., if a 720p video
standard is being used, only the test patterns in the 720yuv directory will be available. You may havea test pattern with the same name in different pattern directories but they should have the correct sizeand color type (RGB/YUV) for the directory that they are in or they will be converted and may losecolor accuracy.
Patterns that are too large for the current standard will be clipped to fit; patterns that are too small will
gain a black border and will be centered on the output image.
Test patterns are .pat files for the standard line-based pattern files or user files. Supported user fileformats are:l

Windows bitmap files (.bmp). We support 24 bit uncompressed bitmap formats only.

l

10 bit video files (.dpx) We support 10 bit RGB/YUV formats only in Left to Right orientation.

l

Yuv and qnt files (8/10 bit packed yuv only)lTarga (.tga) files which are compressed or uncompressed 8 bit RGB files. We support Left to
Right orientation only.

Phabrix specific .pat, .rgb, .yc4 files.
Note: Note that bitmap files which are RGB will be converted to YUV internally as appropriate tothe output standard. This will mean that not all valid YUV values can be output. If dpx YUV files
are used then all valid values may be output.

Scripts Directory
Command scripts may be downloaded into this directory.

PHABRIX SxAUser Manual

Page C-5

Setup Directory
The Setup directory contains the installer files for different releases of the software. Each release iscomprised of a .tar.gz file and is self-contained. If a release of software is copied onto the instrument,
the list of available releases will be updated within a minute.

Idents Directory
The Idents directory contains bitmap idents as used by the generator. Supported user file formats are:l.bmp (Windows bitmap files: 24 bit only)l.dpx files (10 bit video files)l.yuv files (8/10 bit packed yuv)l.tga (targa files)

Note: Note that bitmap files are RGB and will be converted to YUV internally as appropriate tothe output standard. This will mean that not all valid YUV values can be output. If YUV files areused(.dpx), then all valid values may be output.

Fonts
The fonts available for use by the generator to add text idents may be enhanced by downloading
new True Type fonts (.ttf) into this directory.

Screen Captures
The unit enables you to capture a screenshot of the active screen as follows:
1. With the desired screen displayed, hold down the OK button on the unit until you hear a beep.
2. Wait a few seconds for the unit to save the file. It will then dispaly the following dialog showing
the name of the saved bitmap file.

Make a note of the path and file name so that you can retrieve the file as described below.
Retrieve a saved screenshot from the unit as follows:
1. Open your web browser and access the unit, enter: http://<IP_address>
2. Click the Downloads button at the bottom right of the Sx display on the website.
