Vertical Scale: The scale of each grid in the vertical direction. For example,
when the vertical scale is 1.00 V/div, the full scale of the oscilloscope is 1.00
V/div * 8 div=8 V.

Vertical Offset: The offset of the channel in the vertical direction. When thevertical offset is 0, the channel offset indicator is located in the middle of thevertical axis.

Probe Attenuation Factor: Set the probe attenuation factor to match theactual attenuation of the probe. The oscilloscope automatically calculates thevertical scale according to the probe attenuation factor. For example, thevertical scale of the oscilloscope is 100mV/div with 1X attenuation, and 1 V/div
if the attenuation factor is changed to 10X. When inserting a standard 10X
passive probe with a probe sense terminal, the oscilloscope will automatically
set the factor to 10X.

Coupling

DC: All of the input signal frequency components are passed to the display.



AC: The signal is capacitively coupled. DC signal components are rejected.
See the datasheet for details of the cut-off frequency.AC coupling issuitable for observing AC signals with DC offset, such as power ripple.



GND: The channel is grounded by an internal switch. GND coupling is used
to observe the zero offset error of the analog channels or determine thesource of noise in the waveform (from signal or from oscilloscope itself)

Bandwidth Limit
Full bandwidth passes through signals with high-frequency components, but it
also means that noise with high-frequency components can pass through.
When the frequency component of the signal is very low, better signal-tonoise ratios (SNR) can be obtained by turning on a bandwidth limit. The
SDS6000A provides two hardware bandwidth limit options: 20 MHz and 200
MHz.

Probe Settings
The SDS6000A provides 1X, 10X, 100X, and custom probe attenuation factor
options. The custom values can be between 10-6~106. The oscilloscope willautomatically convert the vertical scale according to the current probe
attenuation factor. For example, the vertical scale of the oscilloscope under 1X
attenuation is 100 mV/div, and the vertical scale will be automatically set to 1
V/div if the probe attenuation is changed to 10X. If a standard probe with areadout terminal is connected, the oscilloscope will automatically set the probe
attenuation to match the probe.

Impedance

1 MΩ: When a passive probe with high impedance is connected, theimpedance must be set to 1 MΩ, otherwise the signal will not be detected.

50 Ω: Suitable for high-frequency signals transmitted through 50 Ω coaxial
cables or active probes. This can minimize the amplitude distortion caused
by impedance mismatching.

Unit
Voltage unit "V" or current unit "A”. When using the current probe, the unit
should be set to "A".

Deskew
Due to the skew between channels, cables, or probes, the delay of signals
passing through different measurement paths may be inconsistent. For
example, two coaxial cables with a 1-inch difference in length could introduce
a skew of more than 100 ps. In some scenarios (e.g. measuring the
setup/hold time between clock and data), it may be necessary to compensate
for the skew between channels.

The method of compensation: Probe the same signal simultaneously using
two channels (including the cables or probes that you intend to use formeasurements) and adjust the deskew parameter of one channel until the
waveforms of the two channels observed on the screen coincide horizontally.

Interpolation -- At small timebase settings, the number of original points on thescreen may be less than the number of display pixels in the grid area, so

88

int.siglent.com

SDS6000A User Manualinterpolation is necessary to display a continuous waveform. For example, at 1
ns/div timebase and 5 GSa/s sample rate, the number of original points is 50,
but the grid area includes 1000 horizontal pixels. In this case, the oscilloscopeneeds to interpolate the original points by 20.


X: Linear interpolation, the simplest way of interpolation, connects two
original points with a straight line.

Sinc: Sin(x)/x interpolation, the original point is interpolated according to
the Nyquist reconstruction formula, which has a good time-domain recovery
effect for a sine wave. But for step signals/fast rise times, it will introduce
false overshoot due to the Gibbs phenomenon.

X Interpolation

Sinc Interpolation

Acq mode: "Fast" is the default setting. The SDS6000A provides a very highwaveform update rate in fast mode. "Slow" mode will slow down the waveform
update on purpose.

Memory Depth: The memory depth that can be supported. According to theformula "acquisition time = sample points x sample interval", setting a larger
memory depth can achieve a higher sample rate for a given time base, but more
samples require more processing time, degrading the waveform update rate.

The memory depth supported by the SDS6000A is listed in the following table:

13.2.2 Acquisition
The acquisition mode is used to determine how to acquire and process thesignal.

Normal: The oscilloscope samples the signal with equal time intervals. For90

int.siglent.com

SDS6000A User Manualmost waveforms, the best display effect can be obtained using this mode.

Peak: Peak detect mode. The oscilloscope acquires the maximum andminimum values of the signal within the sample interval so the peak (maximumminimum) in the interval is obtained. This mode is effective to observeoccasional narrow pulses or spurs with a low sample rate, but the noise
displayed is larger. In peak mode, the oscilloscope will display all pulses with apulse width longer than 200 ps.

In the following example, a narrow pulse sequence with a pulse width of 3.4 ns
and a period of 200 Hz is sampled at a 5 MSa/s sample rate in normal modeand peak mode. As we can see, because the sample interval (200 ns) is muchlarger than the pulse width (3.4 ns), it is difficult to capture the narrow pulses innormal mode, but peak mode can ensure that each pulse is captured.

Normal mode

Peak mode

Average: The oscilloscope accumulates multiple waveform frames andcalculates the average as the result. If a stable trigger is available, the resulting
average has a random noise component lower than that of a single-shot record.
The more frames that are accumulated, the lower the noise is. For the
SDS6000A, average processing is implemented by the hardware engine, so it
can still maintain a high waveform update rate when the acquisition mode is set

to average.

You can reset the accumulated average by pushing the Clear Sweeps buttonon the front panel.

Normal mode

Average mode（128）Note: Average acquisition is only valid for periodic signals, and it isimportant to ensure that the waveform is triggering stably when using
average mode.

Hi-Res: High-resolution mode. The oscilloscope filters the sample, which
rejects noise in the high-frequency domain, so the signal-to-noise ratio (SNR)
is improved. As a result, the resolution of the oscilloscope is enhanced. For the
SDS6000A, Hi-Res processing is implemented by the hardware engine, so it
can still maintain a high waveform update rate when the acquisition mode is HiRes.

Normal mode

92

Hi-Res mode (3-bit)

int.siglent.com

SDS6000A User Manual

Hi-Res acquisition does not require the signal to be periodic, nor does it require
stable triggering, but due to the digital filtering, the system bandwidth of theoscilloscope will degrade in Hi-Res mode. The higher the enhanced bits, thelower the bandwidth. The following table shows the relationship between HiRes bits and bandwidth:

13.2.3 Memory Management
Memory Management controls how the instrument stores the acquired samples.

Auto: The default acquisition setting. After setting the maximum memory in the
Auto mode, the oscilloscope automatically adjusts the sample rate and memory
depth according to the time base. The adjustment principle is to follow theformula:Sample rate = number of samples/time of acquisition
Where the time of acquisition is the time corresponding to the full display (i.e.
10 horizontal divisions).

int.siglent.com

93

SDS6000A User Manual

Note: The maximum memory here is the upper limit of the memory space
allocated by the oscilloscope. The actual sample points are related to thecurrent time base and may be less than memory depth. The actual sample
points information can be obtained in the timebase descriptor box (see thesection "Timebase and Trigger" for details).

Fixed Sample Rate: The sample rate is fixed as set, and the oscilloscope
automatically adjusts memory depth according to the time base. The time ofacquisition is the time corresponding to the full display (i.e. 10 horizontal
divisions).

Fixed Memory: The memory depth is fixed as set, and the oscilloscope
automatically adjusts the sample rate according to the time base. With a small
time scale (such as 1 ns/div) the memory depth is beyond the time of the full
display, so it needs to zoom out the acquired frame for viewing the complete
frame in Stop mode.

Note: In Run status, the scope only processes the data on the display,which means measure, math, decode, search, etc. only analyze the dataon the display. This is identical to the "Auto" memory management mode.

13.2.4 Roll Mode
Press the Roll button on the front panel to enter roll mode. In this mode, thewaveform moves across the screen from right to left, similar to a strip chart
recorder. The horizontal delay control of the waveform will be disabled whenroll mode is active. It only operates at timebase values of 50 ms/div and above.

If you would like to stop the display in Roll mode, press the Run/Stop button.
To clear the display and restart an acquisition in Roll mode, press the Run/Stopbutton again.

94

int.siglent.com

SDS6000A User Manual

Note: Zoom is only supported after Stop in Roll mode.

13.2.5 Sequence
Touch Acquire>Sequence to recall sequence dialog box.
A. Turn on or off sequence
B. Set the segment

Sequence mode is a fast acquisition mode, which divides the memory depth
into multiple segments (up to 80,000), each of which stores a single shot. In
sequence mode, the oscilloscope only acquires and stores data without
processing and displaying, until the specified segments are acquired. As aresult, the dead time between trigger events is minimized, thus greatly
improving the waveform update rate. If sequence mode is enabled, the display
will not update until all of the sequences have been acquired. The SDS6000A
can achieve a minimum 1.3 us trigger interval in Sequence mode,
corresponding to a waveform update rate of 750,000 wfm/s.

After the acquisition is finished, the oscilloscope will map all the segments
together to the screen. If you need to view and analyze each frame separately,
history mode will help (see the section "History" for details). History mode
provides timestamp labels for each segment.

int.siglent.com

95

SDS6000A User Manual

In addition to minimizing the dead time, another advantage of Sequence modeis that it can capture and record rare events over long periods. The oscilloscope
can capture multiple events that satisfy the trigger conditions, ignoring theperiods of no interest between adjacent events, thus maximizing the use of
waveform memory. You can use the full accuracy of the acquisition timebase
to measure selected segments.

13.2.6 ESR
Each channel of the SIGLENT SDS6000A Oscilloscope employs a 5 GSa/sanalog-to-digital-converter (ADC). After each ADC, a 2x interpolation process
is applied that provides a 10 GSa/s ESR option for the users. The data flow andcorresponding spectrum are shown in the figure below:

ESR data flow in the SDS6000A

The 2x interpolation implemented is a classic sinx/x up-sampling processed bya high-speed Field Programmable Gate Array (FPGA) in real-time. The
following figure shows the frequency response of the Finite Impulse Response(FIR) digital filter used in the interpolation. From the frequency response we cansee it has no attenuation at fmax = 2 GHz, and ~70 dB attenuation at 5 GHz –fmax = 3 GHz, which provides enough alias suppression for signals in theoperating bandwidth. The aliasing associated with signals above 2 GHz is
minimized by the fast roll-off of the analog front end.

Higher measurement precision
The ADC sample rate to bandwidth ratio in the SDS6000A is 2.5:1. That means
for a 2 GHz input there are 2.5 samples/period. Without any extra interpolation,
the measurements on vertical waveform elements such as Maximum, Minimum,and Peak-peak will introduce considerable error at high-frequency input. The
figure below shows an example in which a 500 MHz signal is sampled at 5
GSa/s:

SDS6000A User Manual

Interpolation can significantly reduce this kind of error. Below is the same signal
with an identical sample rate but followed by the 2x interpolation technique.
From this figure, we can see points inserted between the raw data in the
top/base area are closer to the real top/base of the analog input, which reduces
the error on measurement.

Error on vertical measurement after 2x interpolation

Higher Hi-Res bandwidthHigh resolution acquisition in the SDS6000A enhances the vertical resolution
but doing so results in a decrease in the available bandwidth. The higher the
resolution, the lower the bandwidth. The bandwidth as a function of resolution
and sample rate is shown in the table below:

15 Trigger
Overview
The oscilloscope only acquires waveforms of interest (i.e. the ones that satisfy
the trigger condition) and aligns all trigger events at the trigger position to forma stable waveform display. The trigger is one of the most important features ofan oscilloscope since we can only analyze a signal that we can trigger reliably
and stably.

The trigger position is movable on the display. The following diagram shows the
structure of the acquisition memory. The acquisition memory is divided into pretrigger and post-trigger buffers and the boundary between them is the trigger
position. Before the trigger event arrives, the oscilloscope fills the pre-trigger
buffer first, and then continuously updates it in FIFO mode until the trigger event
arrives. After the trigger event, the data fills the post-trigger buffer. When the
post-trigger buffer is full, an acquisition is completed.
Trigger Event

Below is the definition of the states in the process of filling the acquisition

Ready: The pre-trigger buffer is full, and the oscilloscope is waiting for thetrigger event.
Trig’d: A trigger event is detected and the oscilloscope starts to fill the posttrigger buffer.

Trigger settings should be based on the features of the input signal. For
example, a sine wave with a repeatable period can be triggered on the risingedge; for capturing hazards in a combinational logic circuit, the pulse trigger
can be set. You need to have some knowledge of the signal-under-test to
quickly capture the desired waveform.

with a positive slope crosses the trigger level, the trigger condition is satisfied
and the time point the signal crosses the level is the trigger position.

In some special triggers, the system will automatically set the trigger level, suchas using AC Line as the trigger source.

Trigger Mode
The trigger mode determines how the oscilloscope acquires waveforms.

15.5.5 Video Trigger
Video trigger can be used to capture the complicated waveforms of moststandard analog video signals. The trigger circuitry detects the vertical andhorizontal interval of the waveform and produces a trigger based on the video
trigger settings you have selected. The SDS6000A supports standard video
signals for NTSC (National Television Standards Committee), PAL (Phase
Alternating Line), HDTV (High Definition Television), and a custom video signal
trigger.

Source, standard, and synchronization mode can be set in the video trigger
dialog box. When the synchronization mode is "Select", line and field can be
specified.

Touch the Standard and select the video standard. The SDS6000A supports
the following video standards:

15.5.6 Window Trigger
The window trigger is similar to the edge trigger, except that it provides an upper
and a lower trigger level. The instrument triggers when the input signal passes
through the upper level or the lower level.

There are two kinds of window types: Absolute and Relative. They havedifferent trigger level adjustment methods. Under the Absolute window type, thelower and the upper trigger levels can be adjusted separately. The relative
window provides adjustment for the Center value to set the window center andthe Delta value to set the window range. In this mode, the lower and the upper
trigger levels always move together.



If the lower and the upper trigger levels are both within the waveform
amplitude range, the oscilloscope will trigger on both rising and fallingint.siglent.com

125



If the upper trigger level is within the waveform amplitude range while
the lower trigger level is out of the waveform amplitude range, theoscilloscope will trigger on the rising edge only.



If the lower trigger level is within the waveform amplitude range while
the upper trigger level is out of the waveform amplitude range, theoscilloscope will trigger on the falling edge only.

To set window trigger via the Absolute window type
Refer to "Adjust Upper/Lower Level" in the section "Slope Trigger".

To set window trigger via the Relative window type
When the window trigger type is set to"Relative", touch the trigger descriptor
box. The pop-up menu will show twouser-defined parameters: “Level +/Delta" and "Level Center".

The above two parameters can be set
in the following two ways:
1. Select the parameter in the Level +/-Delta area of the quick menu, then
set the parameter value by the virtual keypad or the Level knob on thefront panel. To set the center level is similar.
2. Directly use the Level knob on the front panel. Press the knob to switch
between “Level +/-Delta" and "Center Level", and rotate it to set values.

Holdoff
Holdoff is an additional condition for triggers and can be used to stabilize thetriggering of complex waveforms (such as a pulse series). It can be set to a timeor number of events.

Holdoff by Time
Holdoff time is the amount of time that the oscilloscope waits before re-arming
the trigger circuitry. The oscilloscope will not trigger until the holdoff time expires.

Use the holdoff to trigger on repetitive waveforms that have multiple edges (orother events) between waveform repetitions. You can also use holdoff to trigger
on the first edge of a burst when you know the minimum time between bursts.

For example, to achieve a stable trigger on the repetitive pulses shown in the
figure below set the holdoff time (t) to 200ns<t<600ns.

Holdoff by Event
The Holdoff event sets the number of events that the oscilloscope counts before
re-arming the trigger circuitry. The oscilloscope will not trigger until the counterthat tracks holdoff events reaches the set value. In the following figure, theholdoff event is set to 3, and the signal is triggered on the fourth edge.

Acq Start-- The initial position of holdoff is the first time point satisfying thetrigger condition. In the example above, each holdoff starts from the first risingedge of the pulse sequence.

Last Trig Time--The initial position of holdoff is the time of the last trigger. In
the example above, the last trigger position is at the second rising edge of thepulse sequence and the second holdoff starts from that point.

Trigger Coupling
The coupling setting of a trigger is only valid when the trigger source is C1~C4,
EXT, or EXT/5.


DC: All of the signal’s frequency components are coupled to the trigger
circuit for high-frequency bursts or where the use of AC coupling would shift
the effective trigger level.



AC: The signal is capacitively coupled. DC levels are rejected. See thedatasheet for details of the cut-off frequency.



HFR: Signals are DC coupled to the trigger circuit and a low-pass filter
network attenuates high frequencies (used for triggering on low
frequencies). See the datasheet for details of the cut-off frequency.



LFR: The signal is coupled through a capacitive high-pass filter network,
DC is rejected and low frequencies are attenuated. For stable triggering on
medium to high-frequency signals. See the datasheet for details of the cutoff frequency.

Noise Reject
Noise Reject adds additional hysteresis to the trigger circuitry. By increasing
the trigger hysteresis, the noise immunity becomes better but the trigger
sensitivity degrades.

SPI Trigger and Serial DecodeThis section covers triggering and decoding SPI signals. Please read thefollowing for more details: "SPI Signal Settings", "SPI Trigger" and "SPI Serial
Decode".

16.3.1 SPI Signal Settings
Connect the CLK, MOSI, MISO, and CS signals to the oscilloscope and set the
mapping relation between channels and signals. Then set the threshold level ofeach signal. The process of specifying the source and threshold is similar to"I2C Signal Settings".

CLK
In addition to specifying the source and the threshold level, for the CLK signal,
it is also necessary to specify the Edge Select.


Rising–Data latched on the rising edge of the clock.



Falling–Data latched on the falling edge of the clock.

The user can select the edge according to the actual phase relationshipbetween the clock and the data of the SPI bus. Referring to the following figure,when the falling edge of the clock is aligned with the data, the rising edge isselected to latch the data. When the rising edge of the clock is aligned with thedata, the falling edge is selected to latch the data.

SDS6000A User ManualCS
The CS signal should be set to correct CS Type, including CS, ~CS, and Clock
Timeout.
CS – Active high. The CS signal needs a complete rising edge in the screen
to be regarded as active.

~CS – Active low. The ~CS signal needs a complete falling edge in thescreen to be regarded as active.



Clock Timeout – It is not necessary to specify the source and the thresholdlevel for the CS signal. The only parameter for the CS signal is the timeout
Limit, which is the minimum time that the clock signal must be held idle
before the oscilloscope acquires valid data. This setting is suitable for thecase where the CS signal is not connected, or the number of oscilloscope
channels is insufficient (such as two-channel oscilloscopes).

The method of copying settings is the same as I2C signal settings. See "I2C
Signal Settings" for details.

SDS6000A User Manual

Connect the data, CLK, and ~CS signals of an SPI bus respectively to C1, C2,
and C3. Data width = 8-bit, Bit order = MSB, CS polarity = active low, and 12
data bytes are transmitted in one frame.

In the SPI trigger signal menu, set the source and threshold of CLK, MISO, andCS signals, then copy the trigger settings to decoding. Adjust the timebase, sothat there is a falling edge on the CS signal shown on the screen:

When the CS type is set to Clock Timeout, turn on Cursor, measure the clockidle time between frames as 150 us, and measure the interval between clock
pulses as 1.28 us, then set the timeout to a value between 1.28 us and 150 us.
In this example it is set to 5 us:160

18 Measurement
Overview
The SDS6000A features a strong automatic measurement list. These
parameters can be automatically measured without cursors and include
common measurements such as rise time, fall time, peak-peak, and period. The
SDS6000A can also measure multiple channels at the same time, showing up
to 6 parameter measurements with statistics while in the M1 display mode andup to 12 parameters in the M2 mode. If you wish to view more parameters on a
specified channel, then the "Simple" mode can be employed. For measuring
waveform of interest in a time gate, the "Gate" function is suggested.

Some parameter measurements (such as the mean) may be a value generated
by all the data in a frame. Some parameter measurements (such as period)
accumulate all measurements in a frame, but the displayed value is always thefirst value. If you want to know the distribution of multiple parameters in one
frame, you should use the statistics function.

The hardware frequency counter is a stand-alone, hardware-based frequency
measurement function. Differing from the “Frequency” parameter (see section“Horizontal Measurement”) which is measured by software, the hardware
frequency counter directly uses the trigger signal as the input of a hardware
counter, which yields 7-digit frequency measurement accuracy. The accuracyof the “Frequency” parameter measured by software is relative to the sample
rate. The lower the sample rate, the worse the accuracy. In situations where
the sample rate is less than 2 times the input frequency, the results will beincorrect. The hardware frequency counter does not have this limitation. Its

19.3.1 Differential
The differential (d/dt) operator is used to calculate the derivative of the selectedsource. It is always used to measure the instantaneous slope of the waveform,
such as the slew rate of an operational amplifier.
The differential equation is:di =y (i + dx) - y(i)dxWhere:
d = Differential result
y = Values of source datai = Data point index
dx = Differential interval

The range of “dx” in the d/dt menu is 4~ number of samples pts.

Note: Differentiation is sensitive to noise. It is helpful to set theacquisition mode to “Average” or “Hi-Res” to help minimize the visible
effects of additional noise.

19.3.2 Integral
Integral operation integrates the waveforms on the screen or within thespecified gate.

Setting Offset in the integral menu provides an approach to correct the DC
offset of the source. Small DC offsets in the input signal (or even small offset
errors of the oscilloscope itself) may cause the integral output waveform to

Integral without Offset

Integral with Offset

In addition, the integral operation can be performed within a specified gate.
Touch Gate area in the math dialog box, and enable the Gate function, then set
Gate A and Gate B to define the gate. The setting of the gate cursors is similar
to that of normal cursors. See "Select and Move Cursors" for details.

19.3.3 Square RootSquare root （√） calculates the square root of the selected source. If the
waveform value is negative (the waveform is below the ground level), the result

19.3.4 Absolute
Absolute（|x|）calculates the absolute value of the selected trace.

19.3.5 Sign
In mathematics, the sign function or signum function (from signum, Latin for"sign") is an odd mathematical function that extracts the sign of a real number.

SDS6000A User Manual

The sign function of a real number x is defined as follows:Sign(x) = -1

if x < 0,=0

if x = 0,=1

if x > 0.

19.3.6 exp/exp10
The exponential operation includes the exponential operation 𝑒 𝑥 based on
constant e and the exponential operation 10𝑥 based on 10.

For example: y(x) = 𝑒 𝑥 .

Filter
The filter operation in the SDS6000A provides FIR (Finite Impulse Response)
filtering with the following types: Low pass, High pass, Bandpass, and Band
Reject. The filters have up to 200 taps which can reach roll-off as fast as 0.01*fs.
Users just need to set the filter type and corner frequency(s), then the
instrument will automatically calculate the coefficients needed for the filtering.

A. Choose to let the scope set the sample rate
automatically according to the filter setting
or not. See below for details
B. Filter type: Low pass, High pass, Bandpass,and Band Reject
C. Corner frequency. For Bandpass and Band
Reject there are two corner frequencies,
separately named Lower Frequency andUpper Frequency. The attenuation at thecorner frequency is around 3 dB

Adapt Sample Rate
Unlike an ideal “brick wall” filter, the actual FIR filters have their roll-off from thepassband to the stopband because of the limited number of taps. The 200-tap
FIRs applied in the SDS6000A provide roll-off as fast as 0.01*fs (where fs is the
sample rate), this means some limitations in the setting of corner frequency ata specified sample rate. The figures below show the limitations in detail:int.siglent.com

flBand reject

Take a Low pass filter as an example. It requires that the corner frequency (fc)is not less than 0.01*fs (i.e. fc≥0.01*fs), and the 0.01*fs wide roll-off does notexceed the 1st Nyquist zone (i.e. (fs/2)-fc≥0.01fs). If fs = 5 GSa/s, then the legal
range of the corner frequency (fc) is 50 MHz~2450 MHz.

If the expected fc is out of the legal range at some sample rate, then the sample
rate needs to be changed. For instance, when fs = 5 GSa/s, the setting fc=10
MHz is illegal, so we must lower down fs to 1 GSa/s to satisfy the limitation(fc≥0.01*fs).

244

int.siglent.com

SDS6000A User Manual

Professional users who have prior knowledge of FIR filters and are familiar withthe operation of this instrument are encouraged to change the sample rate forthe corner frequency of interest. Otherwise, we recommend using the “Adapt
Sample Rate” option. In this mode, the scope forces the Memory Management
Mode to be “Fixed Sample Rate” and automatically adjusts the sample rate toadapt to the corner frequency setting. For details of the Memory Management
Mode refer to the section “Memory Management”.

Note: Be aware that when the corner frequency is set very low thesample rate may not satisfy the Nyquist Theorem (i.e. fs is no longer
greater than or equal to twice the highest frequency of the input). Keepthe sample rate reasonable at all times.

Frequency Analysis
The result of FFT (Fast Fourier Transform) calculations is the frequency
spectrum of the source signal. The horizontal axis of the FFT display is labeledusing frequency (Hz) units instead of time (seconds). In addition, the verticalaxis provides the option of logarithmic scaling (dBVrms/dBArms or dBm).

the FFT takes the number which is an integer power of 2 closest to N.
In this case, FFT sample rate = sample rate in the time domain.
✓ When N is greater than 2 Mpts, FFT first decimates N by D and thentakes the first 2 Mpts for the calculation. In this case, FFT sample rate
= sample rate in time domain/D.
For example, in the case of sample rate in the time domain is 5 GSa/sand the number of samples is 5 Mpts, the FFT first decimates the
samples by 2, to 2.5 Mpts, and then takes the first 2 Mpts to calculate
the spectrum. In this example, FFT sample rate = 5 GSa/s ÷ 2 = 2.5

IEC 61000-3-2 is an international standard that limits mains voltage distortionby prescribing the maximum value for harmonic currents from the second
harmonic up to and including the 40th harmonic current. There are 4 different
classes in the EN 61000-3-2 that have different limit values:Class A: Balanced 3-phase equipment, household appliances excluding
equipment identified as class D, tools, excluding portable tools, dimmers
for incandescent lamps, audio equipment, and all other equipment, exceptthat stated in one of the following classes.

Class B: Portable tools, arc welding equipment which is not professional
equipment

Class C: Lighting equipment.

Class D: PC, PC monitors, radio, or TV receivers. Input power P ≤ 600 W.I

Parameter Description
For the first 40 harmonics, the following values are displayed:
Measured Value (RMS) -- The measured value displayed in the unit specified
by the harmonic unit parameter
Limit Value (RMS) -- Limits specified by the selected standard
Margin (%) --The margin specified by selected standard parameters. The
margin value is (standard value - measured value) / standard value * 100%
Pass/Fail State -- Determine whether the measured value is passed or failed
according to the selected standard. The rows in the table or the bars in the bar
chart are rendered in different colors based on the pass / fail state. When thevalue is greater than 85% of the limit but less than 100% of the limit, it is defined
as a critical state.

dynamic range limitation when trying to measure weak voltage and (or) current
in the presence of relatively large switching voltage and (or) current.

SOA
The safe operating area (SOA) of MOSFETs defines the voltage, current, andpower consumption conditions over which the device can be expected tooperate without self-damage. The oscilloscope can automatically generate the
SOA according to the Voltage Limit, Current Limit, and Power Limit parameters
set in the Config menu, and judge if the stress on the MOSFET is beyond the
SOA or not. This helps the designers to quickly find a problem or latent risk inthe circuit.

29 Bode Plot
Overview
The SDS6000A supports an automatic Bode plot function. This function
provides a frequency response curve of the device-under-test as well as theinterface for output sweep parameter control and data display settings. At thistime, either the SIGLENT SAG1021I arbitrary waveform generator or one of a
SIGLENT SDG series arbitrary function generators are supported. During thesweep, the oscilloscope configures the generator output frequency andamplitude and then compares the input signal to the output of the DUT. Gain(G) and phase (P) are measured at each frequency and plotted on thefrequency response Bode plot. When the loop response analysis is complete,
you can move the markers on the chart to see the gain and phase values
measured at each frequency point. You can also adjust the scale and offset
settings for the amplitude and phase plots.

DCD

Duty cycle distortion (DCD) is the difference between mean TIE
for rising edges and mean TIE for falling edges. Asymmetricalrise-time vs. fall-time and non-optimal choice of decisionthreshold will cause DCD.

DDJ

Data-dependent jitter (DDJ) has several discrete line
distributions, main caused by ISI, the physical/electrical effect.
There will be different zero-crossing positions, due totransmission line effects like reflections and the step responseof the system.

PJ

Periodic jitter (PJ) is mainly caused by the periodic signal
interference on the board, including power supply ripple, clock
crosstalk, etc. Periodic interference can directly cause phasemodulation of the observed signal.

System Effect on Jitter Measure
The system's influence on the jitter measurement must be taken into
consideration. It is important to evaluate the degree of error introduced in thejitter measurement according to the specifications of the measurement systemitself. The methods applied to the measuring process also play an importantrole in the jitter measurement.

The system error formula of oscilloscope jitter measurement is as follows:2

 Noise 2
err =  + Jitter Sample Clock Slew rate Sample clock jitter and noise in the formula are possible from the oscilloscope
itself. Besides, the slew rate of the signal under test also is related to the systemerror according to the formula. The slew rate is inversely proportional to theerror when the noise value does not change. This indicates that we should use
signals with edges as fast as possible during jitter testing, and keep the signal
at full scale of the oscilloscope by adjusting the vertical scale.

int.siglent.com

357

SDS6000A User Manual

OVP
When OVP is enabled, the output will be turned off automatically once theprotection condition is met. The protection condition is when the absolutevalue on the output port is higher than 4 V ± 0.5 V. At the same time, awarning message is displayed.

Sync Output
When the Sync Output is turned on, the Aux In/Out port of AWG outputs a
CMOS signal with the same frequency as the basic waveform (except Noiseand DC) and arbitrary waveform. The maximum supported frequency is 10
MHz.

Zero Adjust
The output zero error of the AWG can be calibrated by using auto mode or
manual mode. The object of the Zero Adjust is: when AWG outputs 0 V DC
signal, the measured mean value of the corresponding channel is within ±1mV.

Auto Steps: In this mode, the adjustment can only be performed with CH1of the oscilloscope. Connect the output of AWG to CH1 of the oscilloscope,press Auto, and the AWG will start to automatically adjust. The scope will
display “Zero adjust completed!” when the adjustment is done.



Manual Steps: The AWG can be manually calibrated through any
channel on the oscilloscope. Take CH2 as an example:
1. Connect the output of AWG to CH2, open CH2, set it to DC coupling,turn on the bandwidth limit, and set the probe attenuation to 1X.

358

To Default Key
The oscilloscope provides two options for the default setting. When the
Default Type is set to “Factory”, the factory default setting will be recalled bypressing the Default button on the front panel; When the Default Type is set to362

int.siglent.com

SDS6000A User Manual“Current”, the last setting saved by the “To Default Key” operation will berecalled by pressing the Default button on the front panel.

FileConverter
The mini tool is used to convert stored binary files to CSV format for viewing
with a spreadsheet program. This is ideal when collecting large datasets. Fora waveform frame with deep memory such as 250 Mpts, saving directly as a
CSV file will take a long time and will occupy a large amount of memory on a
USB storage device. It’s recommended to save the data as a binary file andthen convert it to a CSV file on a computer.

37 Troubleshooting
The commonly encountered failures and their solutions are listed below.
When you encounter those problems, please solve them using thecorresponding steps. If the problem remains, please contact SIGLENT assoon as possible.

1. The screen is still dark (no display) after power on:
1) Check whether the power is correctly connected.
2) Check whether the power switch is on.
3) Check whether the fuse is burned out. If the fuse needs to bechanged, please contact SIGLENT timely and return the instrument
to the factory for replacement by the maintenance personnel
authorized by SIGLENT.
4) Restart the instrument after finishing the above inspections.
5) If it still does not work correctly, please contact SIGLENT.

2. The signal is sampled but no waveform of the signal is displayed:
1) Check whether the probe is correctly connected to the signal
connecting wire.
2) Check whether the signal connecting wire is correctly connected to
the BNC (namely channel connector).
3) Check whether the probe is correctly connected to the item to betested.
4) Check whether there are signals generated from the item to betested.

int.siglent.com

391

SDS6000A User Manual

5) Resample the signal.

3. The tested voltage amplitude is greater or lower than the actual value(Note that this problem usually occurs when the probe is used):
1) Check whether the attenuation coefficient of the channel complies
with the attenuation ratio of the physical probe.
2) Disconnect the oscilloscope from the external signal and do a selfcal.

4. There is a waveform display but not stable:
1) Check the trigger signal source: check whether the source item atthe trigger panel complies with the signal channel used.
2) Check whether it is a "false wave”: when the signal frequency isvery large (more than half of the sample rate), it is easy to appear
as a "false wave". At this point, a small time base should be set tomake the sample rate more than 2 times the signal frequency.
3) Check the trigger type: general signals should use the “Edge”
trigger and video signals should use the “Video” trigger. Only when
the proper trigger type is used, can the waveform be displayed
stably.
4) Change the trigger holdoff setting.

5. No display after pressing Run/Stop:
Check whether the mode at the trigger panel (TRIGGER) is on “Normal”
or “Single” and whether the trigger level exceeds the waveform range.
If yes, set the trigger level to the middle or set the mode to “Auto”.

6. The touch screen does not respond to touch operation:
1) Check whether the Touch button backlight on the front panel islighted up. If not, the touch screen is not turned on. Press the button
to enable the touch screen
2) Restart the instrument.

7. The USB storage device cannot be recognized:
1) Check whether the USB storage device can work normally.
2) Make sure whether the USB interface can work normally.
3) Make sure that the USB storage device being used is flash storage
type. This oscilloscope does not support hardware storage type.
4) Make sure that the U disk system format is FAT32.
5) Restart the instrument and then insert the USB storage device tocheck it.
6) If the USB storage device still cannot be used normally, pleasecontact SIGLENT.
