10MHz INThe [10MHz IN] and [10MHz OUT] connectors are commonly used to establish synchronization
between multiple instruments. The RF source can use an internal reference source or an externalreference source.
If the instrument detects that there is a valid 10MHz IN signal at the [10MHz IN] connector, it will use
it as an external reference source. At this point the user interface status bar shows "Ext Ref". Whenan external reference is lost, exceeded, or disconnected, the instrument automatically switches tothe internal reference, and the screen status bar will no longer display "Ext Ref".
7.

10MHz OUT

The [10MHz IN] and [10MHz OUT] connectors are commonly used to establish synchronization
between multiple instruments. The RF source can use an internal reference source or an externalreference source.
If the instrument uses an internal reference source, the [10MHz OUT] connector can output a
10MHz clock signal generated by the instrument and can be used to synchronize other devices.
8.

PULSE IN/OUT

The function of the connector is determined by the current mode of pulse modulation.

Flatness

The "Flatness" function adjusts the amplitude at specific frequencies by mathematically adjusting
the output by applying user-defined level correction lists. Correction is performed by theuser-defined table values being added to the output level for the respective RF frequency. Withfrequencies which are not contained in the list, the level correction is determined by interpolation of
the closest correction values.
The flatness correction function can adjust the RF output amplitude corresponding to the frequency
point within the frequency range of the instrument to compensate for losses in the cable, or losses
caused by other equipment.

AM Depth

Set the modulation depth in percent. SelectMOD-> AM -> AM Depth , and then set AM

depth.
⚫

When the “Int” modulation source is selected, the AM modulation depth is set from 0.1% to100%. The relationship between the modulation depth m and the carrier sideband level
difference ΔP is satisfied: ΔP=6.02-20*lg (m)⚫

When the “Ext” modulation source is selected, the actual modulation depth is related to theamplitude of the external input modulation signal:
Modulation depth = amplitude of input signal × external modulation sensitivity
For example, if the modulation depth is set to 100% (AM Sensitivity is 50%/V), the actual
modulation depth will be 100% when the external modulation signal is 2Vpp (offset is 0V) andthe actual modulation depth will be 50% when the external modulation signal is 1Vpp (offset is0V).

⚫

When selecting the “Int+Ext” modulation source, the modulation depth set is the internal source
modulation depth + the external source modulation depth, and the internal source modulation
depth = the external source modulation depth.
Modulation depth = set value × 0.5 + external input signal amplitude × external
modulation sensitivity
For example, if the modulation depth is set to 100%, the modulation depth assigned to theinternal source is 50%, the external source modulation depth is 50%, and the external
modulation sensitivity is 25%/V. If the external modulation signal is 2Vpp (the offset is 0V), thenthe actual modulation depth is 100%.

Level Control

As shown above, the sensor measures a proportional power in defined time intervals, derived from acoupler. It considers optionally the given S-parameters and returns the results to the generator. The
signal generator compares the measured level with the set value and adjusts its output levelaccordingly. This allows you to control the external signal level continuously and reliably reach aconstant input level to the DUT in real time.
In practice, an RF splitter is needed to split the RF signal. One of them is connected to the DUT andthe other is connected to the power meter. The signal source is for acquisition and compensation.
Power compensation can be used to minimize cable losses, the attenuation of passive networks,
and the amplification of the signal by a power amplifier and the frequency response of each device
in the link as the frequency changes.
Note: When the function is turned on, the frequency or level sweep functions will be turned off, andvice versa.

Level Control StateThe default is “Off”.

Measurement

Indicate the current reading of the sensor. Select the unit used for result display. You can change
the unit for the results display: dBm, dBμV, uV, mV, V, nW, uW, mW, W.

Target Level

Specify the nominal level expected at the input of the sensor. The signal generator adjusts theoutput power accordingly, in order to meet the target value at the sensor input, and thus the power
required at the DUT.
The value can be set by the touch screen keyboard or the front panel keypad.

Limit Level

Set an upper limit for the RF output power to protect your DUT from damage due to high input power.
If the input RF signal power exceeds the limit, the set value will not take effect and the source will
pop up a warning message.

Catch Level

The capture range means that if the power sensor reading is within the effective capture range, it isa valid reading and the RF signal will be adjusted and compensated. If the power sensor reading
exceeds this range, the reading will be ignored.
Effective Capture Range = Target Level +/- Catch Range

Build Communications Using Sockets/Telnet

Through the LAN interface, VXI-11, Sockets and Telnet protocols can be used to communicate with
the SSG. VXI-11 is provided in NI-VISA, while Sockets and Telnet are commonly included in theoperating system (OS) of many computers.

Socket LAN is a method used to communicate with the signal generator over the LAN interface
using the Transmission Control Protocol/Internet Protocol (TCP/IP). A socket is a fundamental
technology used for computer networking and allows applications to communicate using standard
mechanisms built into network hardware and operating systems. The method accesses a port on
the signal generator from which bidirectional communication with a network computer can beestablished.

Before you can use sockets LAN, you must select the signal generator’s sockets port number touse:⚫

Standard mode: Available on port 5025. Use this port for programming.

⚫

Telnet mode: The telnet SCPI service is available on port 5024.
