Custom Modulation
The Custom IQ Type: ASK & PSK & QAM waveform setup allows you to configure a frame with multiple data segments and/or idle segments. For each data segment, the modulation type can be further configured using a graphical constellation settings editor.
Use this drop-down menu to select a modulation type from several supported formats. A single data segment using that modulation type appears in the segment list below. Click the cell in the Constellation column to open the Constellation Setting window, providing a graphical display and editing features. Quick setups enable you to configure complex signals for signal generation, equivalent to 89600B VSA setups in signal analysis.
DVB-S2 and DVB-S2X quick setups also add a PLHEADER segment before the data segment, as defined in the standard.

This feature saves the Custom IQ configuration as an 89600B VSA setup file, making it easier to configure complex constellations, such as 256APSK.
VSA software must be version 18.0 or later to support Custom IQ demodulation. If there is more than one data segment configured in the list, they will be saved as VSA setup file with FlexFrame measurement, which was supported from VSA2022 release. Idle segments cannot be saved to the setup file.
Differential and offset modulation types (e.g. pi/4 DQPSK or OQPSK) are found under DigitalDemod on the VSA.
The VSA does not support the APCO25 HDQPSK filter.
FSK configurations are found under DigitalDemod on the VSA.
The VSA does not support ARIB T102 and NXDN filters.
For added convenience, you can save the VSA setup as a quick setup in the VSA's Custom IQ Demod Property window. To do this, recall the PathWave Signal Generation VSA setup file, perform the measurement, and then click . Now, whenever you click , you will find your previously saved setup listed among the other setups provided with the VSA software. Using this method, you no longer need to recall the PathWave Signal Generation VSA setup file each time you want to perform a measurement.
Select the type of Custom IQ.
