Introduction
This programmer manual provides information on how to use commands for remotely controlling the OFDM Signal Modulation plug-in application.
The OFDM Signal Modulation plug-in can be installed in the SourceXpress software application, AWG70000 series instruments, and AWG5200 series instruments.
Communication with the plug-in is through the programmatic interface of these products. Using a single VISA or raw socket session, it is possible to communicate with SourceXpress, AWG70000 series instruments, and AWG5200 series in
