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
