Description
For simulated modules, sets the type of modulation applied to the simulated input signal. Selections are NRZ (which is the default format) and PAM4, PAM6, and PAM8.
Example Command Sequence
:SOURce:FORMat PAM4 :SYSTem:AUToscale *OPC?
Requires FlexDCA revision A.04.50 and above. Revision a.08.30 for PAM6 and PAM8.

Selecting AWG Channels
When sending a :SOURce subsystem command to an AWG, the method used to specify the AWG's channel may look confusing at first glance. This is because, the AWG's front-panel channels are labeled 1, 2, 3, and 4, but FlexDCA identifies channels with letters (A, B, C, or D). As a result, you must convert the AWG's channel number to an equivalent FlexDCA letter. For example, to enable channel 3 of an AWG that is installed in FlexDCA's slot 5 use the following command: :SOURce5C:OENable ON.
