Keysight N8262A Programming Guide

MEASure[1]|2|3|4[:SCALar][:POWer:AC]:DIFFerence?

[<expected_value>[,<resolution>[,<source list>]]]

This command sets the specified window’s measurement function to difference

mode with relative mode off, aborts, configures then initiates both Channel A and

B, calculates the difference measurement result and places the result on the bus.

The result is a power based measurement and is expressed in the units defined by
