Measure[1]|2|3|4[:Scalar][:Power:ac]:Difference? [<Expected_Value>[,<Resolution>[,<Source List>]]] - Keysight N1911A Programming Manual

2 MEASurement Commands
MEASure[1]|2|3|4[:SCALar][:POWer:AC]:DIFFerence?
[<expected_value>[,<resolution>[,<source list>]]]
This command applies to the N1912A power meter only, as it needs two
measurement channels to make sense.
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
UNIT[1]|2|3|4:POWer.
