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

READ[1]|2|3|4[:SCALar][:POWer:AC]:DIFFerence:
RELative? [<expected_value>[,<resolution>[,<source list>]]]
This command sets the specified window's measurement function to difference
mode with relative mode on, aborts then initiates both Channel A and B,
calculates the difference measurement result and places the result on the bus.
The result is a ratio based measurement and is expressed in the units defined by
UNIT[1]|2|3|4:POWer:RATio. The relative value used is that set by the
CALCulate:RELative:MAGNitude:AUTO command.
IINITiate:CONTinuous must be set to OFF on both channels, otherwise error
NOTE
–213, "INIT ignored" occurs. If TRIGger:SOURce is set to BUS on either channel,
error –214, "Trigger deadlock" occurs.
