[<expected_value>[,<resolution>[,<source list>]]]
This command sets the specified window's measurement function to
difference mode with relative mode off, aborts 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.
INITiate:CONTinuous must be set to OFF on both channels,
Note
otherwise error -213, "INIT ignored" occurs. If TRIGger:SOURce
is set to BUS on either channel, error -214, "Trigger deadlock"
occurs.
