FETCh[1]|2|3|4[:SCALar][:POWer:AC]:DIFFerence:
RELative? [<expected_value>[,<resolution>[,<source list>]]]
This command sets the specified window's measurement function to power
difference with relative mode on, recalculates the measurement and places the
results 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.

Description/Defaul t
The expected power level parameter can be set to DEF or a
numeric value. If a value is entered it should correspond to
that set by CONFigure otherwise an error occurs.The units
of measurement are dBm and W. The default units are defined
by UNIT:POWer.
A numeric value for the resolution. If it is unspecified the
current resolution setting is used. If a value is entered it
should correspond to the current resolution setting otherwise
an error occurs.
