FETCh[1]|2|3|4[:SCALar][:POWer:AC]:DIFFerence?
[<expected_value>[,<resolution>[,<source list>]]]
This command sets the specified window's measurement function to power
difference with relative mode off, recalculates the measurement and
places the results on the bus. The result is a power based measurement
and is expressed in the units defined by UNIT[1]|2|3|4:POWer.

DEF
Description/Default
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.
