FETCh[1]|2|3|4[:SCALar][:POWer:AC]:RATio?

[<expected_value>[,<resolution>[,<source list>]]]
This command sets the specified window's measurement function to power ratio
with relative mode off, 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.

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.
This channel list specifies the channels used to
calculate the ratio.
If unspecified and the current window setup is a ratio
measurement then this ratio setup is used, otherwise it
defaults to channel A/B (E4417A) or A/A (E4416A).
