[<expected_value>[,<resolution>[,<source list>]]]
This command sets the specified window's measurement function to single
channel 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/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
