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