[<expected_value>[,<resolution>[,<source list>]]]
This command sets the specified window's measurement function to ratio
mode with relative mode on, aborts then initiates both channel A and B,
calculates the ratio measurement result using the new sensor data and
places the result 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.
INITiate:CONTinuous must be set to OFF on both channels,
Note
otherwise error -213, "INIT ignored" occurs. If TRIGger:SOURce
is set to BUS on either channel, error -214, "Trigger deadlock"
occurs.
