READ[1|2][:SCALar][:POWer:AC]:RATio:RELative?
[<expected_value>[,<resolution>[,<source list>]]]
This command is only relevant for the HP E4419B power meter.
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]: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,
otherwise error -213, "INIT ignored" occurs. If TRIGger:SOURce
is set to BUS on either channel, error -214, "Trigger deadlock"
occurs.
