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

[<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.
