2 MEASurement Commands
READ[1]|2|3|4[:SCALar][:POWer:AC]:RATio?
[<expected_value>[,<resolution>[,<source list>]]]
This command sets the specified window's measurement function to ratio mode
with relative mode off, aborts then initiates both Channel A and B, calculates the
ratio measurement result 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.
INITiate:CONTinuous must be set to OFF on both channels, otherwise error
NOTE
–213, "INIT ignored" occurs. If TRIGger:SOURce is set to BUS on either channel,
error –214, "Trigger deadlock" occurs.
