MEASurement Subsystem

MEASurement Subsystem
MEASurement subsystem commands apply only to measurements
found in the
MEASURE
measurements in single mode.
Use the single commands in this subsystem to quickly make
measurements using the factory default instrument settings.
MEASure commands stop the present measurement and set up the
instrument for the specified measurement using the factory default
values. Other SCPI communication is blocked until the measurement is
complete. After the data is valid, the scalar result is returned for the
specified measurement.
If you need to change some of the measurement parameters from the
factory default settings, set up the measurement with the CONFigure
command. Use the commands in the SENSe: subsystem to change the
settings. Then use the :READ? command, or the :INITiate and
:FETCh? commands to initiate the measurement and query the results.

Measure Main, Lower, and Upper Channel Power

:MEASure:ACPower?
This command returns scalar results of main channel power, lower
channel power (relative), and upper channel power (relative).
Remarks: The main channel power is returned in the current
amplitude units, and the lower and upper channel
results are always returned in dB. The results are
returned in a comma-separated list.

Measure Main Channel Power

:MEASure:ACPower:MAIN?
This command returns the value of main channel power in the current
amplitude units.

Measure Lower Channel Power

:MEASure:ACPower:LOWer?
This command returns the value of the lower channel power relative to
the main channel power, in dB.
