FETCh Subsystem

FETCh Subsystem
FETCh subsystem commands apply only to measurements found in the
menu. FETCh commands can only be used as queries.
MEASURE
FETCh commands put valid data into the output buffer, but do not
initiate data acquisition. Use the :INITiate[:IMMediate] command
to acquire data. You can only fetch results from the measurement that
is selected, and when current measurement results are valid.
:FETCh <meas>? will return valid data only when the measurement is
in one of the following states:
idle
initiated
paused

Return Main, Lower, and Upper Channel Power

:FETCh: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.

Return Main Channel Power

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

Return Lower Channel Power

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