READ Subsystem

READ subsystem commands apply only to measurements found in the
menu. READ commands do not preset the measurement to
MEASURE
the factory default values, as do the MEASurement subsystem
commands. Instead, they use settings from the last measurement.
Read commands initiate the measurement and put valid data into the
output buffer. Other SCPI communication is blocked until the
measurement is complete. However, if a measurement other than the
current one is specified, the instrument will switch to that
measurement before it initiates the measurement and returns results.

Measure Main, Lower, and Upper Channel Power

:READ: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

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

Measure Lower Channel Power

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

Measure Upper Channel Power

:READ:ACPower:UPPer?
This command returns the value of the upper channel power relative to
the main channel power, in dB.
