MEASure Subsystem
MEASure Subsyste m
MEASure subsystem commands apply only to measurements found i n
the
MEASURE
menu . These commands primarily control measurement s
in single mode.
Use the single commands in this subsystem to quickly mak e
measurements using the factory default instrument settings .
MEASure commands stop the present measurement and set up th e
instrument for the specified measurement using the factory default
values. Other SCPI communication is blocked until the measurement i s
complete. After the data is valid, the scalar result is returned for th e
specified measurement .
If you need to change some of the measurement parameters from th e
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 an d
: FETCh? commands to initiate the measurement and query the results .
Measure Main, Lower, and Upper Channel Powe r
: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 curren t
amplitude units, and the lower and upper channe l
results are always returned in dB . The results are
returned in a comma-separated list.
Measure Main Channel Powe r
:MEASure :ACPower :MAIN ?
This command returns the value of main channel power in the current
amplitude units.
Front Panel
Access : MEASURE, ACP
Measure Lower Channel Power
:MEASure :ACPower :LOWer ?
This command returns the value of the lower channel power relative t o
the main channel power, in dB.
