3.7 ACP Measurement
ACP is a measurement of the amount of interference, or power, in an adjacent
frequency channel. The results are displayed as a bar graph or as spectrum data,
with measurement data at specified offsets.
Measurement Commands
The general functionality of "CONFigure" on page 2431, "INITiate" on page 2432,
"FETCh" on page 2432, "MEASure" on page 2434, and "READ" on page 2433 are
described in the section SCPI Operation and Results Query in the topic
Programming the Instrument.
The following measurement commands and queries are used to configure the
measurement:
:INITiate:ACPower
Initiates a trigger cycle for the ACPower measurement,
but does not return any data. You must then use
:FETC:ACP[n]? to retrieve data
Does not change any measurement settings
:CONFigure?
Returns the long form name of current measurement, in
this case, ACPower
:CONFigure:ACPower
Selects ACP measurement with Meas Setup settings in
preset state – same as "Meas Preset" on page 905
:CONFigure:ACPower:NDEFault
Selects ACP measurement without affecting settings
The following queries are used to retrieve the results:
:FETCh:ACPower?
Retrieves the data specified by n
:MEASure:ACPower
[n]?
Switches to ACP measurement, restores default values, starts the
measurement, then retrieves the data specified by n
:READ:ACPower[n]?
Starts the measurement, then retrieves the data specified by n
Remote Command Results
The following table describes the results returned by the :FETCh, :MEASure, and
:READ queries listed above, according to the index value n.
