Adjacent Channel Power Ratio (ACP) Measurement

This measures the total rms power in the specified channel and in 5
offset channels. You must be in Basic, cdmaOne, cdma2000, W-CDMA,
iDEN, NADC or PDC mode to use these commands. Use
INSTrument:SELect to set the mode.
The general functionality of CONFigure, FETCh, MEASure, and READ
are described at the beginning of this section. See the SENSe:ACP
commands for more measurement related commands.
:CONFigure:ACP
:FETCh:ACP[n]?
:READ:ACP[n]?
:MEASure:ACP[n]?
For Basic mode, a channel frequency and power level can be defined in
the command statement to override the default standard setting. A
comma must precede the power value as a place holder for the
frequency, when no frequency is sent.

Returns unprocessed I/Q trace data, as a series of
comma-separated trace points, in volts. The I values are listed
first in each pair, using the 0 through even-indexed values. The
Q values are the odd-indexed values.
Returns 22 comma-separated scalar results, in the following
order:
Center freq – absolute power (dBm)
Center freq – absolute power (W)
Negative offset freq(1) – relative power (dB)
Negative offset freq(1) – absolute power (dBm)
Positive offset freq(1) – relative power (dB)
Positive offset freq(1) – absolute power (dBm)
. . .
Positive offset freq(5) – relative power (dB)
Positive offset freq(5) – absolute power (dBm)
