Adjacent Channel Power—Reference Channel FFT Segments
[:SENSe]:ACP:FFTSegment <integer>
[:SENSe]:ACP:FFTSegment?
Selects the number of FFT segments used in making the measurement
of the reference channel (carrier). In automatic mode the measurement
optimizes the number of FFT segments required for the shortest
measurement time. The minimum number of segments required to
make a measurement is set by your desired measurement bandwidth.
