Sense]:Acp:fftsegment <Integer - Agilent Technologies E4406A VSA Series Programmer's Manual

Range: 300 Hz to 20 MHz for Basic, cdmaOne, cdma2000,
W-CDMA (3GPP), W-CDMA (Trial & Arib) mode
1 kHz to 5 MHz for iDEN
Default Unit: Hz
Remarks: With measurement type set at (TPR) total power
reference, 1.40 MHz is sometimes used. Using
1.23 MHz will give a power that is very nearly identical
to the 1.40 MHz value, and using 1.23 MHz will also
yield the correct power spectral density with
measurement type set at (PSD) reference. However, a
setting of 1.40 MHz will not give the correct results
with measurement type set at PSD reference.
You must be in Basic, cdmaOne, cdma2000, W-CDMA
(3GPP), W-CDMA (Trial & Arib), iDEN mode to use
this command. Use INSTrument:SELect to set the
mode.
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.
Selecting more than the minimum number of segments will give you
more dynamic range for making the measurement, but the
measurement will take longer to execute.
To use this command you must first set SENSe:ACP:FFTS:AUTO to off.
Factory Preset
and *RST: 1
Range: 1 to 12
Remarks: You must be in Basic, cdmaOne mode to use this
command. Use INSTrument:SELect to set the mode.
