Spectrum—Window Length
[:SENSe]:SPECtrum:FFT:WINDow:LENGth <integer>
[:SENSe]:SPECtrum:FFT:WINDow:LENGth?
Set the FFT window length. This value is only used if length control is
set to manual. This is an advanced control that normally does not need
to be changed.
Factory Preset
and *RST: 706
5648, for iDEN mode
Range: 8 to 1,048,576
Remarks: To use this command, the appropriate mode should be
selected with INSTrument:SELect.
History: Short form changed from LENgth to LENGth, A.03.00

|KB110|UNIForm
[:SENSe]:SPECtrum:FFT:WINDow[:TYPE]?
Select the FFT window type.
BH4Tap - Blackman Harris with 4 taps
Blackman - Blackman
Flat Top - flat top, the default (for high amplitude accuracy)
Gaussian - Gaussian with alpha of 3.5
Hamming - Hamming
Hanning - Hanning
KB70, 90, and 110 - Kaiser Bessel with sidelobes at −70, −90, or −110
dBc
Uniform - no window is used. (This is the unity response.)
Factory Preset
and *RST: Flat top
Remarks: This selection affects the acquisition point quantity and
the FFT size, based on the resolution bandwidth
selected.
To use this command, the appropriate mode should be
selected with INSTrument:SELect.
