[:SENSe]:SPECtrum:FFT:WINDow[:TYPE]?

Select the FFT window type.

BH4Tap - Blackman Harris with 4 taps

BLACkman - Blackman

FLATtop - 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.)

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.
