FFT Length (HE/EHT) (802.11n/ac/ax/be/bn)

Menu Path: MeasSetup > IEEE 802.11n/ac/ax/be/bn Demod Properties > Advanced tab

Range: 256, 512, 1024, 2048, 4096 (802.11ax/be only)

The FFT Length (HE/EHT) parameter specifies the Fast Fourier Transform length. See Preset to Standard for the preset values.

FFT Length (HE/EHT) is only visible for 802.11ax/be standard formats. For 802.11n/ac standard formats, see FFT Length.

The FFT Length is coupled with the Standard parameter on the Format tab. When a Standard is selected, the FFT Length is automatically set to the correct value. Similarly, selecting a FFT Length will change Standard to the appropriate selection. For example, an FFT Length of 4096 will set Standard to 802.11be 320 MHz.
