FFT1M option only works up to 131072 FFTs
Quote from David3542 on 10/08/2021, 06:38Hi
I have FFT1M feature in my license manager, but in IQ Power Spectrum section I can't increase FFT size more than 131072
same as attached photo !
What's the reason ?

You need to set it to "Large" for a 1M FFT:
BTW: Setting it to "Small" will reduce it to 32768 FFTs,

You nee to set it to "Large" for a 1M FFT:
![]()
BTW: Setting it to "Small" will reduce it to 32768 FFTs,
Thanks you ! ,now it works fine
