FFT1M option only works up to 131072 FFTs

Hi

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 adjust the DSP Memory Model (Titelbar under Extras -> Configuration): The default is set to "Medium" which limits the maximum FFT size to 131072 FFTs.

You need to set it to "Large" for a 1M FFT:

Rose the DSP Memory Model for a higher FFT rate

 

BTW: Setting it to "Small" will reduce it to 32768 FFTs,
