FFT block size

We want to use FFT-Analysis with out Sirius-HS Systems. With 1MHz Samplingrate and the max. selectable Blocksize 64k the FFT-Frequency resulution ist only 7,6Hz. Not enough for out test enviroment. Could you implement Blocksizes of 131k, 262k and 524k to get a better FFT-resolution?

Hello Stefan,
It's possible to define FFT math channel that have this option. Go under Math > Spectral analysis > FFT and define needed resolution.
Best regards

Hello Marjan, thanks for reply.
Yes, the FFT math setup works. But mainly we use FFT for a quick check (eg. 50Hz noise check) in a active measurement. It would be fine to do this without leaving measurement. Is there a chance to select larger Blocksizes in the measurment FFT Window?
