Hello,

I would like to know how to set a maximum frequency to export the result of an FFT to Excel.

I explain, i have created a math function to calculate FFT of my signal, usually my acquisition rate is 4000Hz, however in some case i only need to analyse the fft Spectrum up to 100Hz, but with a good acurracy in that range. In order to reduce the export time, i would like to only export the fft analysis up to 100Hz and not 2000Hz, is it possible to do that ?

Thank

Hi,

your FFT should already be at a much lower rate depending on your block size and overlap settings. Still, you can always select a custom export rate when exporting your data. In the attached screenshot, simply type a value in the "Export rate" column to replace the default rate.
