Thank you

Hi Ahlo,

It certainly is possible to perform FFT in Excel, however, we don't have instructions on how to do this.

You will need to lookup how to use add-ins within Excel's help files then load the appropriate add-in (there's one which has an FFT function) and learn how to use it within Visual Basic for Applications. Its not a particularly quick or easy thing to do though.

The quick method is to use the spectrum view in PicoScope, then save the waveform as a TXT file. You can import this as a tab delimited file with the Excel import wizard.

Best Regards,
