I would like to do a trailing average of frequency spectra, say averaging over the last 10 collected spectra. This was possible in version 5 of PicoScope. But in version 6 I have been unable to accomplish this. When in Spectrum Mode there is an Average under Display Mode in Spectrum Options. However, this seems to average alla spectra that have been collected. In the User's Guide it says that when enabling Average "the spectrum view shows a rolling average of spectra calculated from all the waveforms in the waveform buffer". To me this sounds as if setting the waveform Buffer to e.g. 2, the Average should be over the last 2 collected spectra. But no, the averaging still looks like it's being made over all the spectra ever collected since Start. What am I missing?
