Hi,
Tried again, the menu Fungus showed I already knew, it makes no differece between frequency or amplitude order.
But there´s the excursion button...Excursion, what´s this ?
Manual do not describe it in a manner I could understand it.
But google do:
Press Excursion to specify the amplitude above the FFT waveform's noise floor necessary to be recognized as a peak.
Aha...
Now you don't know where the noise carpet starts for the excursion, at the bottom, in the middle, rather at the top....
It is also very "thick", so the only thing that helps is to try it out.
With 35dB I "caught" at least 3 peaks, better than nothing.
But an averaging function for the FFT would be really desirable.
