Dear Alberto, LF group,
Adding an amplitude measurement capability to Argo/Spectran
sounds like an excellent idea - it would enable a meaningful
measurement of relative signal strengths to be made.
DL4YHF's Spectrum Lab has such a facility - I don't know how
Wolf has implemented this, but the amplitude scale seems to be
fixed relative to the input full scale or minumum resolution. I think
this is as good a method as any - there are many different ways
one might want to specify the amplitude or SNR.
I don't understand why the measured level will vary with the total
input - surely provided the A/D converter is not overloaded, the
signal component being displayed should only be proportional to
the amplitude of that component of the input signal?
Cheers, Jim Moritz
