Re: NanoVNA Noise improvements. Hugen79's NanoVNA Github Issue #14 #filtering #noise #improvement #hack #circuit

 

In addition to 10kHz chirps, I hear a prominent tone ~ 300Hz when testing phono inputs.
I suppose that is the rate at which nanoVNA steps frequencies;
it increases about 10% which switching to CW.

Is this filtered out of ADC?
