Last week I got myself a #TinySA Ultra. It has a signal generator mode, so here I am today comparing its oscillator stability against the bench signal generator using a #NanoVNA reflashed as #TinyPFA.

I was having trouble believing the output of my adev script because it showed such high values, so I loaded up the data in TimeLab which drew the same exact plot. 🤷 I also plotted the measured phase delta between samples. I do *not* think that's thermal (air conditioning) related. #timenuts
