Precision to measure frequency

 

How accurate is it to measure frequency using TinySA? It's possible to use to set reference oscillator from a ham radio rig?
?
?

?

?
 

As can be read in the spec on the wiki:?
  • Frequency accuracy equal to the selected resolution bandwidth

I'm also looking for accuracy compared to commercial equipment
 

Commercial equipment specifications are also listed online.? You can access HP/Agilent/Keysite, R&S, Tek, and others online.? All of them have specifications readily available online.

The tinySA has an internal 30MHz TCXO which is quite accurate already. Any deviations can be further corrected by using a precision clock counter and performing a calibration like Erik showed in one of his videos:

There is not an internal IF counter,? so you may use only the marker.
TinySa? it's the smallest semi-professional spectrum analyzer, I have R&S and HP on my lab also, but for a lot of purposes it's enough.
Only a few known bugs remain.
