Default Re: Homebrew GPSDO

Today’s tests have put me into a loop.....comparing my GPSDO against another one that’s been running on my bench for a week, they are not the same frequency!

Comparing the two outputs on my ‘scope and triggering off one of them, the other trace drifts ever so slowly. A lissajous image presents a wobbling oval :-(

Now I have to find another 10MHz reference to find out which of the two is adrift!
