Trigger on one signal, look at the other, wait a while to see if it drifts. It's probably easier to notice changes (drift) if you look at both signals and align them so you don't have to use delayed sweep. I'm not sure how stable delayed sweeps are, but it should be easy to test. Just look at the triggering signal and delay out a half cycle and see if that's stable. Handwave... If I can see a 1 nanosecond drift, that's 1E-9 per second. (Old scopes aren't that good, but I said I was handwaving.) So I have to wait 1000 seconds (17 minutes) to get 1E-12. In this context, how stable is a GPSDO? If I used a Cesium for the sync input, how much fuzz would I see on a GPSDO output if I watched it wander back and forth for a day? -- These are my opinions, not necessarily my employer's.
