I have been looking at the subject of Allen deviation and this has been discussed numbers of time on Time-nuts. But my question is this.
If an oscillator is stable in frequency but shifts phase 90 degrees and then comes back in a short time. From my reading I don't think that will show up in a typical Allen deviation plot that runs 1000s of readings at 1 second intervals. Typical HP5370 test setup. I think this capture approach will miss the issue. How often? Correct phase .5-3 hours, shift 5-10 minutes it seems random actually and the duration varies. Am I looking at this correctly?
