Martyn,
I have used a PM6681 with HP105B reference to look at:
1. FS700 (OXCO option) as a "typical" modest quality OXCO
2. An FRS-C Rb as a "low cost" Rb device
Both measured devices were either undisciplined or awaiting
the next application of new EFC; thus I limited the observation
times to 2
Pete,
That's my point.
Tom has plotted Allan Variance. I have plotted frequency accuracy.
I get similar Allan Variance results to Tom. But if I just measure the
accuracy, e.g peak to peak frequency variations, rubidium's out- perform
OXCO's even when both are disciplined to GPS.
I hope I'm no
