Hi Magnus,

I knew I was missing something!  I'll warm up the Rb and test against that again.

Thanks!


Bob

Well, in that case you do measure a form of noise-floor rather than 
measuring the OCXO performance, as OCXO performance is being corrected 
out in the PPS position (and sawtooth-correction).

If you want to measure that OCXO performance, you need to do that 
against an independent PPS.

Cheers,
Magnus
