Enjoy your TimeLab. It's particularly educational to see the ADEV and 
HDEV curves flap up and down in the top tau range displayed, and then 
for shorter taus it will stabilize as more data has been gathered, and 
then as measurement continues, the curve stabilizes for mid-range taus.

That's not a bad way to go. Trimming the OCXO is a bit optional if you 
slave it to the 10 MHz, but good if you want to use it free-running at 
some later time.

As I mentioned in a separate comment, no, the PM6680B does not 
completely replace your 5370B.

We always do!
