In replying to Didier's question.
The SR620's reference is my in-house standard. In fact a Russian high
performance rubidium that has been drifting < 5E-13/month for the past five
years. It's now ten years old and I will very much miss it when it finally
dies as it is very stable.
The results have already been corrected, for the references inaccuracy.
But I must repeat my noise floor is 2E-11/sec. This is the best the SR620
can do (actually about 1E-11 but I double it to be safe).
Best Regards
Martyn
