I ran my 5370B for one hour, counting its own reference with a one second gate. The summary of the results are:
min 9999999.99650 Hz max 9999999.99963 Hz avg 9999999.99796 Hz median 9999999.99787 Hz Per the manual's Performance Test 5 (page 4-12) the spec is +/- 0.005 Hz. It would be nice if my average was 10,000,000.000 HZ but?? From a Time-nuts thread of several months ago, the adjustment for this result is very touchy and it's likely you will make the result worse rather then better. Since mine is in spec, I'll leave it alone. I have sent the graphical & raw data to Corby, if anybody else is interested please advise me of your email address.

An earlier post implied that the last couple digits will wander around due to the way its designed. I'd like to know what a couple different counters show to see if that is indeed true!
