Hi All,
This is my first 5370B so I knew nothing about its expected behaviour. I bought it on eBay as the song goes and when it arrived I could see damage to the top right corner of the front frame that the operator panel screws into. It looked like it had been dropped and dropped quite hard. Although I could not detect any drift on the oscillator, I thought I'd try some of the 10811's I have collected. While I was about it I replaced the front frame. Interestingly enough, when the oscillator was replaced, the frequency stopped jittering around and sits quite happily at 11 digits resolution. Now, although it seems deceptively simple, I can't decide whether to tune the multiplier or not. I'd hate to be fixing something that wasn't broken in the first place. Here is an interesting page on leapsecond depicting a drifting HP 10811. http://www.leapsecond.com/pages/10811-slow/ Many thanks, Mark _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
