Hello Michael and Tom, thanks for the quick reaction!Of course I did already think that the rubidium cell doesn't work any more, but then I was astonished after more than 1 hour running how precise the output frequency is and I could not see a drift beyond the natural noise/ fluctuations which I can see as well with Tr. Thundelbolt. I did not yet look deeper e.g. observing the longtime behaviour nor did I open the box (yet), anyway I don't know much about the electronic internals. I have running the RbMon and looked to the data list which I have annexed. It doesn't explain much for me therefore I am asking for help and support to find possible solutions, there are so much excellent experts out here. I am worried that in fact the Rb capsule went over the Jordan ... perhaps it can be revitalized but I have no experience with it.I doupt a bit the lamp heater control value etc., ad5 to ad9. What is the range ... ? How shall one understand these and other values? But finally, how can one improve the situation?I am open for all good hints, instructions and ideas! (I am sure that there are other timenuts also interested ;-) )many thanks in advance Arnold Am 28.02.2018 um 21:02 schrieb Michael Wouters:Hello Arnold,A frequency offset of a part in 10E-11 still sounds healthy to me. I wonderwhether there is some kind of electronic problem? I have run 40 or so PRs10s and the lamp is the usual bit that dies.If you hook up a computer to the RS232 port, there are lots of diagnosticsavailable.

I have this item bought quite some years ago and I have manufactured an interface cable with the special connector last year. Did work fine. Taken out of storage I do get anymore the lock and PPS signal out. The 10 MHz output does look very good, the unloaded sine voltage is 2.8 Vpp and the frequency is very precise and stable very close to the trimble thunderbolt GPS-out signal at abt. 10E-11. In the annex you can see the data output with more delailed info. Can somebody tell me more, is the life at the end and what and how can be done to revitalize this nice time machine? How much time more is expectable? kind regards, Arnold _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there._______________________________________________ time-nuts mailing list -- time-nuts@febo.comTo unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nutsand follow the instructions there._______________________________________________ time-nuts mailing list -- time-nuts@febo.comTo unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nutsand follow the instructions there.
