Re: [time-nuts] OCXO info?
Hi A picture of the end with the markings on it would be a big help. It looks a lot like a late 50's / early 60's design. I would not count on it's performance being real good by todays standards.

Re: [time-nuts] OCXO info?
Hi Assuming it's an R1051 "standard" you then have to know who made it. Some of the later parts made by the replacement parts empire were of questionable performance / reliability. The side with the markings likely would tell us a lot. Simple answer - when it's not Chinese New Year, the auction sites are full of < $20 OCXO's (including shipping) that will do a *lot* better. If you are patient, you likely can get below $10. How they can do that with shipping is a total mystery.

Re: [time-nuts] OCXO info?
Yes, it is the R-1051 frequency standard, I have one. It was made by General Dynamics, and was rated, if I recall, at 1x10E-8 per day.

That was the side with the markings, such as it is. CAGE # comes back to 'Target Corporation', so aftermarket spares? And yes, it is certainly from/for an R1051. > > Simple answer - when it's not Chinese New Year, the auction sites are full > of < $20 OCXO's (including shipping) that will do a *lot* better.

Looking at the schematic, there's no native way to pull this guy. I can wait for the CNY festivities to wind down. :) Thanks Bob & Arthur! -ls- ___ 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.

Ignacio, for details check: http://www.ko4bb.com/cgi-bin/manuals.pl?dir=HP_Agilent/HP_-_105 Early 105A/B's came with the 00105-6013 OCXO, as covered by the above manual.

OK Adrian, thank you. Probably it is a good candidate to be disciplined.

Re: [time-nuts] OCXO info request
Adrian, I have found another reference, this oscillator is also used in the HP 5061a Cesium freq. standard: http://www.leapsecond.com/museum/hp5061a/5061a.pdf Best regards, Ignacio Adrian escribió: > Ignacio, > > for details check: > http://www.ko4bb.com/cgi-bin/manuals.pl?dir=HP_Agilent/HP_-_105 > Early 105A/B's came with the 00105-6013 OCXO, as covered by the above > manual. > > Adrian > > EB4APL schrieb: > >> Hi, >> Since there is plenty of experience here, I want to locate info about an >> OCXO.
