Does anyone know more about it? http://www.prc68.com/I/Z3805A.html#OCXO Looks like the same as in Z3801A, that is a 10811 with additional oven wrapped around it and put in a case. Lots of details on it if you look at Z3801A sources of material. Also is the DB-25 pin out known? http://www.prc68.com/I/Z3805A.html#DB-25 Check the Z3801A manual.

It looks more like a HP serial number.

Re: [time-nuts] Z3805A OCXO p/n 3505A09422?
The OCXO is a 'double oven' 10811 and that is the serial number. I have a 'spare' and can probably find more information in my 'files' if needed. Good luck.

Does anyone know more about it? As others have said, it's a 18011, and you are looking at the serial number. IIRC, It was made in late 1995 (1960+35). The 05 is the 5th week of HP's Fiscal year that begins Nov 1 (still today), which I think puts the date of manufacture between Nov 29th and Dec 6th 1995. It's also a darned fine bit of kit :) (Sorry, I know I'm sad and bad, I just couldn't resist :)] Iain (who can probably still remember what he was doing that Nov 1 at HP!) ___ 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.

Check the output on a spectrum analyzer for 5 MHz content. I've seen several internet-sourced Z3805As that were explicitly claimed to have HP 10811-60165 oscillators, but actually contained unlabeled oscillators that look like this one and appear to be 5 MHz oscillators with doublers (the output contains 5 MHz at ~ -50 dBc). I have heard that Symmetricom may have made oscillators fitting this description, but have no further knowledge.

Yes, indeed, I've got one with a 10811 and one with a symmetricom 5 MHz oscillator with doubler. Volker Am 19.04.2013 01:15, schrieb Charles P.
