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.

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.

I have two of these units and am quite pleased with them. Other than an app note indicating that they are leap second compliant I've never seen any documentation re the Z3805.

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.
