I'm trying to learn more about the HP Z3805A GPSDO.

It has an OCXO that I haven't seen before with a paper sticker with
it's p/n: 3505A09422
The "A" normally means made in America.
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.
Best regards,
Charles
