[time-nuts] Fw: Re: Looking for HP 10811D manual (if such exists)

It looks like it, yes.  But it's not the same.  I have a  Samsung version of the Z3805A which I'm pretty sure uses the same DOCXO as the Z3801A.  The one in the picture is smaller, and it only has one power cable coming from the case.  The HP DOCXO has two power cables plus the two signal cables.

 Bob,
That OCXO looks suspiciously like the double-oven 10811 OCXO used in the HP Z3801A GPS-based frequency standard.

Cheers,

Speaking of 10811 OCXOs, can anyone identify the OCXO in the picture, and the device it originally came from?  I'm assuming it's an HP OCXO from its similarity to the OCXO in my Z3805A.  The unit in the picture is an FO-18M, 10M OCXO FREQ STD, from BT7TBL that I bought from ebay sometime ago.  I've moved the EFC and 10Mhz connections to the back for external access.

Bob
