[time-nuts] HP10544a Technical Info needed

[Howard W. Ashcraft]

I am constructing a GPS disciplined OCXO using an HP10544a.  If someone
has a copy of the HP manual/technical data for this oscillator, I would
appreciate getting a scan.  I have already received, from a request on
the HP equipment listserv, a copy of an HP10544 schematic.

Also, while performing tests on the unit, I detected fairly strong noise
signals leaking onto my test board.  It appears to be coming from pins
5/6 of the HP10544a, which are the EFC control pin and its related
ground.  A spectrum analyzer shows the noise at about -30dbm and peaking
around 1.8 mhz.  Has anyone seen anything similar with this OCXO?
Everything else looks normal.

Regards,

HOWARD W. ASHCRAFT, Jr.
