One of the few things I dont have a manual for

Can anyone tell me if there is an HP model number for the Reference
Oscillator Assembly (A19) in the 5071A? Might be a a 10544A ?

Thanks,

It was a 10811 that I modified to get more tuning range by replacing
the stock varactor with a hyperabrupt type, probably my favorite
MV209, but I can't remember for sure.

Just yesterday, I designed a phase modulator using an MV209.

The OCXO was 05071-60219. As Rick says, it was a modified 10811. The 10544 was long gone by the 5071A's time.

See the Mejia-Norton document in the ko4bb.com Manuals section for the exact specs...

Joined the club of obsolescence.
Digikey: No Stock, no price.

Just like the BF862, my favorite FET and BFG31, the last RF PNP
that could stand a little power. :-(
There were lots of them in my distribution amplifier.

Not recommended for new designs: NXP.
