[Test-Equipment] HP 10544A & HP 10811A info needed

[Mark J. Giubardo]

Wonder if anyone in this group might have a schematic and spec sheet for
both the HP 10544A & 10811A Oven Oscillators.
My counter (an HP 5335A) calls for a 10811A as an option and I have in my
possession a 10544A.
>From what I have been able to find on the web, they appear very similar.

I would appreciate any info that may help me in this task. Maybe one of you
have done this already?

Thanks,
