Re: [time-nuts] Mc Coy OCXO in HP equipment.

Here are some details on how the McCoy OSC92-13B is used in the HP 70310A
Precision Frequency Reference, and how the OCXO is driven:

I am just speculating that this oscillator was used
instead of the 10811 because the 10811 would not fit.
Therefore, it would NOT be used in other equipment.
I would guess the specs would be similar to the 10811.
The 70,000 series had some general purpose power bus
that the McCoy would have to run off of.  It might
use different voltages than the 10811.
