Just send Wenzel an email and ask them.  Yes, the part # indicates it's a "custom", but they probably can tell you what performance it has.  Not all the pins might be connected (e.g. Wenzel uses a standard package for these things).

James, they might answer you with your email address, but when I
e-mailed them, several times, to ask the price of one of the OCXOs they
advertised as being in stock, I never got an answer...  I suspect they
have anti individual time nut spam filters :^(

What I did when faced with one of their custom 10 MHz ovens, was to find
the stock model that it most resembled, and then a bit of Ohmmeter
measuring confirmed that it indeed had the same pin out.  This may not
be possible if it is an older one of course.

Good luck!

More likely, since they're not a huge company, they get busy and forget.  Calling them on the phone is also a possibility.  Yes, they're in Texas, which is kind of like making a foreign phone call, but they're in Austin, and Austin is different. (At least so my Texan cousins tell me).

I have some drive time so I might give Wenzel a call and see how it goes.

Meanwhile I looked around some more and found some with PTI oscillators. The pins are laid out in a square where as the Wenzel unit is in a straight row. The attached cable is the same with the same colors so I'm going to guess I can find the power and control leads. I'll make a test set up and start playing.

Got a few questions.

When it says 12 volts, most times 13.8~ 14 should be fine? These are labeled 12 volts.
Will that 12 volts need to be regulated?

Do the specs look?decent?

Here is a link to the PTI unit.?

Depends on what sort of internal regulation there is in the box. There's almost certainly some, but, on the other hand, you're looking for high performance, and there's inevitably going to be some effect from changes in the supply (noise, etc.)

If labeled 12V, that means 12V, not 12V automobile.
