The PRS-10 switches the polarity of the C-field solenoid at 5Hz to
cancel out varying external magnetic fields.
If that is not a concern for you, for instance because you use it

Hi Dana:
My PRS10 is a couple decades old and I use it in the 1PPS locking mode. But that may not have been the default. Maybe
the surplus units just need the correct jumper change.

Hi
In this case it’s not thermal. I’ve tested a ton of parts in the same
environment ( maybe
not 2,000 pounds but several hundred OCXO’s ).
The PRS-10 gives you that hump at 2 seconds no matter what you do. It’s part of
the

Hi
I have a 740 as do others on the list. The big gotcha is the OCXO in the device.
It has various quirks that limit the performance of the device. The ADEV plot
they
show for the OCXO is a “sometimes / maybe / might” sort of thing. One of the
“get to it eventually” projects here is to see if
