Hi there,
I've noticed a couple of Trimble OCXOs listed on "that auction site".
Specifically, model numbers:
- 65256
- 49423
- 34310 C1
They all seem to be 12V, 10MHz, sine-wave units. Does anyone know if
there are any other differences between them? Do any specific ones
perform better than the others?
There's a bit of a price difference between them, but data on Trimble
OCXOs seems to be quite sparse (a bit like data on their GPS modules,
really).
Thanks,
I bought a replacement OCXO for a Thunderbolt whose OCXO had died.
The pinouts are different.
The housing is much taller and won't fit in the Thunderbolt enclosure.
The polarity of the VCO pin is different.
That said, I was able to get the kluge to work by changing the polarity
of the loop gain.
