Hi Time Keepers
Not quite an answer to the below question , but my own request for TCXO pinout info
on my recent purchase on Ebay.
The TCXO unit was designated to go into a HP5340A unit but the circuit doesn't seem to match with my oscillator module.
The unit either gets warm or oscillates but NOT both together at the same time.
Can't get a 10 MHz signal out but know it's oscillating by listening to it
with a receiver.
Perhaps it's needs surgery as per recent discussions in this forum.
Or even may need special dual power supply , again as per recent forum discussions here.
The module was made by Bulova and has p/n of 0960-0153.
It has a 15 way edge connector and a HP P/N of 05340-60036 on the module "mother"
Other info on the module states it needs +10 and +5vdc
Hope some of you blokes can assist.
Cheers from down under.

Well after re-researcing the pinouts again I decided to post this while
they are fresh.
These Pinouts are for units removed from FTS Cesium standards and were
verified by measurement in the standard.
