[time-nuts] Trimble/Nortel 45000 GPS Locked Reference Oscillatorboard

[quartz55]

That Nortel board you have there looks exactly like the board I got in my Nortel NTBW50AA GPSTM.  You can find the book on-line, look for "Dual Voltage Global Positioning System Timing Module (GPSTM) OEM General Specification".  Yes the power supply is speced from 24 to 48VDC plus or minus.  They don't specify AC, but since the bridge is there it will work. 2.08A warm up and .6A at 36VDC steady state.

I'd like to see some of your LH traces if you don't mind, especially the osc trace. I don't seem to be able to get my osc trace less than ~400 ppt/div. You can see pics of my unit and traces from LH here http://s251.photobucket.com/user/DogTi/library/time?sort=3&page=1
