[time-nuts] GPSTM NTGS50AA Problems

[Bob Camp]

Hi

Most of the Trimble stuff seems to have a "oscillator alarm" that triggers
on high drift or on EFC voltage near the limit. Your OCXO does sound like
it's not working well.

Hi to all,

 

I buy one of this to Fluke.l on ebay and I have problems I think with
Trimble oscillator (only works with DAC at 7.2V ) since I think the
reference voltage is not correct.

After a 48 hours survey with lady heather it returns OSC BAD and with
thunderbolt monitor oxco voltage error.

If I use higher tension it sims to work but no phase lock appear.

I try everything including asking help to the seller.

I think it is the the problem is on the OCXO.

Any one to help.
