Assuming the OCXO was sold to Trimble with 0 V and my unit has at least 12 years on it (4380 days) aging is 3.29 E-11 per day. Not bad for an  OCXO.                                                                                                                                  Bert Kehren

Hi.

According to Lady Heather, My T'bolt sits with it's DAC at about 0.2VÂ Â  
I always wonder about that.

 From the above comment, is the DAC output (and VCXO input I guess) 
bipolar, as in can range +- some amount from 0V?

I've not seen any schematics for them, so in honesty haven't a clue what 
it's likely range is, good bad or indifferent.

I did email TVB direct about the possibility of sourcing another one or 
two of them, but as he said (and I guessed) he was swamped with responses.

I use mine mainly as a frequency reference, powered on 24/7

Regards to All.
