One more comment on the Vectron OCXO. My Tbolt shows a tuning voltage of +0.4
Volt and has 3.6 Hz per Volt. 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.

Hi.
According to Lady Heather, My T'bolt sits with it's DAC at about 0.2V
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.
