Paul, I assume that "Tbolt" refers to the older 8-channel Thunderbolt with the Trimble OCXO. I have two of that model, plus I have a new 12-channel Thunderbolt E that is equipped with a "Double OCXO" and is noticeably more stable than the earlier models. While the earlier models might show 10 MHz offset peaks of as much as 80 ns, the Thunderbolt E consistently shows no more than 2 or 3 ns offsets.

I am a bit surprised that when I use it to measure the Tbolt and then the HP 3801. The 3801 comes out always better by a decade actually. Granted what I am seeing is way down below a e-12th and in fact what I am reading seems nuts to me. But can a 3801 run that much better then the Tbolt? I kind of thought they would both be in the same region.
