Unlike Rb's Tbolts do not need a heatsink. The OCXO to some degree holds the board temperature wise constant. We all know that walking past it we see a change. That is not the OCXO but the board and our tests show that the DAC which is not a DAC in the classical way has a 1 E-10 per C sensitivity. No temperature or voltage control.

Hi It gets back to the term “optimum performance” and the Time Nut bias towards eliminating any source of degradation. Even while locked, temperature does get into the DAC. Blow some air on a unit and watch things move around. It does not go unlocked. It does not exceed any of the specs on it. It does move a bit and you can see the “bump” in a phase plot. Simply blocking drafts is a good first step. Bob > On Jul 24, 2017, at 8:33 PM, paul swed <[email protected]> wrote: > > Interesting discussion.
