Thank you. LH does so much but finding the right command is a challenge.
I did finally find a copy of tboltmon.exe. That and LH both report that
1pps is turned
Brian,
LH can do this. Issue the command "p" to bring up the PPS control menu.

After quite some time I dragged out my Tbolt and fired it up. Comes up
OK. Lady Heather is happy. 10MHz is spot on (after an hour or so).
Problem is, 1pps is missing. 1pps is enabled (or appears to be).
Suggestions?
I am running Trimble Visual Timing Studio 2.03.12. It seems to know

Mostly because it doesn't do as much as you think it does.

Hi Bruce,
All those numbers is typical of 1310 nm laser, as there is a dispersion
zero in the 1310 nm window, but the downside is significant damping. In
the 1550 nm window you have lower damping, so you can run a factor of 10
times longer roughly with the same power. 1310 is only used for short-h
PSOF fiber has a much lower tempco:

Except for some low tempco single mode fibers the delay tempco is on the order
of 10ppm/K:
