Regarding the Thunderbolt, I got some information from the Trimble sales manager for timing products:
The Thunderbolt was designed and built in-house (of course from parts bought from outside sources). So, the software and IP are Trimble, not OEM'd. Any resemblance with the Symmetricom 58540A unit is pure coincidence (or more likely purposely made to look the same in order to try and capture some of the same market, since the Thunderbolt was there first). A cursory look at the HP 53540A and Thunderbolt specs, particularly for holdover, will confirm the units are not the same, not even in the same league (Thunderbolt: +/- 1uS/2 hours, HP 53540A: 100uS/1 hour, which is hard to believe) The engineers who designed it are still at Trimble and are churning current Trimble timing products.
