I recently got a Thunderbolt with a defective Trimble oscillator. It won't get within 60 Hz of zero-beating WWV. Tried the reset to factory defaults to no avail. I have been promised a replacement.
So I have some questions. 1. How close should the 10 mHz be on startup? 2. What are the normal ranges for DAC voltage et al.? 3. How long should it take after getting satellites until the 10 mHz is locked in? 4. How much performance difference is there between the various firmware versions? Can these be updated in the field? 5. What are the optimum loop control values for 10 mHz purity? Are they different for best 1pps jitter? -- Chuck Forsberg WA7KGX N2469R [email protected] www.omen.com Developer of Industrial ZMODEM(Tm) for Embedded Applications Omen Technology Inc "The High Reliability Software" 10255 NW Old Cornelius Pass Portland OR 97231 503-614-0430 _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
