From 07:32 - 07:37 Fri 18oct2024 PDT we had another glitch on the EY CNS-II GPS 1PPS as read by the timing system's EY comparator. This had happened twice recently, 05:50-06:40 Mon 30sep2024 (50mins) and a pair the next day 07:14 (3mins) 07:42 (8mins) Tue 01oct2024.
attached are details of today's glitch, and a month trend showing all three.
On a related note, the EX CNS-II broke on the 8th Oct with a bad power supply (a wall wart). It might be prudent to schedule a replacement of EY's power supply next Tuesday.
It started again at 10:02. This time it is switching between -2200ns and -800ns
Follow up: EY CNS-II started glitching again around 10am Friday, it continued to do this for about an hour, then went good again. No further glitches since then over the past 23 hours.
