All of the glitches are on the H2 & V2 sensor, which I believe have their own rack, corner 1 & 3 are on the other rack. I've asked Ryan to go and power cycle the CPS electronics are the rack in the CER. We'll see if that fixes the issue.

I called Jim who advised I go to the CER and power cycle the HAM3 ISI interace chassic CPS power as we were seeing the glitches in H2 and V2, I did this which has fixed the issue (for now at least).
