Glitching in PEM EX channels

Matthew Ball, Dripta Bhattacharjee, Adrian Helmling-Cornell, Robert Schofield

Recent DQ shifts have noted that the H1:PEM-EX_ADC_0_17/18/19_OUT_DQ channels have started appearing in hveto (51515, 51759). Channel 17 measures the potential between the low-voltage ESD chassis and the beamtube. Channels 18 and 19 measure the voltage of the power supply for the ESD. We confirmed today that all three channels were set up properly, so it does not appear to be a wiring issue causing the glitching.
