J. Kissel for S. Ballmer Stefan noticed that the H1 SUS ETMY UIM (L1) UR and LL Coil Driver Current Monitors (specifically the FAST_IMON) H1:SUS-ETMY_L1_FASTIMON_LL_MON H1:SUS-ETMY_L1_FASTIMON_UR_MON are unresponsive to a DC offset. We should fix this.
For info : the only test that have been carried out yet (with Phil) to understand those non responsive channels was to measure the voltage between the monitor output and the anti aliasing chassis. For the 4 channels we saw a similar voltage readback increase when sending thousands counts, meaning the problem could come from anywhere from anti alias to model wiring. More details on the pb : here
