keyword=S2m-13R ADC HV CheckLHRS S2m channel 13R (index from 0). Figure 1 shows the ADC spectrum
with HV and Figure 2 shows the ADC with HV. Clearly the pedestal is
noisy with or without HV. The RMS changes by about 6 channels, but
there is real signal under the huge pedestal. During the next access,
we should check the cable connections and if needed change patch panel
connections.
