20200826 -------- Anders implemented his capacitors on incoming power on the simple LV card: 1mF on C3 (i.e. 1.5V regulator) and C4 (i.e. 2.5V regulator). The current drawn is now stable at 3.2A when everything on. Runs were taken with nominal settings with reading chip 0. run 34282 with all channels and 135 time samples: ch-all-chip2000-34282-ped-test.pdf (note: full ADC scale 0-1023 on x-axis). 8 runs with 2 channels at a time and 1000 time samples: ch-all-chip2000-ped-preamp0gain0shaper0decay0.5.pdf (note: ADC scale limited to 0-100 on x-axis). Time sweeps for channel 0 for different events when all channels with 135 time samples: ch0-2000--34282.pdf The base line is stable except for the small oscillation, for some events (4,5) it happens that the oscillation is gone, for these the baseline looks fine. Time sweeps for different channels and events when full time sweep: ch-2000--.pdf The base line is stable except for the small oscillation. Note: a systematic study of the oscillations was not yet done. I.e. we do not know how often the lack of oscillations happens. Looking by "hand" showed only the above mentioned events 4,5.
