> The ground cable (LEMO00) in aida07 was disconnected, it has been reinserted and the waveforms now look good. > > (All data below taken with thresholds 0xA for all) > > Noise in aida09 is visible and aida12 is quite high too. (All of DSSD3? Except aida10?) > Event rate in them is very high. The lower frequency noise visible in figs 5,7 seems slow enough for the ASICs > DSSD#2 has nice event rate and DSSD#1 seems "OK" > > Leakage currents high but S4 very warm at the moment as roof is still closed. > > Some PCBs from bPlas are touching the ribbon cables, so should be insulated better. > > Next S4 access later this week will reseat all connectors to ensure good connection. > Other ideas can also be done > > Figures: 1, 2 - Good Event + ADC Data Stats > Figure 3 - Rate Spectra (log scale) > Figure 4, 5 - Odd FEE64s Waveforms, 50 MS/s (Sample rate 0) and 5 MS/s (Sample rate 10) > Figure 6, 7 - Even FEE64s Waveforms, 50 MS/s (Sample rate 0) and 5 MS/s (Sample rate 10) > Figure 8 - Grafana (DSSD HV) > > aida01-aida04 DSSD 1 > aida05-aida08 DSSD 2 > aida09-aida12 DSSD 3
