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
