| 1 | -2.2 | 1.6 | 2 | 0.44 | -2.2 | 1.6 | 2 | 0.47 | 50 | 45 | Pside perfect, problem with the digital output on Nside : the most significant bit is oscillating | Pside OK | Nside OK | ||
| 2 | -2.2 | 1.6 | 2 | 0.49 | -2.2 | 1.66 | 2 | 0.48 | 30 | 800 | modules ok (Pside and Nside), leakage current to high, HV coupling capacitors need to be changed | 4P weird data | ok | High voltage trip | |

| 8 | -2.2 | 0 | 2 | 0.02 | -2.2 | 1.59 | 2 | 0.44 | 40 | 135 | Pside ok at the begining, then datas are degrading. High current on the +2V : probably it comes from the output currrent of the ALICE128 output buffer. After waiting for a while, it is ok again and starts to degrade again | OK, 8P noisy | Noisy with pedestal variation | ||
