Dear Stefan,
I am trying to synchronise the readout of two test boards, one is the DRS4 test board, the other is PSI46 test board (used for the readout of CMS
pixel chip) for the offline analysis. I think that the most secure way to accomplish this is to pass a trigger number from one test board to the other. |

Dear Stefan

a mixture of pions with a small percentage of protons. Pions are close to minimum ionising and were producing the signals on the order of 250 mV (Landau |

Working with the DRS evaluation board we noticed some funny behavior: See attatchment 1. In about 1% of scope traces we see the first and last bin take
on a value substantially different from the baseline, note the small spikes on the end of the traces. These spikes occur across all channels and either
appear in all channels or in none. Attachment two shows what several thousand scope traces look like. You can clearly see that some of the traces are offset |
