Subject: synchronisation of readouts of two boards for offline analysis 

 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.

The PSI46 test board has a software which allows it to accept a 16 bit number following the trigger pulse. I was wondering whether it would be possible for DRS4 board to generate such a trigger number on the trigger out line after sending the trigger. Also would it be possible to record this trigger number for every event stored by DRS4 board?

If none of this possible or requires a lot of time, then as a minimum, would it be possible to send-through only the triggers that were recorded by the DRS4 board?

Please let me know if you have better idea how to do this.

Thank you very much,

Dmitry.
