Subject: Trigger multiple boards independently 

Thank you Stefan. Actually I noticed that the source code of drs_exam was available after I started this thread, and that was the solution that occurred to me too. I'll give that a try.

A related question is: if the 4 boards are triggering at max rate (500Hz), would the total data throughtput (of the four boards together) be 2GHz (500Hz x 4)? Or is the limitation on the readout, rather than the triggering?

Best,

Javier.

Unfortunately an independent operation from a single computer is not supported by the software. You can try to modify the drs_exam program and extend it. You can poll all boards in sequence and just read out that one which got a trigger, then start the loop again. But I don't know how good you are in programming. I needs a bit of experience to do that.

Hello,

I recently acquired 4 DRS4 boards and I wanted to ask if it was possible to trigger them independently from the same computer.

I know that you can daisy-chain boards and trigger them all at the same time, but in my case, each of my boards record independent events, so I want them to trigger when trigger conditions are met in each board. I currently use the provided DRSOSC software, that can trigger on only the board that is being displayed at that moment. I tried opening several instances of DRSOSC to associate each to each board, but that is not possible since the second instance already does not find the boards. I wonder if there is a way of triggering from each board independently without having to use four computers.

Thank you,

Javier.
