I asked about using multi boards some days ago, and I got answer to use external trigger. (Thanks Stefan!)
And here is another question. I made two external triggers and try to acquire coincidence data using two boards. but DRS Oscilloscope program can connect only one board and don`t acquire both of them simultaneously.
So I tried to use two computer for each board separately, but, well, you already know, I failed to acquire because two computers don`t promise to synchronize the two boards acquisition.
Is there any method to solve this problem?
1. I want to acquire coincidence data from the two DRS 4 Evaluation board V4 simultaneosly.
2. I have external trigger to provide the two boards at the same time.
3. How can I get data from the two boards?
You have to write your own program. DRS Oscilloscope does not (yet) support this. Take drs_exam.cpp as a starting point and try to extend it to two boards. One tricky point is that the external trigger may only fire AFTER the two boards have been read out. So you need some means of re-enabling the external trigger after you read out both boards.
That`s very bad news for me. I don`t have much time to study & write C programming...
Anyway, Thank you very much Stefan.
