Hello. I need to digitize pulses from two PMT. After pulse on first PMT I have to save all pulses from second PMT in range 200 ns (and starting pulse from the first, and time range between pulse from 1st PMT and pulses from 2nd PMT). Is it possible with DRS evaluation board?
If you run at 2 GSPS, you have a time window of 500 ns like on an oscilloscope. If you trigger on 1st PMT, you will get the traces of all 4 inputs for the next 500 ns. So I guess this is what you want.
Ok. And, If I understand correctly, the main bottleneck in data readout is USB. I.e., theoretically maximum readout rate is 500 Hz. Is it true?
On the evaluation board, yes. This board is not optimized for high readout rate. If you do your own electronics, like GBit Ethernet, you could be much faster.
