I have two BaF2 detectors with PMT connected to Ch1 and Ch2. At this time Im using external triger module to start DRS4. My evalution board is version 3 so I have no possibility to trigger on two or more pulses occurence on different channels. But I have this idea, trigger with analog trigger on channel 1 (start detector) will start measurement on all channels. After that using FPGA inside EVM to look if some value in Ch2 is bigger as treshold value for example 0,5V and if yes then send data by USB to PC, if signal in Ch2 is lower then restart measurement and wait on triger in Ch1. This way I want to eliminate false data transfer throw USB. Is this possible to implement it into DRS4 evaluation board firmware ?
Thanks. |
