We are using DRS4 Rev.2.0 board.
We want to measure number of pulses generated by charge particle detector. These negative going analog pulses are very fast having rise time about 2nS.
We want keep threshold level to -20mV. We expected pulse rate to be about 100 to 200 Hz.
I need help to implement this in current DRS board with dead time free operation.
If you just want to count pulses, you do not need a DRS board. Just use a discriminator and a counter, that's much simpler. The DRS board is not dead time free.
Thanks for your prompt reply.
Along with pulse rate we also want see pulse shape as well as charge measurements. That is why we are exploring this option with our existing DRS Set-up.
