Hello,

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.
