Thank you for your answers,

Another question : Have you ever tried to split the differential signal at the output of the DRS4 chip ? For example to feed both an AD9222 and a diff. amplifier (followed by discriminators) ?

 

Yes. Just have a look at the schematics of the evaluation board. This is exactly what is done there.

Actually in the newest version we went one step further and put the comparator at the input of the DRS chip. This way it is active even during the readout of the DRS4 chip and we can use this as a counter to count the overall hit rate at the input.
