Step 22: Soldering and testing
At this stage there is not much to say because I already explained in detail all the parts of the circuit. I tested it with an oscilloscope, that a friend borrowed me, to see the signals at each point of the circuit. It seems that everything is working alright and I am pretty satisfied.
The connector for the incoming signal could seem a little strange for someone that does not come from the High Energy Physics, it is a LEMO connector. It is the standard connector for nuclear signals, at least in Europe as in the USA I have seen mostly BNC connectors.
