Step 22: Soldering and testing
I am unable to show you all the soldering procedure of the circuit because it underwent a lot of trial and error work. In the end it got a little messy but not too bad, though I will not show the underside because that is really messy.
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.
