Curve Tester 💠 prova componenti a comparazione

Let us see how to test electronic components by visualising their characteristic curve by comparing a good component with one to be tested. In fact, this curve tracer has 2 channels (A and B). In addition, when channel B is not in use, it sends a low-current 5V pulse output (one pulse of short duration every second) useful for polarising the base of a transistor, for example. never apply voltage to the inputs it would be damaged immediately.
