Hi everyone! We have designed a program to automatize IV curves(diodes) with a mux from arduino, we are programming with pyfirmata from python. All works fine but at great voltajes or currents, the curves actue strange, We have make the same test at hand, changing channel for channel and all works prefectly but with the mux, We have a strange problem. Im thinking this should be for a Breakdown voltajes from the mux maybe?
As you can see in the image, a strange curve is seen from a certain voltage.
Sorry for my english and best regards!
Fernando.
