Hardware Design Description Introduction The PCB scope is the result of a challenge I set for myself – to build a practically usable oscilloscope with a minimum amount of components and for minimum cost. The practical benefit is of course that this is an instrument that I hope will be interesting to many teachers, students and hobbyists looking for an affordable, simple tool for their .
