HI
i have confused myself and cant find a clear simple description for an answer. on a digital scope i have the spec sheet quotes the input impedance as 1MEG. so does this mean that it already has this impedance (so i could just connect a basic croc clip probe) or does it means it needs a min 1 meg probe.
Also if it already has a 1meg impedance and i connect a normal x1 1 meg probe does this not increae the impedance by adding the two together.
