Re: Wrong cable... How bad is it?


It depends on what you are calibrating for. If it was a VNA I would say start over.. For a scope and a short cable you may see some odd overshoot but in typical use the scope input is 1 Meg and the cable is short so it may have no impact. Check between a 50 Ohm and a 75 Ohm cable and see if you do see a difference in what you are looking at.
