How Equalization Works in 10x Passive Probes

caroline_teledynelecroy

We've been discussing 10x passive probes and their inner workings; our last post covered all the ways in which a 10x passive probe is apt to be a liability. They'd be basically unusable for any measurements at all but for one attribute: their...
