The Challenge of Measuring a 40 u? (2000 Amp) PDN with a 2-Port Probe: How Much CMRR is Needed? | Signal Integrity Journal

In this blog, Steve Sandler and Benjamin Dannan demonstrate how to determine how much CMRR is needed when introducing a ground loop isolator to correct the error in a 2-port measurement.
