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.
Having determined the amount of CMRR needed for 2-port measurement in the previous installment of this blog, Steve Sandler and Benjamin Dannan return with a demonstration of how to create a DUT and make a 40 µohm impedance measurement with the 2-port probe.
