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 µΩ impedance measurement with the 2-port probe.

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. 

When you make a 2-port shunt through measurement using a commercial vector network analyzer the measurement includes an undesirable ground loop. Left uncorrected, the ground loop introduces significant errors. This paper shows how to solve this problem.
