1. An isolated differential current shunt measurement probe, comprising: an isolation barrier; a differential input side having a low-noise, low-impedance input configured to receive a voltage signal across a current shunt connected to a device under test and transmit the voltage signal across the isolation barrier; and an output side configured to receive the voltage signal across the isolation barrier and output the voltage signal to a test and measurement instrument, wherein the isolation barrier is coupled between the differential input side and the output side, and maintains isolation between the differential input side and the output side, wherein the isolation barrier is a microwave isolation barrier.
