Mastering EMI Troubleshooting with Oscilloscopes

Presented by Prof. Dr. Arturo Mediano, University of Zaragoza

Debugging electromagnetic interference (EMI) in electronic circuits can be tricky, especially when failures are intermittent. In this session and, using a small power electronics prototype, we’ll demonstrate how to measure conducted emissions with a Line Impedance Stabilization Network (LISN) and advanced oscilloscopes (R&S MXO family) in both time and frequency domains. You’ll learn how to identify differential and common-mode emissions, and how to leverage voltage, current, and near-field probes to pinpoint and understand EMI sources and coupling effects. Whether you’re a practicing engineer or a student in power electronics, this session will give you hands-on strategies to tackle real-world EMC challenges.
