Using Reciprocity Theorem to Troubleshoot Immunity Issues

When traditional EMC troubleshooting tools fall short, the reciprocity theorem can reveal hidden immunity problems. This real‑world case study shows how unexpected RF sources—like walkie‑talkies—can expose susceptibility paths, helping engineers diagnose failures and strengthen designs with simple, effective fixes.

Hidden Start-up Events

Start‑up transients can hide major EMI and reliability problems. By capturing inrush current spikes and high‑frequency events with high‑bandwidth scopes and probes, engineers can uncover failures, resets, and random behavior caused by fast di/dt during power‑up—and design effective fixes.
