EMI/EMC/SI/RF practical tips

Three real-world case studies show how RF power amplifiers and creative benchtop setups solve complex radiated immunity failures in hours instead of weeks. From military-grade testing to runaway medical motors, discover techniques that save time and money while identifying root causes traditional methods miss.

Resonances in components are a well-known topic for electronic designers when working in high frequencies (e.g. EMI/EMC). Do not forget to test your components with an impedance analyzer, especially if they are custom magnetic components.

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.

Why do cables radiate? Common mode currents are the culprit. Through four practical experiments, learn how return paths, grounding switches, and parasitic capacitances determine whether your current stays differential—or becomes a radiating common mode problem.

Parasitic oscillations are a sneaky source of EMI/EMC failures. With the right layout and simple fixes—like reducing gain or breaking feedback loops—you can eliminate emissions without costly redesigns. Learn how to spot and stop these hidden troublemakers in your circuit.
