An Arduino-based board with no solid ground return plane makes the perfect "what not to do" test case. Near-field probe measurements, spectrum analyzer captures, and real emissions data reveal why two-layer designs can be EMC trouble — and what it takes to fix them.

Spectrum analyzers are the go-to tool for diagnosing conducted and radiated emissions — but knowing how to configure them makes all the difference. Kenneth Wyatt walks through key settings, trace strategies, and practical tips for getting reliable results on the bench.

This whitepaper demystifies the IEC 60601 family of medical electrical safety standards, explaining general, collateral, and particular requirements and how they impact global market access. It offers practical guidance on integrating compliance, risk management, and testing strategies early to streamline regulatory approval and accelerate time to market.

Via placement and trace geometry significantly affect decoupling capacitor performance. This final installment of a three-part series presents conducted emissions measurements across six PCB via topologies, revealing how distance from the power-ground plane pair and via spacing impact EMC results.

Explore the future of electromagnetic compatibility and compliance engineering. From 5G and IoT to AI-driven testing and electric vehicles, discover emerging technologies, innovations, and challenges shaping EMC standards and ensuring reliable, interference-free electronic systems.

The future of the global economy may be unclear, but there’s at least some “bright light” for those in the EMC testing business.

Wireless devices face a perfect storm of EMC challenges—high frequencies, cramped circuits, multiple antennas battling for space, and noisy urban environments. Discover how industry giants like Apple, Fitbit, and Tesla engineer their way around electromagnetic chaos through ingenious shielding, filtering, and design tricks that keep your gadgets running flawlessly.

When your circuit misbehaves with unexplained noise and jitter, you're facing electromagnetic coupling. This practical guide walks engineers through identifying whether problems stem from differential or common mode issues, near-field or far-field effects, and provides a systematic debugging workflow to isolate sources, paths, and receivers—getting your design back on track.

Understanding how shields perform in the near field requires accounting for wave impedance differences between electric and magnetic sources. This sixth installment derives shielding effectiveness formulas for near-field conditions and reveals a surprising truth: copper outperforms steel at low frequencies, but steel's superior absorption reverses this advantage above 4kHz.

By understanding the real-world applications and significance of EMI filters, engineers can design and implement effective solutions to manage electromagnetic interference across various industries, ensuring the smooth operation and compliance of electronic systems.
