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.

Interference problems caught late in development can mean costly redesigns and certification delays. Don MacArthur walks through the PCB layout, grounding, and shielding strategies engineers need to tackle EMC challenges head-on—before they become showstoppers.

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.

Compliance engineering demands constant adaptation — and training is what makes it possible. This piece examines why continuous learning is essential for keeping pace with evolving standards, emerging technologies, and global regulatory requirements, and what it means for engineers who want to stay ahead.

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.

ESD flooring systems fail more often from misunderstanding than bad materials. This article walks through nine common pitfalls — from confusing anti-static with ESD-safe to poor grounding and installation shortcuts — and how to avoid each one.

Tackle radiated emissions before heading to the test lab. This practical guide covers the essential workbench toolkit — near field probes, RF current probes, and spectrum analyzers — including DIY options and affordable commercial choices for identifying noise sources and reducing cable emissions.

Learn the essentials of EMC troubleshooting for product designers with this introductory column from Kenneth Wyatt. It explains why EMC failures derail product launches, highlights core design challenges, and offers foundational resources to help engineers start diagnosing emissions and immunity issues directly on the bench.

Radiated emissions testing is a critical—and complex—step in EMC compliance. This practical guide walks engineers through preparation, equipment setup, and troubleshooting strategies to help identify and resolve emissions issues before they become costly certification failures.

Changing enclosures, PCB layouts, component sources, or software doesn't mean the schematic changed—but it may mean your EMC certification did. This installment of Standards Practice breaks down which hardware modifications trigger the need for retesting, and why skipping it can be a costly mistake.
