EMC Bench Notes

EMC Bench Notes: Troubleshooting with a Nearby Antenna

A simple antenna positioned right on your bench can reveal radiated emissions in real time. Learn how to separate product harmonics from ambient RF noise, track down capacitive and inductive coupling paths, and use copper tape and foil to hunt down leaky seams and apertures.

EMC Bench Notes: Interpreting Emissions Using a Near-Field Probe

Not all EMC emissions look alike — and knowing the difference can save your compliance test. Kenneth Wyatt breaks down how to use near-field probes to identify and interpret broadband versus narrowband emission profiles, so you can trace noise back to its source before it becomes a costly failure.

EMC Bench Notes: Embedded Processor Characterization and Design Review

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.

Just Starting Out In EMC?

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.
EMC Bench Notes

Troubleshooting EFT, Part 1

Electrically fast transient (EFT/B) testing simulates switching and motor-induced transients that can disrupt electronic systems. This article explains the fundamentals of EFT immunity, outlines practical benchtop testing alternatives, and provides step-by-step guidance for identifying and resolving EFT susceptibility before formal compliance testing.
EMC Bench Notes

Harmonic Comb Generators

Harmonic comb generators are essential EMC lab tools that produce harmonically-related signals for chamber verification and troubleshooting. Learn why every test lab needs one, how to build a simple DIY version for under $50, and discover the best commercial options with unique features. From measuring cable resonances to portable chamber validation, these versatile devices belong in every EMC engineer's toolkit.

Case Study: Point of Sale Terminal ESD

Field failures traced to ESD-induced USB hub damage in deployed POS terminals. Through systematic H-field probe analysis, we identified poor connector-to-chassis bonding as the root cause—a preventable design oversight with expensive retrofit implications.
EMC Bench Notes

Understanding and Dealing with ESD

ESD failures are increasing as products shrink and use lower voltages with smaller noise margins. Learn how to trace ESD current paths using H-field probes and oscilloscopes to quickly identify where discharge energy flows, enabling targeted fixes like bonding and shielding to solve immunity problems efficiently.
