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.

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.

Near‑field probe techniques commonly used for EFT troubleshooting can also uncover radiated immunity failures. Using a real‑world audio device case study, this article shows how a simple benchtop setup exposed PCB‑level resonance, guided a low‑cost fix, and helped resolve chamber test failures.

Ever wonder why equipment mysteriously fails in the field? This case study reveals how one manufacturer solved frustrating intermittent timer resets in an industrial kitchen—using clever EMI troubleshooting techniques with an EFT generator and near-field probe. Learn their practical fix that ended costly service calls.

A 140 MHz radiated emissions failure led straight back to a 10 MHz clock — but not the way anyone expected. Near-field probing revealed the real culprit was current, not voltage, doubling the frequency where it mattered most. A practical reminder to measure both when chasing down EMI.

The new SX probe heads' high measurement resolution allows the developer to pinpoint RF...
