Three pre-compliance measurement software packages are put to the test, comparing how each one automates radiated emissions testing and shaves hours off manual measurement work. The review shares hands-on pricing, quirks, and lessons learned from running each tool in the field.

Third-party EMC chambers can cost millions to build, so what does an accurate in-house setup actually require? This first installment breaks down the analyzers, antennas, preamplifiers, and tripods needed for radiated emissions pre-compliance testing, plus real-world test locations that stand in for a proper chamber.

Saelig has rolled out the 4th generation AIM-TTi PSA Series 4 handheld spectrum analyzers, adding real time FFT capture that catches transient and frequency hopping signals conventional swept analyzers miss, built for RF engineers working in demanding field conditions.

When cables become the culprit in radiated emissions failures, an RF current probe can catch what near-field probes miss. This installment of EMC Bench Notes walks through measurement technique, transfer impedance math, and a downloadable E-field calculator for pass/fail estimation.

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.

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.

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.

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.

Spectrum analyzers are essential for EMC testing—but only when used correctly. From setup and calibration to antenna selection and data interpretation, this guide covers best practices to ensure accurate measurements and smooth compliance with regulatory standards.
