Conducted RF emissions are electromagnetic disturbances (noise voltages and currents) caused by the electrical and electronic activity in an item of equipment, and conducted out of that equipment along its interconnecting cables, such as power, signal or data cables.

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.

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.

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.

Discover the key sources of uncertainty in radiated emissions testing and learn how to calculate measurement uncertainty budgets. Essential insights for EMC professionals seeking more accurate and reliable test results.

This month's EMC Bench Notes reviews three affordable pre-compliance measurement software options that can simplify and automate the process of conducting in-house radiated emissions testing, saving time and costs compared to manual methods.

This article evaluates the impact of decoupling capacitors and trace length on radiated emissions.

Developing electric vehicle components or drone systems? Learn how to set up an affordable benchtop conducted emission test during R&D. This pre-compliance approach helps engineers catch design issues early, avoid costly fixes, and gain insights into radiated emissions—all before formal testing begins.

In the 21st century, we rely more and more on earth-orbiting satellites to support...
