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.

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.

Ken Wyatt's blog explores DIY radiated emissions testing. He breaks down the gear you'll need—think spectrum analyzers and special antennas—and shows how to set up your own test space without breaking the bank. It's all about catching EMC issues before the big, pricey lab tests.

Most engineers are familiar with near-field probes and that they are sensitive to E- or H-fields emanating from circuit boards, cables or enclosure seams. They are really the first order of business when evaluating a circuit board or system.

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...

This is the 10th and the final article in a series of articles devoted to the design, test, and EMC emissions evaluation of 1- and 2-layer PCBs that contain AC/DC and/or DC/DC converters and employ different ground techniques.
