radiated emissions

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.

Discover pre-compliance testing for automotive and military EMC standards. Learn key differences from commercial testing, setup techniques, and tips for dealing with ambient signals. Save thousands in wasted compliance testing.

Ken Wyatt provides an overview of radiated emissions pre-compliance testing. He covers equipment setup, field strength calculations, and strategies for managing ambient interference. The guide aims to enhance EMC troubleshooting skills and reduce formal testing expenses.

This series of articles delves into the design principles of power filters for switched-mode power converters and similar applications, focusing on conducted and radiated emissions. Part 1 provides an overview of filter design principles, emphasizing the need for specialized approaches to meet EMC specifications in an increasingly electrified and sustainable world.

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.

Ken Wyatt explores a more advanced troubleshooting tool for assessing radiated emission issues, the RF current probe. These are most useful for measuring RF common mode harmonic currents on cables.

There are many properties of antennas used to describe their performance. The antenna factor is most useful to those performing electric field radiated emissions measurements.

This is the fourth and final article in our series commemorating 70 years since the advent of modern EMC testing.

This article is the third in a series commemorating 70 years since the advent of modern EMI testing. But this last article is itself divided into multiple parts, due to the topic’s complexity. Unlike the previous two articles, which mainly tracked evolution and explained issues, this series of installments argues that we started off correctly seventy years ago, but then took the wrong fork in the road in 1967.
