Patented RF-free Ramsey housings from Saelig now provide improved, highly-isolated bench-top environments for performing pre-compliance and evidentiary investigations of electronic devices.

Solving EMI problems isn’t only about ensuring that a product can meet EMC regulations and standards (although it’s a significant part of the job). Another crucial reason for addressing EMI issues is to enhance product reliability, especially when a product operates in public or industrial areas where there are many different types of noise sources.

A manufacturer of electrical test equipment took an order worth several million dollars for new product to be used worldwide to help service the vehicles manufactured by a major multinational.

Conducted emission tests can provide reasonably accurate results and also serve as a reliable indicator of radiated emissions, as some of these emissions propagate through cable wiring.

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

The paper machine process requires precise control of the paper sheet tension as it progresses through the machine.

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.

Pre-compliance testing saves time and costs by detecting potential problems early in the design process. The use of appropriate tools and techniques improves the chances of passing the full compliance test on the first try.

During conducted emission tests, one of the challenges manufacturers face is the resonance peaks in the harmonic noise somewhere between 10 MHz and 30 MHz. Often, no amount of filtering will eradicate or attenuate the peak.
