A few basic system components are frequently used to mitigate or suppress electromagnetic interference (EMI) in devices. As engineers and technicians involved in compliance engineering, it is important to know what these components are, what they do, how they’re most effective, and when they’re ineffective.

Before diving too deep into the nitty gritty of high frequency probing techniques, it’s imperative to understand a few basics, as described in the remaining portion of this article. The basics include probe calibration and null measurements and a description of the various types of voltage probes available, including their strengths and weaknesses.

This month’s article focuses on the value of non-traditional training courses. To be clear, when referring to non-traditional training courses, what is meant is anything that is not considered a traditional program like a two- or four-year degree program, a Master’s, or Ph.D. program, etc.

Introduction IEC 61000-4-6 is titled “Electromagnetic compatibility (EMC) - Part 4-6: Testing and measurement techniques...

Even if you are not involved in the practice of the measurement of antennas but have a passing interest and would like to learn more, this is the standard to read. Doing so will quickly get you up to speed, saving you many hours of unnecessary research and much confusion.

To provide in-depth coverage of ESD testing methods, in this article, we look at another type of ESD testing based on the “Human Body Model” (HBM) method of ESD testing.

This article describes a loss-less impedance matching technique that does not require the use of discrete components but instead uses cables or printed circuit board (PCB) traces, i.e., distributed elements or transmission lines.

As a compliance engineering professional, you may encounter situations when you must consider how multiple and often conflicting requirements apply to your product and how to deal with them effectively.

There are many books and other reference materials available that describe proper printed circuit...

This article addresses two very common questions involving two interrelated and specialized sub-fields within the realm of compliance engineering.
