A Brief History of Electrostatic Discharge (ESD) Testing of Electronic Products

This updated version of an article originally published in the March 2014 issue provides details on recent and current developments in the ESD testing of electronic products.

Automotive High-Speed Interfaces: Future Challenges for System-Level HV ESD Protection and First-Time-Right Design

This paper describes future design challenges of discrete system-level ESD protection (high-voltage, low-capacitance) of automotive high-speed data links such as multi-gigabit ETHERNET and SERDES/video-links. A special focus is put on an in-depth analysis and accurate modeling of the complex ESD behavior of the Common Mode Choke (CMC).

(Re)Discovering the Lost Science of Near-Field Measurements, Part 3

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.

Journey to the Center of the Dipole

The electrical engineering sub-discipline of electromagnetic compatibility has been described as the study of second-order effects that were ignored in college. Investigating electromagnetic fields next to a dipole is one such topic. Don’t cite Hertz and his dipole – he didn’t go there.

Return-Current Distribution in a PCB Microstrip Line Configuration, Part 2

This is the second article of a two-article series devoted to the return current distribution in a PCB microstrip line configuration.

Can Electrostatic Discharge Design Problems Be Solved with Electronic Design Automation Tools Alone? Part 2

In Part 1 of the article, we reviewed what EDA tools are good for. Here we will discuss EDA tool limitations.

No Spectrum Analyzer? No Problem – Use Python’s SciPy Module Instead

In this article, we describe a method for analyzing data using the FFT algorithm found in Python’s SciPy module. The reader should know that the SciPy module also includes methods for other FFT algorithms, such as the Inverse FFT and Discrete Sine and Cosine methods.

Questions to Ask When Purchasing Fiberoptic Links and Camera Systems Used for EMC Testing

EMI-shielded fiber optic links and cameras are revolutionizing EMC testing by ensuring accurate data transfer, real-time monitoring, and reliable analysis in the presence of electromagnetic interference.
