Interference Technology

CONTENTS Introduction Basics e-Motors Battery Testing Summary Note: This article is an abridged version of the white paper “EMC and eMobility” published in 2024 by MVG, available at www.mvg-world.com. The full paper provides expanded technical detail and includes additional coverage of EV charging, which is only briefly referenced here for succinctness.

When Two TDRs Don’t Agree As modern high-speed designs push into multi-gigabit and higher data rates, EMI and EMC engineers rely on multiple signal integrity (SI) metrics to evaluate interconnect performance. Among these, time-domain reflectometry (TDR) remains one of the most direct methods for identifying controlled impedance and discontinuities. Because impedance mismatch can potentially be a source of EMI, it is important to know the impedance profile throughout the signal path.

New compact, high-accuracy instrument extends WT series coverage into high-voltage xEV and renewable energy applications Yokogawa Test & Measurement Corporation today announces the release of the WT1500 high-precision power analyzer. A new addition to the WT series, the WT1500 addresses a growing need for high-voltage, multi-functional measurement within the renewable energy and electrified vehicle (xEV) markets.

A few weeks ago, I was pulling my bins in from the curb after garbage pick-up day, and I heard a faint whirring coming from somewhere in my neighborhood. At first, I thought it was the Pennsylvania Turnpike, but the tone was different than usual. My son told me to look up.

Introduction Missile platforms operate in some of the most extreme electromagnetic (EM) environments encountered by aerospace systems. The combination of high‑power radar, directed‑energy weapons, lightning, electromagnetic pulse (EMP), and electro‑static discharge (ESD) creates a complex threat landscape that can compromise functionality, safety, and survivability.

The long-awaited revision to MIL-STD-461H was released on April 17, 2026. This revision formally supersedes MIL-STD-461G, issued on December 11, 2015. However, anyone involved in the MIL-STD-461 compliance arena understands that adoption through the procurement cycle will take time. There is no reason to discard those copies of revisions A through G anytime soon.

Read Part 1 of this CubeSats series here In 2016 and 2018, Bob Vermillion gave a series of groundbreaking presentations on “CubeSats Require ESD Handling Protocols for Launch & Space Survivability” to enthusiastic audiences of university graduate students, aerospace engineers, NASA civil servants and academic researchers at the NASA-Auburn Academy of Aerospace Quality Workshop, Huntsville, Alabama and NASA Quality Leadership Forum, Cape Canaveral.

Introduction Patch antenna printed circuit boards (PCBs) are among the most common pieces of radio frequency (RF) hardware that exist in modern systems today. Wireless communications, automotive radar, and aerospace/defense systems rely heavily on these structures for transmitting and receiving electromagnetic energy. Since these structures are produced at scale, it’s critical for RF/Microwave Engineers to understand how to characterize and test them accurately and efficiently.

Introduction The number of connected devices keeps growing every year. Millions of devices exchange data wirelessly to make our lives easier. Wireless connectivity simplifies installation by removing cables, but it uses the electromagnetic spectrum, which is becoming more and more crowded. User demands have shifted connectivity from being a convenience or a cost-reducing feature to a must-have one. Users do not want to replace the functionality of a smartphone with a wired connection.
