Electric vehicles introduce complex EMC challenges as high-switching inverters and E-drives create electromagnetic interference affecting safety-critical ADAS systems. Traditional static testing at constant speeds is insufficient—dynamic EMC testing under realistic driving conditions is essential to properly characterize emissions and ensure compliance.

Why spend $1500+ on commercial ESD targets when you can build your own for under $100? This EMC lab's clever DIY solution uses high-voltage resistors and SMD components to create an IEC 61000-4-2 compliant target that rivals expensive commercial alternatives.

Overconfidence in basic ESD testing can create dangerous blind spots. Three case studies reveal how standard floor resistance tests miss critical system failures when mobile equipment loses electrical contact, exposing sensitive electronics to static damage despite apparent compliance.

New harmonized EU cybersecurity standards EN 18031-X took effect August 2025, requiring radio equipment manufacturers to conduct risk assessments across three overlapping standards. Despite similar requirement codes, critical differences in text and restrictions can impact compliance strategies.

This article provides one EMC engineer’s perspective on the important aspects of the history of Part 15 - Low Power Devices, under the Federal Communications Commission’s rules.

As connected medical devices become more integral to patient care, ensuring their cybersecurity is critical to both patient safety and regulatory compliance. This article explores how the IEEE 2621™ standard and its associated certification program provide a structured, standards-based approach for engineers to design, validate, and secure these devices throughout their lifecycle

Since the discovery of electromagnetic interference (EMI) in the early 1900s, the need for testing for radiated emissions continues to grow as products get more complicated. The time to test has also grown, and, in some cases, can take days to complete. The introduction of fast Fourier transform (FFT) technology into EMI receivers can greatly decrease the required testing time, but is it applicable for everyone?

Watchdogs are essential system design components that reset systems for recovery. Originally standalone timer ASICs, they're now integrated into power management devices, voltage supervisors, and microcontrollers to enhance functional safety. This article explains various watchdog timers, their interactions, and design strategies for multiple watchdogs, particularly in functionally safe multicore systems requiring independence.

How can the EMI/EMC community continue to blame this accident on electromagnetic interference (EMI) from the USS Forrestal’s on-board AN-SPS-43 search radar when the official US Navy inquiry comes to different conclusions?

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 2 will examine specific aspects of switched power converters.
