Power integrity and regulatory compliance are the technical foundation of any mission-critical system. When they fail, the consequences can risk safety and costly assets, which is why design must produce predictable electrical behavior and a clear, testable path to certification. This brings focus to a key question for program managers: what is the … [Read more...]
Understanding Common-Mode Current Paths in Conducted Emissions
Conducted emissions failures, across commercial, industrial, automotive, and defense sectors, remain consistently ranked among the top three most common EMC test failures. This is somewhat surprising, given that filtering techniques are well understood and widely used by design engineers. Yet, many products continue to struggle during conducted emissions … [Read more...]
5 Common PCB Design Mistakes for IoT Devices
IoT products are often seen as an entry-level product for many PCB designers, and they require application and protocol development. It’s no wonder so many engineers and design firms market themselves as IoT solutions providers. Developing an embedded application and throwing it on a microcontroller is all well and good, but you’ll never deploy thousands or … [Read more...]
Building an IoT Device: Should I Be Concerned About EMC? Discovering the RED
Every day, more and more objects are getting connected, building local networks and connecting to the Internet. While the development of new connected devices has never been as accessible as it is today, there are still many questions around how to legally bring Internet of Things (IoT) devices to the market. This article aims to clarify the process of … [Read more...]
An Overview of Coax Limiters for use in HF Systems
OVERVIEW Critical communication and instrumentation lines subjected to very high energy RF pulses require RF limiters with exceptionally high pulse power capability. A discussion of a typical high frequency (HF) commercial off the shelf (COTS) limiter manufactured and tested by NexTek is presented to provide insight and understanding of … [Read more...]
Science Fiction from Childhood is Now a Reality. Thank You, EMC.
I grew up in the 90s in a small town in West Virginia. Everybody knew each other, everybody knew each other’s kids, and all of the kids spent time at each other’s houses in the summertime. When the heat and humidity turned oppressive, we’d spend the middle of the day inside, playing video games, listening to music, reading comic books, or trading baseball cards. … [Read more...]
EMC and Reliability in Flex PCB Cables Vs. Cable Assemblies
In military and aerospace systems, interconnect failure isn’t just an inconvenience; it can mean mission failure, equipment loss worth millions of dollars, or in the worst case, loss of life. Every connection between circuit boards represents a potential point of failure that must withstand extreme environmental conditions while maintaining signal integrity and EMC … [Read more...]
Bridging the Gap Between Theory and Practice With an EMC Demonstration System
INTRODUCTION Those graduating from university are often not trained in EMC. When they are, they are most likely trained very well in the theoretical aspects of EMC or at least some physics. However, they often lack the ability to apply these theories to gain a hands-on understanding of EMC principles. I have seen both junior and senior engineers … [Read more...]
CAL-P: The First Portable, Universal System for Functional Verification of EMF Sensors
In today’s landscape of electromagnetic field (EMF) measurements, ensuring the proper operation of measurement instruments quickly and directly in the field represents a major advantage for technicians. The growth of wireless applications, the expansion of broadband networks, and the need for compliance with international standards have made it essential to have … [Read more...]
You Measured What? 4 Must-Know Checks for Trusting Your S-Parameters
Verifying your trace S-parameters is more than just good practice—it’s essential for confident measurement, simulation, and design space exploration in modern EDA tools. Especially in high-speed digital systems where traces are long, applying a few key principles can provide valuable insights into your data and give you a head start in your design … [Read more...]
