It can be complemented by an extensive range of add-on features and options for mission-specific customization. With its enhanced robustness, the R&S FNH delivers lab-grade … [Read more...]
Component Reliability in Aerospace Systems
Aerospace electronics are expected to run for long lifetimes with high uptime, and many systems are designed around Mean Time Between Failures (MTBF) targets exceeding 10,000 hours of continuous operation. When looking at simple electrical ratings or descriptions, many components will look acceptable, but they can fail because the components were not structurally … [Read more...]
The 40-Week Problem: Why Medical Device EMC Failures Cost the Most When They’re Caught Late
The fix is rarely the expensive part. The timing is. The Fix That Costs 40x More in Week 40 Than in Week 4 Here's a pattern I've watched play out on program after program. A device sails through internal bench testing. Engineering is confident. The unit goes to the test lab for formal IEC 60601-1-2 immunity testing, and at 3 V/m radiated RF susceptibility, … [Read more...]
The Role of an EMC Engineer in Product Development
Coming out of college, whether it’s electrical, mechanical, software, or any other engineering discipline, a lot of young engineers picture themselves as Tony Stark building an Iron Man suit or as Mark Watney getting stuck on Mars and engineering his way back home to Earth as their future career. What many young engineers don’t quite understand is that engineers … [Read more...]

How to Build a Reliable TDR from S-Parameters to Reduce EMI Worries
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 … [Read more...]

EMC for Missiles
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. Emphasis … [Read more...]
What’s New in MIL-STD-461H
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. Although I … [Read more...]
