As hospitals fill with wireless devices—from patient monitors to smartphones—radio frequency interference threatens medical device performance and patient safety. This article explores the critical testing methodologies, regulatory requirements, and risk management strategies manufacturers need to ensure their wireless medical devices work reliably in today's crowded spectrum environments.

Aircraft power systems endure dramatic electrical events—voltage surges, frequency shifts, and sudden dropouts during engine transitions. Power line testing ensures avionics can withstand these harsh conditions, from flight-critical computers that must survive 50ms power failures to everyday equipment that keeps passengers comfortable at 30,000 feet.

As electromagnetic environments grow more complex, RADHAZ assessments have become critical for military safety. Radio frequency radiation can ignite fuel, trigger explosives, and harm personnel. This article explores the three primary hazard areas—HERP, HERO, and HERF—examining how assessments protect against dangers from both high-power radars and low-power transmitters in modern military operations.

Harmonic comb generators are essential EMC lab tools that produce harmonically-related signals for chamber verification and troubleshooting. Learn why every test lab needs one, how to build a simple DIY version for under $50, and discover the best commercial options with unique features. From measuring cable resonances to portable chamber validation, these versatile devices belong in every EMC engineer's toolkit.

Spectrum analyzers are essential for EMC testing—but only when used correctly. From setup and calibration to antenna selection and data interpretation, this guide covers best practices to ensure accurate measurements and smooth compliance with regulatory standards.

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.

The FCC is moving to withdraw recognition from seven test laboratories in a sweeping enforcement action. This unprecedented step, stemming from new rules adopted in May 2025, marks a significant shift in how the Commission oversees its certification and compliance testing infrastructure.

Can you use everyday electronics on an aircraft, or do they need special military-grade testing? Patrick Andre examines when commercial off-the-shelf equipment works fine versus when it could fail catastrophically in demanding environments like military aircraft and helicopters.

Don MacArthur explores essential EMC test chambers—from anechoic to reverberation types—used across industries like automotive, aerospace, and consumer electronics. Learn key design considerations including material selection, shielding effectiveness, and applications ensuring electromagnetic compatibility compliance.
