Wondering how electronics pass EMC compliance? This guide breaks down essential standards from CISPR, IEC, FCC, and more—plus real-world examples from smartphone makers, automakers, and medical device manufacturers. Learn the testing requirements, documentation needs, and practical techniques companies use to ensure their products won't cause or suffer from electromagnetic interference.

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.

Effective bonding is crucial for EMC success, but requirements vary by purpose. NASA-STD-4003A defines five bond classes—from static control to lightning protection—each with different impedance and current needs. Understanding which class applies helps engineers design appropriate bonding schemes rather than over- or under-engineering connections.

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.

Discover why copper shields outperform steel at low frequencies but steel dominates at high frequencies. This practical guide presents simplified formulas for calculating electromagnetic shielding effectiveness, revealing the surprising crossover point at 4200 Hz where material performance flips.

EMI filters are essential electronic components that eliminate unwanted electromagnetic interference, ensuring devices operate reliably without disrupting nearby equipment. From low-pass to common-mode chokes, these filters reduce emissions, enhance immunity, and ensure regulatory compliance. Proper design requires identifying noise sources, selecting quality components, and strategic placement for optimal electromagnetic compatibility.

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.

The IEEE EMC Society is advancing three shielding effectiveness standards: one for large enclosures, another for smaller boxes, and a new standard for portable device pouches. Measuring electromagnetic shielding in space-constrained environments presents significant technical challenges that require innovative solutions.

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.
