EMC Bench Notes: Pre-Compliance Testing for Radiated Emissions, Part 4 – Measurement Software

This month's EMC Bench Notes reviews three affordable pre-compliance measurement software options that can simplify and automate the process of conducting in-house radiated emissions testing, saving time and costs compared to manual methods.

Standards Practice: Why So Many Immunity/Susceptibility Tests?

This detailed overview of electromagnetic immunity testing across defense, aerospace, and automotive industries explains why different sectors require unique standards to protect equipment from various electromagnetic threats and interference.

Military and Aerospace EMC: The Currents of EMI

Understanding current flow patterns is crucial in EMC engineering, particularly the distinction between Common Mode and Differential Mode currents. Controlling current paths and providing local return paths helps reduce electromagnetic interference and improve immunity.

Product Insights: Understanding Capacitor Frequency Characteristics

Mastering capacitor behavior is crucial for noise control in electronics. Understanding impedance variations with frequency, along with ESR and ESL components, helps engineers design effective filters. The piece explains how capacitors "dance" with frequencies to manage unwanted noise.

Product Insights: Why Do Ferrites Never Seem to Work When We Need Them To?

Ferrite beads may fail to suppress RF emissions due to misidentified noise sources, high circuit impedance, outdated advice, or incorrect ferrite selection. Careful analysis and appropriate application are crucial for effective EMC compliance.
