2024 EMI/EMC Summit

Topics covered

BCI System Demonstration

The BCI system presentation will show how to calculate and measure a BCI system for ISO 11451, MIL-STD-461G, or IEC 61000-4-6. We will work backward given a test level, known transfer impedance from industry probes and equipment, and then follow good practices to size generators and amplifiers accordingly. After going through the calculations, the presenter will give a quick demonstration using industry software and show the class how close the measurements are versus actual using various supplied equipment.

Practical Comparisons of Individual EMC Requirements

This discussion will provide a detailed comparisons of individual requirements and test methods in MIL-STD-461 with available commercial (non-military) standards that are the most similar. The differences in limits and test methodology will be identified and their potential significance will be discussed. Guidance is provided on judging the acceptability of a particular commercial standard for specific applications and if the testing conducted commercially can give an indication of compatibility to MIL-STD-461.

Lightning Indirect Effects and Fuel Systems Test Methods

This discussion will provide detailed insights to lightning indirect effects and lightning fuel system test methods in the SAE ARP5416 commercial aircraft standard. Lightning indirect effects test methods to be discussed include full aircraft tests to measure cable bundle lightning induced transients and bench tests to evaluate equipment and systems. Lightning fuel system test methods to be discussed include aircraft wing tests to map fuel system lightning currents and flammable fuel vapor tests to evaluate fuel tank coupon specimens, fuel system components, and complete fuel tanks.

Applying Machine Learning Techniques to Advanced EMC Test Sites

Zhong Chen will provide insights into applying machine learning techniques to advanced EMC test sites.
