Abstract

In the field of electromagnetic compatibility (EMC) testing, the environmental conditions under which electronic systems operate can play a critical role in the accuracy and reliability of test results. Standard EMC tests, performed in an EMC lab, typically focus on hardware performance under controlled conditions (e.g. room temperature). In real-world operation, however, the tested devices are often subject to additional influences such as temperature fluctuations and varying operational conditions that can significantly impact system behavior. This talk will focus on the importance of incorporating and combining these factors into EMC testing to ensure a more representative and robust characterization of electronic systems. 

Practical examples will be used to examine how factors like temperature shifts, moisture levels, and system load affect EMC, thus highlighting the need for a holistic approach to EMC testing. The audience will gain insights into how combined effects can influence a device’s EMC characteristics and how such effects should be accounted for during standard EMC testing.
