Effectively Addressing Measurement Uncertainty in Electromagnetic Compatibility Testing (Part 1)
Time:
Monday, 01/Sept/2025:
2:20pm - 3:50pm
Location:Room 108
120 seats, Tower 44, 1st floor
Session Abstract
This workshop convenes leading experts in measurement uncertainty, emphasizing its vital importance in electromagnetic compatibility (EMC) testing. Participants will explore fundamental concepts of measurement uncertainty and gain practical methodologies for performing calculations in commercial test laboratories. The session will cover effective data collection techniques and streamlined calculation methods. One segment will focus on estimating uncertainty specifically for antenna measurements, in accordance with the Guide to Uncertainty in Measurements. Additionally, a discussion will address the challenges of measuring uncertainties within a multipurpose robotic antenna test system.
The workshop will also provide insights into measurement uncertainties related to high-altitude electromagnetic pulse (HEMP) and high-power electromagnetic (HPEM) testing. This will include an overview of various test sites, instrumentation, and the evaluation of normative specifications against both civil and military standards. Lastly, participants will be introduced to Polynomial Chaos Theory as a technique for uncertainty propagation and sensitivity analysis in power electronic circuit design. The session will demonstrate how stochastic simulations can effectively integrate uncertainties from multiple sources.
Overall, this workshop aims to equip attendees with the essential knowledge and tools to navigate the complexities of measurement uncertainty in EMC testing, enhancing their understanding of its implications in both commercial and research environments.
