Understand how measurement uncertainty affects radiated emissions tests and how to reduce it.
This technical report explains why EMC tests have uncertain results and how these uncertainties arise in practice. It focuses on radiated emissions and the many factors that can influence measurements, from test setup to instrument performance. Readers will gain a practical view of how to quantify and manage these uncertainties to support compliance decisions.
- Identify the main sources of uncertainty in radiated emissions measurements and how they are evaluated.
- Learn how combined and expanded uncertainties are calculated and interpreted for compliance testing.
- Explore different test facilities and methods, including open-area test sites, anechoic chambers, and specialty devices like TEM, GTEM, and three-loop systems.
Ideal for engineers, technicians, and students working in EMC testing who need a grounded, applicable view of uncertainty and its impact on meeting emission limits.
