EMC Compliance Testing with Prescan Analysis Tools
应用文章
Today’s fast-paced, high-growth electronics market requires electromagnetic compliance (EMC) test facilities to develop shorter product test cycles while maintaining test accuracy. Commercial test requirements recommend emissions prescan methodologies to help reduce overall test times and improve facility throughput. However, these measurements can introduce frequency and amplitude errors into the suspect list. As a compliance test engineer, you need to understand the benefits and challenges associated with prescan data to ensure that final measurements are being made at the correct frequencies.
This application note provides an overview of the errors associated with prescan analysis and how to overcome them using spectrum analysis and intermediate-frequency (IF) spectrum monitoring capabilities.
