Enhancing EMC Testing with Digital IF

Application Notes

Introduction

With today’s accelerating business environment and development cycles, EMC measurement facilities that offer rapid test turnaround and high throughput, while still providing accurate and reliable measurements, will achieve greater success. Modern EMI receivers and spectrum analyzers used for compliance and precompliance testing employ digital intermediate-frequency processing technology (digital IF) for signal analysis. Not only does digital IF boost overall instrument reliability, it enables improved amplitude accuracy, increased measurement throughput, and reduced dependence on operator experience level. These benefits result in higher efficiency and lower operating costs. This application note will discuss the differences between analog and digital IF architectures and explain how digital IF enhances both compliance and precompliance measurement processes.
