Speaker: Brian Avenell (RF Design Engineer, National Instruments)
Like most RF measurements, the mechanics of making a noise figure measurement are the easy part. However, determining the measurement uncertainty can be challenging. Whether you are using the popular Y-factor or cold-source technique, not understanding measurement uncertainty can result in inaccurate measurements. At this session, review the more important contributors to measurement uncertainty when measuring noise figure. In addition to exploring the sources of uncertainty and their relative importance, examine common mistakes in the noise figure measurement process that can lead to accuracy issues.
