Minimize Your Y-Factor Noise Figure Measurement Uncertainty

Like most RF measurements, the mechanics of making noise figure measurements is the easy part. 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. This presentation will review the more important contributors to measurement uncertainty when measuring noise figure. In addition to the sources of uncertainty and their relative importance, the common mistakes in the measurement process will be shared. Following the presentation, you will understand the best practices for making a quality noise figure measurement with low measurement uncertainty.
