Performing Differential Noise Figure Measurements

In recent years, numerous improvements have been made in noise figure measurements through better algorithmic understanding of the measurements, more sensitive receivers, and less error-prone methods of processing noise power measurements. Anritsu has incorporated a number of these improvements in the single-ended Noise Figure Measurement Option of the VectorStar vector network analyzer (VNA) platform.

This application note offers insights into and examples of performing differential noise figure measurements.
