Performing Differential Noise Figure Measurements

Brand Logo Statement Stacked Rgb

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.
