How to Measure Additive Phase Noise of Amplifiers Using Signal Source Analyzers

Source: Berkeley Nucleonics Corporation

Additive (or residual) phase noise comes from the self-phase noise of a component as a signal passes through it. It’s important to be able to measure this type of residual noise contribution of each single component part of a system design. BNCs 7000 series measures both absolute phase noise and the additive phase noise of non-self oscillating DUTs such as amplifiers, transmitters, mixers, and prescalers. This application note explains how you can use the 7000 series of signal source analyzers to measure this residual noise.
