How To Measure Additive Phase Noise Of Amplifiers Using 7000 Series 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 discusses the various trade-offs in a phase noise measurement of a pulsed RF signal and how easy it can be performed using the 7000 series signal source analyzer.
