W130 — Understanding Phase Noise in RF and Microwave Calibration Applications.
Most RF and Microwave calibration practitioners are aware that phase noise can be an important characteristic of signal sources, signal analyzers, systems, and components. However, they are often not aware of the underlying causes of phase noise, its impact on the performance of equipment and systems, or the significance of phase noise in a variety of calibration tests and applications. This paper presents a broad overview of phase noise, its causes, and its impact on
modern instrumentation and systems. It also discusses in more detail the relevance of phase noise and test equipment phase noise characteristics in the calibration environment – in particular for the selection of calibration standards and performing calibration procedures.
