03.23.22 -- Phase Noise Fundamentals And Measurements



Understanding Phase Noise Fundamentals

A stable frequency source is a common requirement for many electronic and most RF devices. Phase noise is the term used to describe measurements of the short-term frequency stability of these sources. This article provides a technical introduction to phase noise concepts as well as an overview of how phase noise is measured and reported.

Mastering Phase Noise Measurements

Whether you are new to phase noise or have been measuring phase noise for years, it is important to get a good understanding of the basics and to learn of new measurement techniques to improve your designs.

Residual Or Additive Phase Noise Measurements

This application note reviews the fundamentals of residual or additive noise. It addresses measurement techniques for determining the amplitude (AM) and phase noise added by two-port devices such as: amplifiers, mixers, block frequency converters, multipliers, dividers, and frequency synthesizers.

Understanding Pulsed Phase Noise Measurements

For both communications and radar systems, one of the key RF parameters that limits system performance is phase noise. This application note focuses on phase noise measurements for pulsed RF carriers and addresses some of the physical limitations relating to pulsed phase noise measurement.

Improving Phase Noise Measurement Speed

For automated test applications, measurement time is often as important as the quality of the measurement. However, several measurement settings drastically affect measurement speed. This paper discusses these settings and provides suggestions on improving your overall measurement speed.
