This online program has been designed for applications, production, manufacturing engineers and technicians as well as other professionals who need to have a solid background in the fundamentals of working with RF and wireless products. This four part program provides a thorough understanding of RF analytical tools, communications signals, RF devices and test instruments. Starting with basic analytical tools such as the decibel scale, S-parameters and the Smith Chart, this program covers test instrumentation, RF components, and modulation.

Tutorials page from the IEEE Ultrasonics, Ferroelectrics and Frequency Control society website. The page lists several free tutorials that are available to download on topics such as low noise oscillators, phase noise, and crystal resonators.
These slides from a webinar presentation give a detailed overview of the principles of measuring phase noise. The underlying relationships between phase noise spectral energy, demodulated phase noise, frequency etc. are described. The presentation also includes a description of the "modern" definition of phase noise along with current measurement techniques.
These seminar notes give a good discussion of the principles of phase noise. Specifically the authors describe the difference between measuring phase noise directly or using phase/frequency demodulation techniques. The notes describe details about the limitations and equipment performance requirements for making phase noise measurements using a variety of techniques. Since these notes are from an older archive, the latest techniques involving the use of correlation are not described.
Converting a phase noise specification to jitter is often desirable for digital designers and others used to working in the time domain. This app note describes the principles of phase noise as well as deriving the conversion to jitter. A useful list of references is also included.
These notes from a seminar given by HP in the mid-80's serve as a useful reference for some of the fundamental relationships governing phase noise. Needless to say, some of the most recent techniques in phase noise measurements are not represented, but the mechanisms that generate phase noise are described in useful detail.
This is a detailed article comparing phase noise measurement techniques and their advantages and disadvantages. You will need to be a member of the Microwave Theory and Techniques society of the IEEE to view the article for free. A purchase option may be available if you are not a member.
