Phase locked loops and other signal generation techniques such as frequency synthesis.

Online RF Technology Certification

Author: 

Besser Associates

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.

Phase Noise Measurement Methods and Techniques (2012)

Author: 

Kay Gheen, Keysight

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.

Choosing a Phase Noise Measurement Technique

Author: 

Terry Decker and Bob Temple

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.

HP Phase Noise Seminar Notes

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.
