Abstract: Measurement of phase noise has become important in designing and developing systems for communications which pervade so much of our daily life. Without good, low phase noise oscillators in systems such as mobile telephone systems, the levels of interference experienced by users would become
Spectrum Analyzer Tutorial Includes. Phase noise is a key parameter for many systems, and measuring it accurately is of great importance. One of the easiest methods to measure phase noise is to use a spectrum analyser using what is termed a direct measurement technique.
Extracting electronic signals from noise is a challenge for most electronics engineers. As engineers develop cutting edge radar and communications systems, where extreme processing is used to obtain the maximum amount of information from the signal, phase noise is the little understood nemesis limiting system

The first question that is often asked is; What is phase noise? In the main, when we are talking about phase noise we are talking about the frequency stability of a signal. We look at frequency stability from several view points. Many times we are concerned with the long-term stability of an oscillator over the observation time
Fortunately, the noise-to-phase transfer function of oscillators is still linear, despite the existence of the nonlinearities necessary for amplitude stabilization. In addi- tion to providing a quantitative reconciliation between theory and measurement, the time-varying phase-noise model presented in this tutorial identifies the
