Abstract - Over the past years, Phase Noise has become critical parameter for the performance of many systems ranging from cellular receivers, highspeed digital systems, and target detection and identification systems. Currently, Phase Noise is a very important design parameter for all top-of-the line signal generators and frequency synthesizers. In this seminar, Phase Noise will be defined and explained in simple terms. The various methods and concepts used to quantify Phase Noise in time and frequency domains will be defined and explained. The frequency domain approach in quantifying and measuring Phase Noise will be will be emphasized and explained in detail because it is the most accurate and repetitive approach for characterizing Phase Noise. Different practical methods used in measuring Phase Noise will be explained and compared. The design of commercially available test instruments is also explained and compared to understand merits and limitations.

Dr. Salem Marougi is with the Signal Sources Division of Keysight Technologies. He has over twenty-two years of experience working on various RF and Microwave assemblies and products.
