Measurement for phase noise using spectrum analyzer and the analysis of its measurement uncertaintyLiu Yanyan,Xu Shiwei,Xuan Zongqiang1. School of Mechatronics, Xidian University, Xi＇an 710071; 2. School of Microelectronics, Xidian University, Xi＇an 710071Abstract:The phase noise is a very important specification in electronic measurement, and it can decide the performance of the overall system. There are several methods to measure the phase noise. However, each method has advantage and disadvantage. Thus, it is of great importance to choose an appropriate test method according to the practical need. This paper mainly deals with this issue. It discusses a measurement method for phase noise using spectrum analyzer by doing experiment and analyses the test data using the theory of measurement uncertainty.[著者文摘]
