| 摘 要： | 相位噪声是电子测量中的一个重要指标,相噪指标的好坏直接影响着整个系统的性能。测试相位噪声的方法有几种,然而,每种测试方法都有各自的优缺点。因此,根据实际的需要来选择适当的测试方法就尤为重要。本文主要是通过实验来讨论用频谱分析来测量相位噪声的方法,并对其测量的结果,应用不确定度理论给出了相应的测量不确定度的分析。

| Abstract: | 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. |
