摘要
幅相一致性和幅相线性是影响接收机性能提高的重要因素,也是精确测试的难题。本文在简要介绍矢网测试原理的基础上,给出了利用安捷伦公司矢网N5242A测试上述两项指标的方法,给出了测试结果。实际测试结果表明利用矢网测试接收机的幅相一致性和线性是高效可行的。此外,文中还提出了利用矢网测试应该注意的问题。
Coninstency and linerarity are very important to limit the improvement of the performance of receiver ,with which are very difficult to make a precise measurement. In this paper based on introduction of principles of vector network analyzer（VNA）, provide a method for precise measurement which are using VNA N5242A made in Agilent. The results indicated that the method based on vector network analyzer is feasible, efficacious and accurate. At last, some problems were provided in precise measurement.
