摘　　要：本文介绍了矢量网络分析仪动态范围的定义极其相关概念,讨论了提高网络分析仪动态范围的几种方法,其中外加放大器和衰减器组合法,能够最大限度提高动态范围。采用放大器,就必须考虑接收机的烧毁电平和压缩电平,采取适当的措施进行校准,以便提高系统测量准确度。This paper introduces the Vector Network Analyzer the definition of dynamic range and its related concepts discussed improve network analyzer dynamic range of methods, including external amplifier and attenuator combination method to maximize dynamic range. Use amplifiers, receivers must consider the level and burned compression level to take appropriate measures calibration, in order to improve measurement accuracy of the system.
