多端口网络分析仪只需使用幅值指示器便能够在宽频段内高准确度地测量终端式或通过式设备的各种参量。当研制这类网络分析仪时,研制人员面临的任务是从各种可能的多端口电路中选择那些能够实现测量变换器功能的电路,这取决于多端口电路固有参量的数值及其相互关系。因此,应当对各个参量提出合理的要求并规定出对多端口测量变换器 Multi-port network analyzers simply use the amplitude indicator to accurately measure various parameters of a terminal or pass-through device over a wide frequency band. When developing such network analyzers, the task faced by developers is to select from a variety of possible multiport circuits those circuits that can function as measurement transducers, depending on the value of the intrinsic parameters of the multiport circuit and their interrelationships. Therefore, each parameter should be made reasonable request and provides for multi-port measurement converter
