标准摘要
[中文适用范围]： 涵盖放大器等子系统或用于模拟卫星地球站的子系统组合。处理回波损耗、输入和输出电平、幅度/频率特性、群延迟/频率特性、非线性 [外文原描述]： Deals with basic measurements which are equally applicable to a sub-system such as an amplifier, or to a combination of sub-systems assembled to simulate a satellite earth station. Methods of measurements are described for the following parameters: -input and output impedance (return loss); -input and output levels; -baseband gain or loss; -amplitude/frequency characteristic; -group-delay/frequency characteristic; -non-linear amplitude distortion; -differential gain and phase distortion.
