时域分析法可用于测量传输线沿着的阻抗值,并可用于识别器件在时间或距离上的问题,如不连续性。时域测试结果可更直观、直接地了解被测器件(DUT)的特性。与其他测量技术相比,通过将每个不连续性的影响显示为时间或距离的函数,它提供了有关传输系统宽带响应的更有意义的信息。使用矢量网络分析仪(VNA)进行时域分析。目的是为工程师提供频域背景知识,并深入了解如何从频域数据(S参数)创建时域显示,以及如何将时域显示应用于RF系统中的常见问题。
Time domain analysis is useful for measuring impedance values along a transmission line and for identifying a device problem in time or distance such as discontinuity.The time domain testing result provides a more intuitive and direct look about the characteristics of the device-under-test(DUT).Compared with other measuring techniques,it gives more meaningful information concerning the broadband response of a transmission system by showing the effect of each discontinuity as a function of time or distance.This paper will focus on the time domain analysis using the vector network analyzers(VNAs).The intent is to provide engineers with frequency domain background and an in-depth view of how a time domain display is created from the frequency domain data(S-parameters)and how to apply the time domain display to common problems in RF systems.
