标准摘要
[中文适用范围]： 描述了通过使用配备反射测试装置（电桥）的矢量网络分析仪测量频域中的回波损耗并将结果转换为时域图来确定射频电缆阻抗规律性的测试。 [外文原描述]： describes the test which determines the regularity of impedance of r.f. cables by measuring the return loss in the frequency domain using a vector network analyser equipped with a reflection test set (bridge) and transferring the results into the time domain by using the Inverse Discrete Fourier Transformation (IDFT).
