摘要
介绍用相位计测量群时延的方法和技巧。通过分析和实验,给出了两种便于操作的测量方法,特别是利用第二种方法的测试技巧,把对时延的测量转换为对频率的测量,提高了测量准确度,使测量过程简便可行。
Introduced group delay measurement methods and techniques with phase meter. With analysis and experiment,two measnrement methods convenient for operation are proposed. Especially in the second method, delay measurement is converted into frequency measurement to improve measurement accuracy and make the process simple and feasible.
