The Measurement of Group Delay and Phase Dely in Network

REN Ya fen, XU Hai yan, MEI Lin ling (No.808 Institute of SAST, Shanghai 200090, China)  
According to characteristic of Network transmission, this paper discusses relations between group delay and phase delay mainly as well as analysis the principle of its working. In order to meeting actual engineering test requirements, A equipment which specify to measure Network's group delay time under microwave continuous signal stimulation, and another equipment used under pulse modulation conditions are designed. Finally all technique points and testing errors are presented in general.
