DEVICE FOR MEASURING ELECTRIC CHARACTERISTIC OF CABLE ASSEMBLY, PROGRAM FOR MEASURING ELECTRIC CHARACTERISTIC OF CABLE ASSEMBLY, AND METHOD FOR MEASURING ELECTRIC CHARACTERISTIC OF CABLE ASSEMBLY

摘要

A measurement device for measuring a cable assembly propagation delay time. The measurement device superimposes and displays temporal change characteristics of two reflection coefficient amplitude values obtained by successively connecting a connector having one end open to a conversion adapter of the measurement device and a connector having one end short-circuited, so as to calculate the time of the branching point position. The measurement device superimposes and displays temporal change characteristics of two reflection coefficient amplitude values obtained by successively connecting a cable assembly connected to a connector having one end open at the far end and a cable assembly connected to a connector having one end short-circuited at the far end, so as to calculate the time of the branching point position. Furthermore, a difference between the times obtained is divided by two so as to obtain a propagation delay time. Since it is easy to read the branching point position, it is possible to minimize the measurement error caused by a person who measures.
