Abstract
The characteristic evaluating system of the present invention includes: a cable-driving transmitter transmitting a signal to one end of a cable to be measured; a load connected to the other end of the cable; a probe detecting a common mode current of the cable; a receiver receiving a signal detected by the probe; and a controller controlling the cable-driving transmitter, the load, and the receiver. The cable-driving transmitter is constructed such that a plural transmission condition is selectable when transmitting the signal. The load is constructed such that plural termination conditions corresponding to the signals transmitted to the cable is selectable. The characteristic of the cable is measured by scanning relative positions of the probe and the cable in a longitudinal direction of the cable.
