In this paper, we propose a new load impedance measurement system based on time-frequency domain reflectometry. The proposed system was able to measure the load impedances that were realized with using various terminal resistors and connected at the end of a cable. The experimental results show that the proposed system allows us to know where the connected terminal resistor is on the cable, and how much the impedance of the terminal resistor is. Through real experiments, it is possible for the proposed system to acquire more accurate results in wide range of impedance than conventional commercial time domain reflectometry instrument.
