Abstract

In this paper, TFDR-based impedance measurement methodology proposed by YongJune Shin et al. (2003) is implemented. TFDR allows one to compensate the error of impedance measurement caused by distortion in transmission line by measuring phase difference and local frequency offset between the input and the reflected signals. The implemented experimental system is composed of the TFDR as a main framework and terminal resistor as load impedance. The experimental results imply that it is possible to acquire more accurate complex impedance with comparatively lower performance instruments than those of the conventional commercial TDR
