An assessment on the accuracy of time-domain reflectometry for measuring the characteristic impedance of transmission lines
نویسنده
چکیده
An assessment of time-domain reflectometry (TDR) for measuring the characteristic impedance ZTL of transmission lines is performed. The assessment includes the accuracy of measuring ZTL as a function of TDR electrical impedance Zo, the ability to measure impedance perturbations as a function of ZTL and Zo, and the ability to differentiate between transmission lines of similar ZTL. The information presented herein wiDbe especiaUy useful for those using SOn TDR systems to characterize transmission lines having characteristic impedances less than about 30 n.

Conventional fault location methods using voltages and currents of one terminal are not applicable to multiterminal transmission lines. So far some techniques have been presented to solve fault location problem for multi-terminal transmission lines. In these methods, lumped or distributed frequency domain models of transmission lines have been used. In multi terminal lines, faulty section shoul...
متن کاملTDR and VNA Techniques for PCB Characterization
A uniform transmission line is described electrically by a characteristic impedance and a time delay. From the length of the line and the time delay, the effective dielectric constant can be extracted. Two instruments are commonly used to measure these properties, a time domain reflectometer (TDR) and a vector network analyzer (VNA). In this paper, these techniques are reviewed. We show that an...
