Application of bridge methods for measuring the characteristic resistance Zw and the attenuation constant α of symmetrical and coaxial cable circuits

Abstract In this article, it is shown an experiment of using Impedance bridge for measuring the basic parameters of a symmetrical cable chain. The appropriate mathematical formulas are taken out and using a simple program, it is calculated the basic primary R, L, G, C and secondary parameters Zw and γ of a symmetrical or coaxial cable chain process of studying them. Results of calculations by the method are brought and compared with directly measured values for the module of the characteristic resistance |Zw| and the attenuation constant α..
