Shielded balanced and coaxial transmission lines. Parametric measurements and instrumentation relevant to signal waveform transmission in digital service
Abstract
The impulse and step responses of a shielded cable using time domain terminal measurements and a physically based mathematical model for the transmission line properties of the cable are determined. A computer controlled time domain measurement system was implemented using the automatic pulse measurement system. Data are also developed for the frequency domain complex propagation function (attenuation and its related minimum phase shift). The method is applied to 12 shielded paired conductor (balanced) cables and 5 coaxial cables. Time domain responses are presented for three nominal cable lengths, 60 m (200 ft), 150 m (500 ft), and 300 m (1000 ft).
