Transmission Line Trainer For Electrical Lab Training

Experimental training board has been designed specifically to study the various parameters in transmission line. Practical experience on this board carries great educative value for science and engineering students. Object:To measure the following : Measuring the characteristics of a line Measuring the attenuation of a line Measuring the Input Impedance of the line Phase displacement between the current & voltage at input of line Frequency characteristic of the line Study of Stationary Waves Signal phase shift along the line Fault localization within the line Line under pulsed condition. Features:The board consists of the following built-in parts : 4 Nos. Coaxial Cables 25 meters each, total Transmission line 100 metres. Two potentiometers for impedance matching. Sine/Square wave Signal Generator having frequency 40KHz to 4MHz, in two bands 40KHz to 400KHz & 400KHz to 4MHz. A SPDT switch to select either sine or square wave. A SPDT switch to select frequency either high (400KHz to 4MHz) or low (40KHz to 400KHz). A potentiometer to vary frequency high (400KHz to 4MHz) or low (40KHz to 400KHz).
