FEATURES The db-tech, DB-3401 Transmission Line Trainer investigates transmission lines. The configurable transmission lines allow realistic studies of short, medium and long-distance transmission lines under variable load and power factor conditions. The console is divided into two control panels, each with detailed mimic diagrams. The upper panel has a transmission line, and the lower panel a control panel. The lines may be loaded by the resistive, loads. The effects can be monitored by instruments at the send and receive ends of the transmission lines.   SPECIFICATIONS 01. 4 Nos. Coaxial Cables 25 meters each, total Transmission line 100 metres. 02. Two potentiometers for impedance matching (0-100 Ohms). 03. Sine/Square wave Signal Generator having frequency 40KHz to 4MHz, in two bands 40KHz to 400KHz & 400KHz to 4MHz. 04. A SPDT switch to select either sine or square wave. 05. A SPDT switch to select frequency either high (400KHz to 4MHz) or low (40KHz to 400KHz). 06. A potentiometer to vary frequency high (400KHz to 4MHz) or low (40KHz to 400KHz). 07. A potentiometer to vary amplitude. 08. BNC connector to connect input. 09. Adequate no. of other electronic components. 10. Mains ON/OFF switch, fuse and jewel light. 11.
