Transmission Line Trainer 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.
