Transmission Line Trainer

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.
