Diactic equipment with panels made in metal case with bench support and the electrical scheme on the front panel. 
This trainer shall be designed to guide the student to the comprehension and testing of the physical principles of the propagation of electrical signals on transmission lines and as an introduction to the use of the lines as a main element in communications systems.
This trainer shall include the devices and accessories required for realizing significant experiences on low frequency transmission lines.
These devices and accessories shall allow the student to acquire a clear and essential sight of the items related to the signal transmission along the lines.

Technical Features:
The trainer shall be composed of a module with 100 meters of coaxial cable with intermediate plugs, every 25 meters, and with termination variable resistors.
With this trainer it must be possible to perform the following experiments:

• Measuring the characteristics of a line 
• Measuring the attenuation of a line 
• Frequency characteristic of the line 
• Input impedance of the line 
• Stationary waves 
• Signal phase shift along the line 
• Fault localization within the line 
• Line in pulsed condition
• It must be mounted on an insulated didactic module, it must  show a schematic diagram and 2 mm terminals for the electrical connection
• The board must be supplied complete with a set of stackable, plug-in cables of suitable lengths and colors and with a training manual.
