The trainer includes the basic & advanced modules to experiment on fundamental & higher level of analog & digital topics of a telecommunication course. The purpose of the modules is to enable the student to acquire a clear experimental view of the basic & advanced concepts and familiarization with the operative aspects of the work in the telecommunication laboratory. This trainer combined the modules with experimental circuits. It can offer the beginner complete courses of basic & advanced communication in 18 experiments modules: 8 Digital & 10 Analog Experiments Modules with the optional power supply and signal unit, oscilloscope or Spectrum Analyzer, then they can complete various experiments independently.
