Analog Communication Trainer

The Analog Communication Trainer includes basic and advanced modules to experiment on fundamental and higher level analog and digital topics of a telecommunication course. The purpose of the modules is to enable students to acquire a clear experimental view of basic and advanced concepts and familiarity with laboratory operations.

This trainer combines modules with experimental circuits and offers complete courses of basic and advanced communication in 8 analog experiment modules. With optional power supply and signal unit, oscilloscope or spectrum analyzer, students can perform various experiments independently.
