Advanced Communication Trainers (Analog & Digital)

ADVANCED COMMUNICATION TRAINING SYSTEM

(Analog & Digital Communication Experiment Trainers)

ACTS-1000

The ACTS-1000 trainer includes the basic & advanced modules to experiment on fundamental & higher level 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 a 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.

With the equipped power supply and signal unit, students only have to add the oscilloscope or Spectrum Analyzer, then they can complete various experiments independently.

ACTS-1000 is a open-modular design, it enables can be extended experimental range.
