Description

Satellite communication Trainer IT-703 demonstrates the basic concept of satellite communication. The trainer is based on three parts namely Uplink Transmitter (IT-703A), Transponder (IT-703B) and Downlink Receiver (IT-703C). This trainer is capable of transmitting two Audio channels and one Video channel simultaneously. All parts of the trainer are self contained providing the student with microphone interface tone generator and data generator etc. PC software is also available for PC-PC data transmission using satellite link.
