Experimental Teaching System for Communication Principles

Product Introduction
The course "Principles of Communications" is one of the most important professional foundation courses in the fields of communications, electronics, and information. The experimental platform can be used as a teaching platform for communication engineering, electronic information, computer communications, etc. in colleges and universities. It focuses on the generation, transmission, and demodulation technologies and testing methods of various communication signals in communication systems, so that students can quickly master and become familiar with the basic theories and concepts of communication systems .






Features
1. Adopting modern open design concept, it integrates verification experiment and autonomous experiment, and the secondary development experiment function is more powerful and more adaptable to user requirements.
2. It comes with analog signal source and clock/digital signal source, built-in power supply +5V, +12V, -12V, no external power supply is required.
3. The comprehensive experimental functions between the experimental box modules are powerful. A single experimental box can realize simplex communication; two experimental boxes can realize duplex communication. At the same time, it can also complete networking and various signal optical fiber transmission and module digital exchange experiments between optical fibers and program-controlled switches.
4. The experimental box is equipped with communication E1 interface, 2M interface, and RS232 interface, which can complete communication experiments between PC and experimental system.
