Digital Communications Training Systems



The Digital Communications Training Systems form a complete and operational communications program, as well as a powerful educational tool. They use IC technology to implement signal modulators and demodulators that operate at standards employed in digital communications technology.

The systems are equipped with various features that enhance hands-on learning: easy access to test points, fault-insertion switches, safety shielding and full short-circuit protection, silk-screened block diagrams and component labels, and fully-integrated courseware. The Digital Communications Training Systems allow instructors to achieve a wide range of educational objectives at various levels.

The modularity of the systems allows students to quickly assemble a functioning communications network by using coaxial cables. Fully compatible signal levels and protocols are fed among modules from front panel connection points. Because the system is composed of prewired, functioning modules and connections between modules are made with shielded cables, the routing and trimming of student connections do not affect system performance and measurements. Important test points or test busses are brought out to 9-pin connectors on the front panels of modules for easy access.
