SAT-1 MK-II

DESCRIPTION

The SAT-1 MK-II training system provides the basic principles and an in-depth demonstration of the concepts used in a satellite television reception system. The SAT-1 MK-II is designed as a self-contained, satellite television reception system and incorporates all elements necessary to perform the recommended experiments. The training system contains in addition to the main components of the reception system, a set of measuring instruments and accessories required for the accomplishement of all activities in the course of training.

EXPERIMENTS

Innovative Versatile Unique Advanced

TeleSimTeleSimTeleSimTeleSim

TeleSim is a unique software package for teaching Analog and Digital Telecommunications. The software affords every studentthe possibility to learn, design, understand, and evaluate scenarios in telecommunications through interactive on-screen simulations. TeleSim enables each student to explore and investigate the effects of various Telecommunications systems in a controlled problem-solving situation.

Unique TeleSim is the most advanced software product for teaching Telecommunications. Students in technical and vocational schools, universities or any training organization that uses advanced communications systems can use TeleSim. By using TeleSim, students easily grasp the relevant effects and framework of the material covered. TeleSim bridges the gap between theory and practice, restoring creativity in communication courses, and is the key to learning and success. Product Content TeleSim contains 12 independent modules organized into 2 courses (Analog and Digital), and an additional special course summarizing both. Each module allows students to learn, design and simulate different communication systems according to the material covered.

Innovative TeleSim caters to all student levels, from the inexperienced to the professional, as the relevant information is presented through four different learning techniques, which are: 1. Interactive design of an

integrated communication system

2. Solving step-by-step assignments

3. Tutorials 4. Animated theory

review. The student or the teacher can control these different modes of use. Simulation Lab TeleSim transforms a student’s regular PC into a sophisticated and functional laboratory. The software incorporates a powerful graphic simulator with analog and digital components and output devices. This allows for excellent experimentation by every student without the need for additional expensive equipment.
