"ET-893 Flat Screen Digital Terrestrial Television Training System

The ET-893 ET-893 block diagram shows through an intuitive way the differentstages that compounds the flat screen receiver. is a suitable equipment for the learning of the flat screentelevision sets operation equipped with TFT-LCD and Plasma technology that allows the student to become familiar with the more
advanced technological innovations, as well as Digital Terrestrial Television (DVB-T). The trainer includes a failures generation module.The >
With a wide number of test points, makes possible a thorough analysis and tracking of the electrical signals in thedifferent blocks from the receiver. All the points of test are protected against accidental short-circuits. By means of
the failures module it is possible to simulate the more frequent failures than they can take place in the receiver in
order that the student learns to carry out methods of diagnosis and trouble-shooting.Specially attention has been dedicated to develop a fully functional design with a small size. TERRESTRIAL TV TFT-LCD RECEIVER BLOCK DIAGRAM - Screen size 20''.- 4:3 format.
