A SIGN OF QUALITY PRODUCT OMEGA TYPE DB-10
TELEVISION DYNAMIC DEMONSTRATOR
OMEGA TYPE DB-10 Dynamic Demonstration Board has been designed specifically for the study of Television Dynamic Demonstrator. Tdemonstrator incorporates the most modern technology, using ICs and has been designed with a view to give a live demonstration of the workingsolid state Multi Channel B & W TV Receiver to students. All the PCBs mounted with components of the different sections are well arranged on a boof size 48" x 39" with full schematic diagram. A neat block diagram and different wave shapes are also given on the board. The board is absolutely contained and requires no other apparatus except a C.R.O. if one wants to observe waveforms at different points.
Practical experience on this board carries great educative value for Science and Engineering Students.
01. Multichannel Tuner.
02. Video IF Sub-System.
03. Sound Section.
04. Video amplifier and picture tube biasing.
05. Horizontal output sub-system.06. Horizontal output circuit.
07. Vertical deflection circuit.
08. Low voltage power supply.
01. 80 watt isolation transformer to avoid shock etc. while operating.
02. Board size 48" x 39", using white Bakelite sheet for better safety, rigidness & contrast.
03. Full block diagram of the receiver printed on the panel itself.
04. Divided into different sections for easy teaching.
05. The PCBs assembled are fixed on individual chassis by means of spring guarded clamps. These individual stages are eas
removable, just by pulling out the connectors and springs within no time.06. Volume control, Brightness control, Contrast and Vertical hold are mounted on the main board with knobs on the front. A.G.
Horizontal hold, Height and Vertical Linearity are present in the form of preset on respective PCBs. These can be varied and effeof variation can be studied.
07. Test points are provided for experiments. Miniature sockets of Red Colour indicate H.T. & L.T. voltage points. Black sockets ground connections provided wherever necessary. A to K correspond to Video input, Sync, Output, Oscillator linearity, Horizonreference and output pulses etc., and are provided by miniature sockets of different colours on the main board, connections begiven from individual PCBs. Wave shapes at these test points are clearly given on the main schematic in the same order, so that atrainee can compare the wave shape with one on the oscilloscope.
08. 51 cm (B & W) Picture tube.
09. Loud speaker size 6" x 4".
10. A frame of tabular construction sturdy enough to support the board and picture tube.
11. Adequate no. of other Electronic Components.
12. Mains ON/OFF switch, Fuse and neon indicator.* The unit is operative on 230V 10% at 50Hz A.C. Mains.
* Good Quality, reliable terminal/sockets are provided at appropriate places on panel for connections/observation of waveforms.
* Strongly supported by detailed Operating Instructions, giving details of Object, Theory, Design procedures, Report Suggestions Book References.
