B/W TV Demonstrator



* B/W TV Trainer: 14” monitor.

* B/W pattern Generator

 The trainer helps to studies :

  1. Different sections of a black and white TV receiver.
  2. Measurement of vertical sync., Horizontal sink, Horizontal Oscillator, Vertical blanking and Scanning frequency;
  3. Measurement of picture to sink ratio ( P / S ratio ).
  4. Identify faulty sections by simulating faults through SPDT switches.

Microtech Industries make Black & White TV Receiver Demonstrator Kit is a comprehensive trainer.  Provision for measurements of all important test points viz, Composite video signal, IF signal, Sound detector, Sound driver, Sound amplifier output, vertical sync, Horizontal sync, AFC, horizontal oscillator, Horizontal driver, Video output and Horizontal Blanking pulse in this trainer.  All these circuits are mounted on a single PCB. Hence all wiring mistakes are totally eliminated. Therefore the performance will be greatly enhanced. However performance of our TV Trainer may vary in operation compared to commercial TV Receivers.
