The objective of this project was to construct a Composite Video Pattern Generator, which can be used as a teaching tool in the video field as well as a laboratory instrument, useful for repairing and adjusting television receptors. This instrument is in no way intended to be a commercial set, because I cannot guarantee all the specifications that a professional tool must have. However, the result is a high quality video equipment.
Patterns: Color Bars, Raster, Cross-hatch, Points Controls: independent R, G, B, luminance, chrominance and color burst Video output: composite video, 1 Vp-p at 75 ohms load Color system: PAL-N (option PAL-B/G/I, changing chroma oscillator crystal) Scanning system: Interlaced (Bars and Raster), Non-Interlaced (Cross-hatch and Points) Power supply: 12 Vdc (8 x AA alkaline batteries) Power consumption: 70 mA maximum (White Raster) Applications: television receptors adjustment (purity, convergence, linearity,|
