16913A Colour pattern Generator is designed for educational and service use. 14 Test patterns normally required for monochrome & colour TV installations can be easily selected.

16913A generates patterns and multicolour bars. Patterns provide video and RF modulated signals for alignment. Colour bars are used for colour settings. Horizontal line, vertical line & circle patterns are used for Raster, Geometrically and Linearly adjustments. White pattern is used for white balancing. 16913A provides fixed composite video signals which helps the students for easy analysis.
