ABSTRACT:
A pattern or test signal generating system and method is disclosed that is particularly well suited for servicing of T.V. receivers and the like. The system provides a series of individually selectable outputs that are utilized to produce patterns on the image-producing device of a unit to be serviced, including a COLOR QUAD pattern, a GRAY QUAD pattern, and a HATCHDOTS pattern. The system is lightweight and portable yet provides the plurality of outputs which enhance out-of-shop servicing of T.V. receivers. By the addition of the QUAD and HATCHDOTS patterns, the capability and versatility of the system is increased particularly for testing and adjusting color television receivers, closed-circuit monitors and the like. A system modification is also disclosed for providing an NTSC type color bar pattern.
