Abstract: A unified software apparatus and method for evaluating a generic electrical signal and complex multiple-format video signals. The methods may be operated manually or programmatically and are especially intended for evaluating analog signals within an automated testing environment. The test signal data is supplied by an external source such as an external hardware digitizer or other means. This signal data may be analog or digital in nature and may comprise up to three separate channels. The apparatus generates visual aids and supporting numerical computations, resulting in concrete and tangible results, allowing analysis based upon user selected criteria such as voltage measurements, histograms, frequency domain computations, or total harmonic distortion. In addition to these methods, video waveforms may be analyzed for content based upon numerical measurements applied to a region-within-a-region concept.

Abstract: The display simulator analyzer is a fully integrated processor controlled instrument used for testing video display devices. The test signals may be generated by a video function generator, a high resolution graphics generator, a modulator or combinations thereof. As the name implies, the simulator-analyzer also measures and analyzes parameters generated from an euipment under test by means of its analyzer, which has incorporated therein a counter-timer, a real time digitizer and a sync stripper.
