Abstract
A built-in test for dynamic raster video output is described for testing a plurality of analog video signals created from digital raster data, each of the analog signals having a plurality of analog signal components. In the apparatus, an addressing device is provided for selecting one of the analog signals to be tested, and a selector selects a desired analog signal component from the selected analog signal. An A/D converter then converts the selected signal component into a digital signal component, and a characteristic value is extracted therefrom. A memory is provided which stores predetermined characteristic value range data, and the extracted characteristic value is compared with the stored range data by a comparator to produce a result. A combination device then creates a combination of the result and an address of the selected analog signal component, and the combination is then stored for later retrieval.
