The DG2020A is a digital data generator designed for high performance and ease of use. The DG2020A is easy to use for testing and evaluating semiconductors and logic circuits, which are continually becoming faster and more complex. The DG2020A provides, in a compact package, high performance and a wide range of functions. Features include a maximum data rate of 200 MHz, a 64K word pattern memory, 12 channels (with support for up to 36 channels by adding optional modules), a 100 ps timing skew adjustment function, and variable output levels (from --3 to +7V). Any memory size from 64 words to 64K words can be used easily, with no restrictions within that range. TTL output level and variable output level pods can be selected as the data output pods. Both pod types support setting of their output stages to a high-impedance state. Each module supports delays in 4 of its 12 channels with a 100-ps-resolution variable delay time. The DG2020A provides flexible data editing functions, including word and line unit input and extended data creation functions. Furthermore, the DG2020A provides a rich set of functions required for system construction, such as a sequencing function, a jump function using external input, and an inhibit function. Features The DG2020A supports smooth and rapid product development by simulating the digital signals from incomplete sections of a product. Logic function test systems can be constructed by combining this instrument with a logic analyzer. Margin tests can be easily performed by using this instrument to generate patterns that have a low probability of occurrence or are difficult to generate. This can increase end-product reliability. Interactive digital simulation systems can be constructed using the sequence output, external jump, and tristate control functions. Flexible data output functions make the DG2020A an ideal data generator for simulation of LCD display units, CCD line and area sensors, and all types of digital circuits.
