The DG2040 Data Generator is a portable digital data generator designed for high performance and ease of use. The DG2040 Data Generator is easy to use for testing and evaluating semiconductors and logic circuits, which are continually becoming faster and more complex. The DG2040 Data Generator provides high performance and a wide range of functions in a compact package. Following are the main features of the DG2040 Data Generator : Maximum data rate of 1.1 GHz 256 K word pattern memory Flexible sequence looping (which does the equivalent of over a billion word patterns) Two channels (Complementary) For each output channel: Variable output levels (from –1.125 to +3.5 V, into 50 W) Edge Control function (CH0 only) Delay setting (–1.0 ns to +2.0 ns, 10 ps resolution) Serial/Parallel pattern editing Any memory size from 360 words to 256 K words can be used easily with no restrictions within that range. Either of the two bit data channels can be assigned to any output channel. The output channels support setting of high and low output voltage levels, and delay time. CH0 supports edge position. The DG2040 Data Generator also provides a 4000-step sequence controller, which enables the generation of not only a data pattern longer than the pattern memory but also dynamic pattern change triggered by external events. The DG2040 Data Generator provides flexible data editing functions, including word and line unit input and extended data creation functions. The DG2040 Data Generator also provides functions that are required for system construction, such as a sequencing function which is a jump function using external input.
