The Tektronix DG2020 Digital Pattern Generator creates complex digital patterns and sequences for functional testing, debugging, and characterization of digital designs. This instrument generates programmable test signals across multiple output channels with precise timing control, supporting data rates to 200 Mbits/s and pattern depths of 64 K words per channel. Engineers use it for circuit board and component verification, with flexible sequence control including jump, event, and nested loops. The generator integrates into ATE systems via GPIB and RS-232-C interfaces and accepts pattern data through floppy drive import or DG-link software utility in CSV format.
