A Built-in Pattern Generator Gives You Digital Stimulus and Response in a Single Instrument

Selected 16800 Series models (16821A, 16822A and 16823A) also include a 48-channel pattern generator to drive down risk early in product development. With a pattern generator you can: • Substitute for missing boards, integrated circuits (ICs) or buses instead of waiting for missing pieces • Write software to create infrequently encountered test conditions and verify that the code works – before complete hardware is available • Generate patterns necessary to put a circuit in a desired state, operate the circuit at full speed or step the circuit through a series of states • Create a circuit initialization sequence Agilent 16800 Series portable logic analyzers with a pattern generator offer a variety of features that make it easier for you to create digital stimulus tests. Vectors up to 48 bits wide Vectors are defined as a “row” of labeled data values, with each data value from one to 48 bits wide. Each vector is output on the rising edge of the clock. Create stimulus patterns for the widest buses in your system. Depth up to 16 M vectors With the pattern generator, you can load and run up to 16 M vectors of stimulus. Depth on this scale is most useful when coupled with powerful stimulus generated by electronic design automation tools, such as SynaptiCAD’s
