The Keysight 5006A high-accuracy signature analyzer troubleshoots digital circuits for applications in production test and repair, depot repair, or field service. The analyzer finds faults by tracing signal flow and measuring signatures (16-bit cyclic redundancy codes generated for blocks of data) that are compared to printouts or computer-stored signatures. Errors are quickly detected by comparing signatures, not entire bit streams. The 5006A employs patented signature analysis technique to generate a compressed, four-digit signature of a digital data stream at a logic node. Any fault associated with a device connected to the node will force a change in the data stream, and produce an erroneous signature. Simply probe the circuit, read the display, and compare to the known-good signature. Reference signatures can be generated by probing an operational circuit, or by external stimulation.
