The Agilent/HP 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.
Qualified signature Fault isolation in complex
products can be done by windowing the signature collection to
specific modules or devices. The setup can be done quickly with no
major test changes. HP-IB All measurement and control functions are
fully programmable. Composite signature Composite
signatures are computed for any grouping of digital signals. If the
composite compares correctly to the reference signal, all of the
signatures are correct, and do not have to be compared
individually.
Signature memory Signatures are stored in memory
after the probe switch is pushed. The memory stores the last 32
readings. Signatures can be compared in groups, not after every
probe, by reviewing memory in the RECALL mode.
