  1. Signature Analyser Function Review by Yolanda Kong and Russell Cayzer CNT 1A

  2. Signature Analyzer’s Process • Convert the lengthy serial data stream of a micro-processor based product into a four digit signature

  3. Signature Analyzer’s Purpose • Can function as a troubleshooter of microprocessor-based products • Each node produces a documented signature when a specific mode of operation is engaged • Matching codes are contained in the product service manual • The signature analyzer reads the node’s code and visually displays it • A miss-match points to a fault

  4. An Example of a Fault • The signature table states that the code at A2 should read HHCO ( to be found in the service manual) • If the Signature Analyzer’s display does not match the service manual’s code with the probe on A2 a fault exists

  5. Conclusion • The signature analyzer is a most useful fault locator • The operation is fast and a problem area can be determined with some basic troubleshooting concepts • This device incorporates a minimum amount of hardware alteration and no software changes at all
