Understanding Analog Signature Analysis with the Huntron Tracker 2800S
The Tracker 2800S uses Analog Signature Analysis when testing PCB Boards. Firstly, it features variable range parameters resulting in over 100 combinations of voltage, source resistance and frequency. The 2800S is a great off-line support tool for the automated Huntron Access Prober diagnostic systems.
The Tracker works by applying a current-limited AC signal across two points of a component. The current flow causes a vertical signature deflection, while the applied voltage causes a horizontal deflection. Together they form a unique V/I signature that represents the overall health of the device under test. Analysing the signature can quickly determine whether the component is good, bad, or marginal.
Cable based Scanning
The Tracker 2800S features two 40 pin IDC connectors (one per channel) where custom cable interfaces can be used to quickly scan PCB connectors as a type of “first pass” test. If signature differences are detected then you can trace the connector pin to the component level saving you troubleshooting time.
You can also use IC clips and cables to easily scan standard ICs and select SOICs. Clip and cables are readily available from companies such as Digi Key.
