The Huntron Tracker 2800S is designed to complement conventional test instruments in the debug and troubleshooting process. Using the proven power-off test method known as Analog Signature Analysis it eliminates the risk of further circuit damage, which often occurs when power is applied. The Huntron Tracker 2800S is suited for today's varied signal circuit cards where Analog and Digital are mixed together. The Tracker 2800S 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.
