  • Features Huntron SigAssist™ for display of signature resistance, capacitance and breakdown voltage
  • Test gate-fired devices with a built-in DC voltage source
  • High resolution color LCD for signature and menu display
  • Individually select source voltage, source resistance and test frequency to create over 100 range combinations

Huntron's next generation troubleshooting tool
with multi-pin scanning capabilities

The HuntronŽ TrackerŽ 2700S extends the capabilities of the popular Tracker 2700 to scan and compare up to 40 pins per channel using standard IC clips and cables. Comparison can take place manually or automatically allowing you to pick out the signatures differences quickly. Its low voltage ranges also make it ideal for testing passive devices such as high value capacitors while still in-circuit.

The Huntron Tracker 2700S is an ideal addition to the service engineer's bench or as a compliment to a Huntron ProTrack I system. Using a power-off test method known as Tracker Signature Analysis, it eliminates the risk of further circuit damage, which often occurs when power is applied.

Troubleshooting Challenges

Modern complex switching power supplies with fail-safe protection circuits contain many passive components that are difficult to test in circuit due to parallel solid state devices. The 200mV range of the Tracker 2700S allows resistors, capacitors and inductors to be analyzed without turning on the parallel solid state devices. The passive devices are essentially tested "out of circuit".

Today's portable electronic devices use 3 volt or lower logic circuits. The low test voltage ranges of the Tracker 2700S make it an ideal tool to troubleshoot these products.

The Tracker 2700S features variable ranges parameters resulting in over 100 combinations of voltage, source resistance and test frequency.

Tracker Signature Analysis

The Tracker works by applying a current-limited AC signal across two points of a component. The current flow causes a vertical deflection of the CRT trace, 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. Analyzing the signature can quickly determine whether the component is good, bad, or marginal.
