Huntron Tracker 2000 I-V Curve Trace Pulse Generator

The Huntron Tracker 2000 I-V Curve Trace Pulse Generator is a power-off diagnostic instrument that captures and displays current-voltage signatures of electronic components installed on circuit boards. By applying a current-limited AC signal and comparing the resulting I-V curve against known good references, it identifies faulty devices - including those with subtle defects like leakage or substrate damage - without requiring complete circuit documentation. The integrated pulse generator enables dynamic testing of gate-fired devices such as SCRs, TRIACs, and optocouplers in active mode while the circuit remains unpowered.
