Tektronix 172

The Tektronix 172 is a programmable test fixture that automates sequential characterization of semiconductor devices in conjunction with the Tektronix 576 Curve Tracer. It executes up to eleven pre-programmed tests without manual intervention, eliminating repetitive setup changes and standardizing measurement conditions across device batches. The fixture programmably controls test parameters, voltage and current drive ranges, and deflection factor overrides on the 576, enabling precise characterization of JFETs, transistors, and diodes.
