Tektronix 571 Curve Tracer System - Semiconductor Testers

The 571 Curve Tracer is designed to accurately display the characteristics of two and three terminal semiconductor devices at a very affordable price. This easy-to-operate curve tracer is ideally suited for testing diodes, transistors, and thyristors.

Characteristic curves are digitized and displayed on a large video display CRT.

The 571 Curve Tracer is extremely versatile, yet remarkably easy to operate. Two main display screens are provided. The first screen is a menu page for selecting the device type and all relevant parameters. Parameters are selected and modified by a simple front-panel keypad entry.

The second screen displays the measured data- a family (set) of curves. The collector voltage and current parameters can be easily changed without switching back to the menu screen. An operator prompt line is provided at the bottom of each screen to always indicate which push-buttons are active.

Up to 12 parameter set-ups (12 completed tests) can be stored in non-volatile EEROM memory to speed up testing of frequently used devices.  One set of characteristic curves can be stored in RAM memory for comparison of one device to another (reference device). A monitor for classroom viewing can be connected to the monochrome video output.  A complete set of device adapter sockets are an integral part of the front-panel, preventing possible misplacement.
