Tektronix 571

Description

The 571 Curve Tracer is a semiconductor tester with a set of attractive specifications. It is a menu-driven, digital, microprocessor controlled instrument, designed to easily make DC measurements on several types of semiconductors.

The 571 has the capability of testing the following types of semiconductors:

• Bipolar Transistors NPN and PNP
• Diodes
• F.E.T.'s
• Thyristors and Triac's

Features:

• Easy to operate 
• Menu Driven
• Digital Waveform
• Non-Volatile EEROM- Store 12 Test Setups
• Accurate Cursor Measurements
• Hard Copy Output to Matrix Printer
• Built-in Safety Features
• Composite Video Output (50 Hz)
• Built-in Test Sockets

The C.R.T. is used for the presentation of the menu's and the test results. The 10 keys are used for selecting the desired function and paramaters from the menu.

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
