Tektronix 370 Curve Tracer
Description
The 370 is a high-performance, GPIB-programable digital-storage curve tracer that provides static and dynamic semiconductor device measurements. This versatile instrument stimulates, measures, and displays the semiconductor characteristics of a variety of two, three, and four-terminal devices/ including bipolar transistors, field effect transistors, silicon-controlled rectifiers, diodes, thyristors, optoisolators, wafers, integrated circuits, etc. A variety of measurements can be performed using either grounded-emitter or grounded-base configurations.
The collector supply produces ac, rectified ac, or dc voltages ranging from 0 to ±2000 volts. This high voltage, combined with a current sensitivity of 100 pA/div, permits extended breakdown measurements on a device under test. A step generator produces voltage or current steps of either polarity for application to the base or emitter terminal. The step generator may also be operated in a pulsed mode to reduce DUT power dissipation.
In addition to conventional curve tracer performance, the 370 includes the following features:
1. Digital storage capability that allows bright and stable display and useful cursor measurements. The 370 can store up to 16 families of characteristic curves in a bubble memory cassette, display them on the crt, and send them for data processing via the GPIB. The bubble memory also provieds non-volatile storage for up to 16 complete front-panel setups.
2. Tow extended aquisition modes, called Averaging and envelope. Averaging reduces display noise in high sensitivity ranges. Envelope mode displays the maximum and minimum vertical or horizontal excursion of each curve, which is useful for detecting long-term variations such as thermal drift.
3. GPIB command-controllable front-panel functions. Nearly all are remotely controllable. (Exceptions are those controls intended only for manual operation, such as INTESITY, FOCUS, COLLECTOR SUPPLY HIGH-LOW control, etc. Also, curve data can be sent to or received from an external controller through the GPIB.
4. The CENTRONICS-compatible plotter interface permits sending displayed curve data and digital on-screen readouts to a digital plotter without an external controller.
5. Other features include an auxiliary voltage supply, cursor measurement readout, and diagnostic routines.
Installation
Initial Inspection
This instrument was thoroughly inspected for mechanical and electrical defects before shipment. It should be free of mars or scratches and meet or exceed all electrical specifications. To confirm this, inspect the instrument for physical damage incurred in transit and test the electrical performance by following the First Time Operation instructions in Section 3, Operating Instructions. For a complete verification of instrument performance, refer a qualified service technician to the performance check section of the service manual. If a discrepancy is found, contact your local Tektronix Field Office or representative.
Power Source Information
This instrument operates from a power source having a neutral at or near ground (earth) potential. It is not intended for operation from two phases of a multi-phase system, nor across legs of a single-phase, three wire system. This instrument can be operated from either a 115-Volt or 230-Volt nominal supply source, 48 to 66 Hz. Table 1-1 is a listing of the line voltage ranges, line frequency range, and power consumption.
