Tektronix 371B High Power Curve Tracer
The Tektronix 371B Curve Tracer is an essential tool for engineers and technicians involved in the testing of power semiconductors. Renowned as an industry leader in high-power curve tracing, the Tektronix 371B excels in providing DC parametric characterization for a diverse range of power semiconductor devices, including thyristors, SCRs, IGBTs, and power MOSFETs.
Unmatched Testing Capabilities
With the capability to test off-characteristics at voltages up to 3,000 volts through its high-voltage collector mode, the 371B ensures thorough device evaluation. Additionally, the pulsed high-current collector mode delivers output current pulses exceeding 400 amps peak, allowing for in-depth on-characteristic testing. The unit supports high power testing of up to 3,000 watts, making it a versatile instrument for demanding applications.
Interactive Control and Customization
Users can interact with the Tektronix 371B via a comprehensive front panel or through a GPIB interface. This feature allows complete control over every operating parameter using a GPIB controller. For those seeking customized measurement solutions, Tektronix has made available a series of LabView drivers designed to facilitate innovative testing environments.
Advanced Data Management
The Tektronix 371B Curve Tracer is equipped to store up to 80 digitized characteristic curves on a diskette or in its internal non-volatile memory. This feature enables quick retrieval of previously stored data, facilitating temperature drift assessments and further evaluation of operating parameters. Each curve can be annotated with descriptive labels up to 24 characters in length.
Precision Measurement Features
Users will appreciate the three cursor measurement modes integrated into the Tektronix 371B:
- Dot Cursor: Provides instantaneous readouts of voltage, current, gm, or DC beta at any point on the display.
- Window Cursor: Allows positioning between two curves for small signal beta or gm measurements and aids in visual go/no-go tests.
- Function Line Cursor: Displays slope or intercept values for precise analysis.
Safety and Versatility
Included with the Tektronix 371B is a standard test fixture that provides a secure enclosure for devices under test, ensuring operator safety during measurements. This test fixture is compatible with standard adapters using Kelvin sensing, enhancing measurement accuracy.
