The Tektronix 371A Curve Tracer is a programmable DC parametric characterization instrument engineered for detailed electrical analysis of power semiconductor devices. It delivers high-voltage and high-current pulsed testing capabilities across a broad dynamic range, supporting applications from device characterization to failure analysis in manufacturing and laboratory environments.
Technical Specifications
• Voltage Range: Up to 3,000 V (high voltage collector mode for Off-characteristics testing)
• Current Range: Up to 400 A peak pulsed; resolution down to 1 pA; programmable steps from 1 µA to 2 A
• Power Range: Up to 3,000 W
• Display: Digital storage with 100 points per division resolution and on-screen value readout
– Key Features
• Pulsed Measurement Mode: Low-duty-cycle pulse generation constructs device families without thermal stress, enabling full power curve visualization up to 3 kW or 300 W operation
• Cursor Analysis Tools: Dot cursors for direct voltage/current/gain readout; window cursors for small-signal measurements and go/no-go testing; function line cursors for slope and intercept determination
• Kelvin Sense Measurements: Four-wire voltage sensing eliminates lead resistance effects for measurement accuracy
• Waveform Processing: Envelope display, waveform comparison, and averaging modes reduce noise and enhance signal clarity
• Fully Programmable: GPIB control and front-panel operation support automated test sequences; 3.5-inch MS DOS-compatible disk storage preserves setups and data
– Typical Applications
Characterization of thyristors, SCRs, IGBTs, power MOSFETs, diodes, optoelectronic devices, and solar cells. Deployed in R&D, manufacturing quality control, incoming inspection, and failure analysis workflows.
– Compatibility & Integration
GPIB interface for remote automation. Non-volatile memory and disk-based configuration storage support repeatable measurement protocols across test campaigns.
