blog O Tektronix Launches 2460 Highcurrent SMU for Faster RD

Engineers working with high-power semiconductor devices now have access to a revolutionary testing solution that combines multiple functionalities into a single intuitive instrument. The Tektronix 2460 High-Current Source Measure Unit (SMU) integrates advanced Touch, Test, Invent® technology with a capacitive touchscreen interface, redefining efficiency in power electronics characterization.

Touchscreen Revolution in High-Current Testing

The 2460 SMU delivers unprecedented control over high-current testing capabilities, supporting up to 7A DC and pulsed current measurements through its intuitive five-inch touchscreen interface. Designed specifically for characterizing wide-bandgap semiconductors like silicon carbide (SiC) and gallium nitride (GaN), as well as power modules, DC-DC converters, power MOSFETs, solar cells, LED lighting systems, and electrochemical cells, this instrument represents a significant leap forward in test equipment usability.

Key Advantages at a Glance

• Integrated Design: Combines analyzer, curve tracer, and I-V system capabilities in one cost-effective solution
• Expanded Test Range: Supports up to 105V voltage and 7A DC/pulsed current with 100W maximum power
• Intuitive Touchscreen GUI: High-resolution capacitive display significantly reduces learning curve
• Measurement Precision: Delivers 0.012% basic measurement accuracy with 6½-digit resolution
• Four-Quadrant Operation: Supports both source and sink modes for flexible test configurations
• Quick Setup Modes: Four preset configurations enable rapid instrument setup
• Context-Sensitive Help: Built-in guidance system reduces manual consultation

Enhanced Usability and Workflow Optimization

The 2460's touchscreen interface reduces test configuration steps by up to 50% compared to traditional soft-key instruments. Its icon-based menu structure and context-sensitive help system create a more natural interaction experience for both novice users and experienced engineers. Front panel features include USB 2.0 memory I/O ports, backlit buttons, and banana jacks for benchtop applications.

Technical Specifications Overview

Advanced System Integration Capabilities

The 2460 incorporates Keithley's TriggerFlow® system for precise instrument control, allowing users to create complex trigger models through a logical flowchart interface. When integrated into multi-channel test systems, its embedded Test Script Processor (TSP®) enables independent script execution and channel expansion without a mainframe chassis.

For engineers developing custom applications, the instrument supports SCPI and TSP programming modes, along with available LabVIEW®, IVI-C, and IVI-COM drivers. The included KickStart software enables rapid measurement setup without programming requirements.
