Source Measure Unit Addresses High-Power Device Measurement Applications

Tektronix Inc. has introduced an easy-to-use, graphical-based source measure unit (SMU) instrument for optimizing and characterizing high power materials, devices and modules.

The Keithley 2461 High Current SourceMeter SMU Instrument offers advanced capabilities for creating precisely-controlled 10 amp/100 volt, 1000 watt high-current pulses that minimize power device thermal effects and maintain device integrity. Its dual 18-bit high speed digitizers facilitate measuring actual device operation that can be graphically displayed right on the front panel for immediate analysis. Based on the successful 2450 and 2460 SMU platforms, the 2461 features the highest levels of dc and pulse source and sink performance in its class, enabling users to gain deeper insight into their designs.

Researchers, scientists and design engineers developing next generation high-power materials and devices need the ability to make measurements at a variety of dc and pulse power levels for verifying device performance, while at the same time minimizing the effects of device self-heating that often result in device or module failures. This applies to such segments as materials research, semiconductor devices, circuit protection devices, advanced lighting technologies, energy storage and generation components, and power management electronics used in consumer electronics.

Like the other Keithley graphical SMUs from Tektronix, the 2461 incorporates the simple and intuitive Touch, Test, Invent user experience that minimizes the learning curve and accelerates test setup for faster time to answer. The graphical touchscreen interface allows users to interact with results right on the front panel using natural gestures similar to a smartphone or tablet and to quickly zoom in and out of data while conducting detailed analysis. A built-in open source scripting language enables users to create libraries of reusable, customizable test software for specialized measurement applications.
