Keithley 2461 High Current SourceMeter

For newer applications, Keithley recommends the 2450, 2460 and the 2470 SMU.

The Model 2461 High Current SourceMeter® Source Measure Unit (SMU) Instrument brings advanced Touch, Test, Invent® technology right to your fingertips. It combines an innovative graphical user interface (GUI) with capacitive touchscreen technology to make testing intuitive and minimize the learning curve to help engineers and scientists learn faster, work smarter, and invent easier.

With its 10A/1000W pulse current and 7A/100W DC current capability combined with dual 18-bit 1MS/s digitizers, the Model 2461 is optimized for characterizing and testing high power materials, devices, and modules, such as silicon carbide (SiC), gallium nitride (GaN), DC-DC converters, circuit protection devices, solar cells and panels, high brightness LEDs and lighting systems, electrochemical cells and batteries, and much more.

These new capabilities, combined with Keithley’s expertise in high precision, high accuracy SMU instruments, will make the Model 2461 a “go-to instrument” for high current sourcing and high speed measurement applications in the lab and in the rack for years to come.
