The 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 minimise the learning curve to help engineers and scientists learn faster, work smarter, and invent easier.

With its 10 A/1000 W pulse current and 7 A/100 W DC current capability combined with dual 18-bit 1MS/s digitisers, the 2461 is optimised for characterising and testing high power materials, devices, and modules, such as silicon carbide (SiC), gallium nitride (GaN), DCDC 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 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.

To help users who wish to transition to the 2461 from Keithley’s legacy 2420, 2425, 2430, and 2440 SMUs, the 2461 now includes four SCPI emulation modes for each of the older models, minimising SCPI code rewriting and maximising your investment.
