The Keithley 2461 High Current SourceMeter® is a next-generation SMU (Source Measure Unit) designed for high-current and fast transient testing. With the ability to source up to 105 V, 7 A DC, or 10 A pulse (100 W max), the 2461 provides the power and accuracy required for modern power semiconductor devices and energy components.
Equipped with an integrated digitizer, the 2461 enables high-speed current and voltage waveform capture, making it ideal for analyzing transient behavior in devices such as MOSFETs, IGBTs, LEDs, solar cells, and batteries. Its intuitive Touch, Test, Invent® (TTI) graphical touchscreen interface streamlines test setup and operation, while scripting and automation support enhance productivity in both R&D and production environments.
