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

minimize 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

digitizers, the 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 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, minimizing SCPI code rewriting and

maximizing your investment.

Key Features

• One tightly coupled instrument that combines the

capabilities of analyzers, curve tracers, and I-V

systems at a fraction of their cost

• Wide coverage up to 105 V/7 A DC 100 W, 100 V/10 A

Pulse 1000 W max.

• Dual 1 MS/s digitizers for fast sampling measurements

• Five-inch, high resolution capacitive touchscreen GUI

• 0.012% DCV accuracy with 6½-digit resolution

• Source and sink (4-quadrant) operation

• Four “Quickset” modes for fast setup and

measurements

• Context-sensitive help function

• Front panel input banana jacks; rear panel mass

termination screw connections

• SCPI and Test Script Processor (TSP®)

programming modes

• Front-panel USB 2.0 memory I/O port for transferring

data, test scripts, or test configurations

The 2461’s home screen makes testing intuitive and helps minimize the

learning curve for new users.
