The Model 2461 High Current

SourceMeter

Source Measure Unit

(SMU) Instrument brings advanced

Touch, Test, Invent

technology right to

your fingertips. It combines an innova-

tive 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 capa-

bility 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, electro-

chemical 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 measure-

ment applications in the lab and in the rack for years to come.

Learn Faster; Work Smarter; Invent Easier

The Model 2461 features a five-inch, full-color, high resolution touchscreen that

supports intuitive operation, helps operators become familiar with the instrument

quickly, and optimizes overall speed and productivity. A simple icon-based menu

structure reduces the

number of steps required

to configure a test by as

much as 50 percent and

eliminates the cumbersome

multi-layer menu structures

typically used on soft-key

instruments. Built-in, con-

text-sensitive help supports

intuitive operation and min-

imizes the need to review

a separate manual. These

capabilities, combined with

the Model 2461’s high ver-

satility, simplify its operation

in both basic and advanced

measurement applications,

regardless of the user’s pre-

vious experience in working

with SMU instruments.

The Model 2461’s home screen makes testing intuitive and

helps minimize the learning curve for new users.

The graphical SMU’s icon-based menu structure helps even

novice users configure tests quickly and confidently.

Capture Real Device Operation with the Built-in Dual 1MS/sec Digitizers

Capturing and displaying real device operation, waveforms, and transient events just

got easier with the Model 2461’s digitizing function. The two built-in 1MS/sec, 18-bit

digitizers make it possible to acquire both voltage and current waveforms simultane-

ously without the need to use a separate instrument. The digitizing functions employ

the same DC voltage and current measure ranges that the standard A/D converter

uses. In addition, the voltage digitizing function uses the same DC voltage 10GΩ

input impedance levels to reduce loading significantly on the device under test (DUT).

The high speed digitizing function allows capturing and displaying voltage and current measure-

ments simultaneously.

All-in-One SMU Instrument

The Model 2461, part of Keithley’s fourth generation of SourceMeter SMUs, leverag-

es the proven capabilities of the original Series 2400 SourceMeter SMU Instruments,

such as the Models 2420, 2425, 2430, and 2440. SMU instruments offer a highly

flexible, four-quadrant voltage and current source/load coupled with precision volt-

age and current measurements. This all-in-one instrument offers the capabilities of a:

• Precision power supply with V and I readback

• True current source

• Digital multimeter (DCV, DCI, ohms, and power with 6½-digit resolution)

• Precision electronic load

• Pulse generator

• Trigger controller
