SourceMeter ® SMU Instrument
The Model 2450 is Keithley’s next-generation SourceMeter source measure
unit (SMU) Instrument that truly brings Ohm’s law (current, voltage, and
resistance) testing right to your fingertips. Its innovative graphical user
interface (GUI) and advanced, capacitive touchscreen technology allow
intuitive usage and minimize the learning curve to enable engineers and
scientists to learn faster, work smarter, and invent easier. The 2450 is the
SMU for everyone: a versatile instrument, particularly well-suited for characterizing modern scaled semiconductors, nano-scale devices and materials, organic semiconductors, printed electronics, and other small-geometry
and low-power devices. All this combined with Keithley SMU precision and
accuracy allow users to Touch, Test, InventTM with the new favorite go-to
instrument in the lab for years to come.
Learn Faster, Work Smarter, Invent Easier
Unlike conventional instruments with dedicated pushbutton technology and small, obscure, limited-character displays, the 2450 features a five-inch, full-color, high resolution touchscreen that facilitates ease of use, learning, and optimizes overall speed and productivity. A simple icon-based menu
structure reduces configuration steps by as much as 50 percent and eliminates the cumbersome
multi-layer menu structures typically used on soft-key instruments. Built-in, context-sensitive help
enables intuitive operation and minimizes the need to review a separate manual. These capabilities
combined with its application versatility make the 2450 the SMU instrument inherently easy to
use for basic and advanced measurement applications, regardless of your experience level with
SMU instruments.

Ease of Use Beyond the Touchscreen
In addition to its five-inch, color touchscreen, the 2450 front panel has many features that
supplement its speed, user-friendliness, and learnability, including a USB 2.0 memory I/O port, a
HELP key, a rotary navigation/control knob, a front/rear input selector button, and banana jacks for
basic bench applications. The USB 2.0 memory port supports easy data storing, saving instrument
configurations, loading test scripts, and system upgrades. Plus, all front panel buttons are backlit to
enhance visibility in low-light environments.

Model 2450 front panel with high resolution, capacitive touchscreen.
Four “Quickset” modes simplify user setup. With one touch, the instrument can be quickly configured
for various operating modes without the need to configure the instrument indirectly for this operation.
Comprehensive Built-in Connectivity
Rear panel access to rear-input triax connectors,
remote control interfaces (GPIB, USB 2.0, and
LXI/Ethernet), D-sub 9-pin digital I/O port (for
internal/external trigger signals and handler
control), instrument interlock control, and
TSP-Link® jacks enables easy configuration
of multiple instrument test solutions and
eliminates the need to invest in additional
adapter accessories.

TriggerFlow™ Building Blocks for
Instrument Control and Execution
The 2450 incorporates Keithley’s new TriggerFlow triggering
system that allows user control of instrument execution. Similar to
developing a flow chart, TriggerFlow diagrams are created using
four fundamental building blocks:
• Wait – Waits for an event to occur before the flow continues
• Branch – Branches when a condition has been satisfied
• Action – Initiates an action in the instrument, for example,
measure, source, delay, set digital I/O, etc.
• Notify – Notifies other equipment that an event has occurred
