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.
• Capabilities of analyzers,
curve tracers, and I-V systems
at a fraction of their cost.
• Five-inch, high resolution
capacitive touchscreen GUI
• 0.012% basic measure accuracy
with 6½-digit resolution
• Enhanced sensitivity with
new 20mV and 10nA source/
measure ranges
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.

Comparison of Model 2400 vs Model 2450.
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.

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.
Quickset modes enable fast setup and time
to measurements.

Convert Raw Data to Information
The 2450 provides a full plotting and sheet view to display sweeps,
measurement data, and charting right on the screen. It also supports
exporting to a spreadsheet for further analysis, dramatically improving
productivity for research, bench-top testing, device qualification,
and debugging.

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
Full data display, charting, and export to a spreadsheet lets you
convert raw data to useful information.

SourceMeter® SMU Instrument
Parallel Test Capability
With the TSP technology in the 2450, multiple devices can be
tested in parallel to meet the needs of device research, advanced
semiconductor lab applications, and even high throughput production test.
This parallel testing capability enables each instrument in the system to
run its own complete test sequence, creating a fully multi-threaded test
environment. The number of tests that can be run in parallel on a 2450
can be as high as the number of instruments in the system.
TriggerFlow building blocks let users create very simple to very
complex triggering models.
A TriggerFlow model using a combination of these building blocks can
be created from the front panel or by sending remote commands. With
the TriggerFlow system, users can build triggering models from very simple to complex with up to 255 block levels. The 2450 also includes basic
triggering functions, including immediate, timer, and manual triggering.
Unmatched System Integration and
Programming Flexibility
When the 2450 is integrated as part of a multi-channel I-V test
system, the Test Script Processor (TSP®) embedded scripting capability
allows test scripts to be run by the instrument, enabling the user to
create powerful measurement applications with significantly reduced
development times. TSP technology also offers channel expansion
without a mainframe. Keithley’s TSP-Link® channel expansion bus,
which uses a 100 Base T Ethernet cable, connects multiple 2450
instruments and other TSP instruments such as Keithley’s Series 2600B
SourceMeter SMU instruments and Series 3700A Switch/Multimeter
systems in a master-slave configuration that behaves as one integrated
system. The TSP-Link expansion bus supports up to 32 units per GPIB
or IP address, making it easy to scale a system to fit an application’s
particular requirements.
Free Instrument Control Start-up
Software and Web Interface
KickStart, Keithley’s new instrument control non-programming start-up
software, lets users start taking measurements in minutes. In most cases,
users merely need to make quick measurements, graph the data, and
store the data to disk to perform analysis in software environments
such as Excel.
KickStart offers the following functionality:
• Instrument configuration control to perform I-V characterization
• Native X-Y graphing, panning, and zooming
• Spreadsheet/tabular viewing of data
• Saving and exporting data for further analysis
• Saving of test setups
• Screenshot capturing of graph
• Annotation of tests
• Command line dialog for sending and receiving data
• HTML help
• GPIB, USB 2.0, Ethernet compliant
SMU INSTRUMENTS
The 2450 also includes a SCPI programming mode that optimizes the
instrument’s new features, as well as a SCPI 2400 mode that provides
backwards compatibility with the existing Model 2400 SourceMeter
instrument. Not only does this preserve your 2400 investment, but it
also eliminates re-work normally associated with upgrading to a new
instrument with new capabilities.
With KickStart start-up software, users are ready to take
measurements in minutes.
Simplified Programming
with Ready-to-Use Instrument Drivers
For users who want to create their own customized application software,
native National Instruments LabVIEW® drivers, IVI-C, and IVI-COM
drivers are available at www.keithley.com.
