The Keithley 2450 200V/1A/20W Advanced Touchscreen SourceMeter SMU Instrument 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.

Fourth-Generation, All-in-One SMU Instrument

The 2450 is the fourth-generation member of Keithley's award-winning SourceMeter family of SMU instruments; it offers a highly flexible, four-quadrant voltage and current source/load coupled with precision voltage and current meters. This all-inone instrument can be used as a:

Precision power supply with V and I readback

True current source

Digital multimeter (DCV, DCI, ohms, and power with 6 1/2-digit resolution).

Precision electronic load

Trigger controller

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.

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.

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

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.

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 an 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.

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.

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
