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 6^-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 configuration

Learn Faster, Work Smarter, Capture Real Device Operation withInvent Easier the Built-in Dual 1 MS/sec Digitizers The 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, context-sensitive help supports intuitive operation...

The 2461, built on the fourth generation of the awardwinning SourceMeter SMU platform, leverages the proven capabilities of previously introduced high current SMU instruments from Keithley, including the 2420, 2425, and 2440. It offers a highly flexible, four-quadrant voltage and current source/load coupled with precision voltage and current measurements. This all-in-one instrument gives you the capabilies of a: • Precision power supply with V and I readback • True current source • Digital multimeter (DCV, DCI, ohms, and power with 6'/2-digit resolution) • Precision electronic load • Pulse generator...

Mass screw terminal connections 2461 rear panel connections are optimized to maintain signal integrity and speed system setup. Four “Quickset” modes simplify instrument 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 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...

Typical Applications Ideal for current/voltage (I-V) characterization and functional test of a wide range of today's modern electronics and devices, including: • Power semiconductors and materials - IGBTs, Power MOSFETs, HBLEDs • Power management and protection devices - Telecom power management chipsets - DC-DC converters - Metal-oxide varistors (MOV), transient voltage suppressors (TVS) - Galvanic cycling - Cyclic voltammetry

TriggerFlow ® Building Blocks for Instrument Control and Execution The 2461 incorporates Keithley’s TriggerFlow triggering system, which provides user control over instrument execution. TriggerFlow diagrams are created in much the same way that flow charts are developed, using four fundamental building block types:: Contact Check Function The Contact Check function makes it simple to verify good connections quickly and easily before an automated test sequence begins. This eliminates measurement errors and false failures associated with contact fatigue, breakage, contamination, loose or broken...

KickStart start-up software lets users be ready to make measurements in minutes. Instrument Control Start-up Software KickStart instrument control/start-up software enables users to start making measurements in minutes without programming. In most cases, users merely need to make some quick measurements, graph the data, and store the data to disk for later analysis in software environments such as Excel. KickStart offers: • Configure and control up to four SMU instruments for DC or Pulsed I-V test in either the same app, same project, or a combination of the two. • Create tests by mixing any...

Curve tracing analysis is a critical task for many users in the semiconductor development supply chain. Engineers and technicians both hold the traditional curve tracer as the simplest, fastest method for generating characteristic I-V curves on a device. They are heavily used by engineers in failure analysis and incoming inspection to qualify parts, identify counterfeit devices, and to quickly identify the location of a failure on damaged devices. SMUs have typically been limited to predefined sweeps with longer set up times than curve tracers — until I-V Tracer. Keithley's I-V Tracer app leverages...
