The high power Model 2651A is the newest addition to the Series 2600A family of System SourceMeter
instruments. Specifically designed to characterize and test high power electronics, these source measurement unit (SMU) instruments can help you improve productivity in applications across the R&D,
reliability, and production spectrums, including high brightness LEDs, power semiconductors, DC-DC
converters, batteries, and other high power materials, components, modules, and subassemblies.
The Model 2651A, like every Series 2600A SourceMeter instrument, offers a highly flexible, fourquadrant voltage and current source/load coupled with precision voltage and current meters. It can
be used as a:

Two Measurement Modes: Digitizing or Integrating
Precisely characterize transient and steady-state behavior, including rapidly changing thermal effects,
with the two measurement modes in the Model 2651A. Each mode is defined by its independent
analog-to-digital (A/D) converters.
The Digitizing Measurement mode enables 1µs per point measurements. Its 18-bit A/D converters allow you to precisely measure transient characteristics. For more accurate measurements,
use its Integrating Measurement mode, which is based on 22-bit A/D converters. The Integrating
Measurement mode is provided in all Series 2600A instruments.

Expansion Capabilities
Through TSP-Link® technology, multiple Model
2651As and other Series 2600A instruments can
be combined to form a larger integrated system
with up to 64 channels. Precision timing and
tight channel synchronization are guaranteed
with built-in 500ns trigger controllers. True
SMU instrument-per-pin testing is assured with
the fully isolated, independent channels of the
SourceMeter instruments.

Keithley’s TSP and TSP-Link technology
enables true SMU-per-pin testing without
the power and/or channel limitations of a
mainframe-based system.
Two A/D converters are used with each
measurement mode (one for current and the
other for voltage), which run simultaneously
for accurate source readback that does not
sacrifice test throughput.

Also, when two Model 2651As are connected in
parallel with TSP-Link technology, the current
range is expanded from 50A to 100A. When two
units are connected in series, the voltage range
is expanded from 40V to 80V. Built-in intelligence simplifies testing by enabling the units
to be addressed as a single instrument, thus
creating an industry-best dynamic range (100A
to 1pA). This capability enables you to test a
much wider range of power semiconductors and
other devices.

Standard Capabilities of
Series 2600A Instruments
Each Model 2651A includes all the features and
capabilities provided in the other Series 2600A
instruments, such as:
• Ability to be used as either a bench-top
I-V characterization tool or as a building
block component of multiple-channel I-V
test systems
• TSP Express software to quickly and
easily perform common I-V tests without
programming or installing software
• ACS Basic Edition software for semiconductor
component characterization (optional).
ACS Basic now features a Trace mode for
generating a suite of characteristic curves.
• Keithley’s Test Script Processor (TSP®), which
enables creation of custom user test scripts to
further automate testing, and also supports
the creation of programming sequences
that allow the instrument to operate
asynchronously without direct PC control.
• Parallel test execution and precision timing
when multiple Series 2600A instruments are
connected together in a system
• LXI Class C compliance
• 14 digital I/O lines for direct interaction with
probe stations, component handlers, or other
automation tools
• USB port for extra data and test program
storage via USB memory device

Node 2
SMU INSTRUMENTS
+5VDC
(on DIGITAL I/O
connector)
KEYPAD OPERATIONS:
• Change host interface settings
• Save and restore instrument setups
• Load and run factory and user defined test scripts that prompt for input and send results to
the display
• Store measurements into dedicated reading buffers
PROGRAMMING: Embedded Test Script Processor (TSP®) scripting engine is accessible from any
host interface.
• Responds to individual instrument control commands.
• Responds to high speed test scripts comprised of instrument control commands and Test
Script Language (TSL) statements (for example, branching, looping, and math).
• Able to execute high speed test scripts stored in memory without host intervention.
MINIMUM USER MEMORY AVAILABLE: 16MB (approximately 250,000 lines of TSP code).
TEST SCRIPT BUILDER: Integrated development environment for building, running, and
managing TSP scripts. Includes an instrument console for communicating with any TSP enabled
instrument in an interactive manner. Requires:
• VISA (NI-VISA included on CD)
• Microsoft® .NET Framework (included on CD)
• Keithley I/O Layer (included on CD)
• Intel® Pentium III 800MHz or faster personal computer
• Microsoft Windows® 2000, XP, Vista®, or 7
TSP EXPRESS (embedded): Tool that allows users to quickly and easily perform common I-V tests
without programming or installing software. To run TSP Express, you need:
• Java™ Platform, Standard Edition 6
• Microsoft Internet Explorer®, Mozilla® Firefox®, or another Java-compatible web browser
SOFTWARE INTERFACE: TSP Express (embedded), direct GPIB/VISA, read/write with Microsoft
Visual Basic®, Visual C/C++®, Visual C#®, LabVIEW™, CEC TestPoint™ Data Acquisition
Software Package, NI LabWindows™/CVI, etc.
READING BUFFERS: Nonvolatile memory uses dedicated storage areas reserved for measurement
data. Reading buffers are arrays of measurement elements. Each element can hold the
following items:
• Source setting (at the time the measurement was taken)
• Measurement
• Range information
• Measurement status
• Timestamp
Two reading buffers are reserved for each Model 2651A channel. Reading buffers can be filled
using the front panel STORE key and retrieved using the RECALL key or host interface.
Buffer Size, with timestamp and source setting: >60,000 samples.
Buffer Size, without timestamp and source setting: >140,000 samples.
SYSTEM EXPANSION: The TSP-Link expansion interface allows TSP-enabled instruments to
trigger and communicate with each other. See figure below.
To Additional Nodes
Each Model 2651A has two TSP-Link connectors to make it easier to connect instruments
together in sequence.
• Once source-measure instruments are interconnected through the TSP-Link expansion
interface, a computer can access all of the resources of each source-measure instrument
through the host interface of any Model 2651A
• A maximum of 32 TSP-Link nodes can be interconnected. Each source-measure instrument
consumes one TSP-Link node.
TIMER: Free-running 47-bit counter with 1MHz clock input. Resets each time instrument power is
turned on. If the instrument is not turned off, the timer is reset to zero every 4 years.
Timestamp: TIMER value is automatically saved when each measurement is triggered.
Resolution: 1µs.
Timestamp Accuracy: ±100ppm.
