A Greater Measure of Conﬁdence

The Series 2600B System SourceMeter SMU Instruments are the industry’s leading current/voltage

source and measure solutions, and are built from Keithley’s third generation SMU technology. The

Series 2600B offers single- and dual-channel models that combine the capabilities of a precision

power supply, true current source, 6½-digit DMM, arbitrary waveform generator, pulse generator,

and electronic load – all into one tightly integrated instrument. The result is a powerful solution that

significantly boosts productivity in applications ranging from bench-top I-V characterization through

highly automated production test. For bench-top use, Series 2600B SMU instruments feature built-

in, Java-based software that enables plug & play I-V testing through any browser, on any computer,

from anywhere in the world. For automated system applications, the Series 2600B’s Test Script

Processor (TSP®) runs complete test programs from inside the instrument for industry-best through-

put. In larger, multi-channel applications, Keithley’s TSP-Link® Technology works together with TSP

Technology to enable high-speed, SMU-per-pin parallel testing. Because Series 2600B SourceMeter

SMU Instruments have fully isolated channels that do not require a mainframe, they can be easily

reconfigured and re-deployed as your test applications evolve.

Java-based Plug & Play I-V Test Software

The Series 2600B are the only SMU instruments to feature built-in, Java-based test software that

enables true plug & play I-V characterization through any browser, on any computer, from anywhere

in the world. This unique capability boosts productivity across a wide range of applications such as

R&D, education, QA/FA, and more. Simply connect the 2600B to the internet via the supplied LAN

cable, open a browser, type in the 2600B’s I.P. address, and begin testing. Resulting data can be

downloaded to a spreadsheet such as Excel for further analysis and formatting, or for inclusion in

other documents or presentations.

Unmatched Throughput for

Automated Test with TSP Technology

For test applications that demand the highest

levels of automation and throughput, the Model

2600B’s TSP technology delivers industry-best

performance. TSP technology goes far beyond

traditional test command sequencers… it fully

embeds then executes complete test programs

from within the SMU instrument itself. This

virtually eliminates all the time-consuming bus

communications to and from the PC control-

ler, and thus dramatically improves overall

test times.

SMU-Per-Pin Parallel Testing

with TSP-Link Technology

TSP-Link is a channel expansion bus that enables

multiple Series 2600B’s to be inter-connected

and function as a single, tightly-synchronized,

multi-channel system. The 2600B’s TSP-Link

Technology works together with its TSP technol-

ogy to enable high-speed, SMU-per-pin parallel

testing. Unlike other high-speed solutions such

as large ATE systems, the 2600B achieves parallel

test performance without the cost or burden of

a mainframe. The TSP-Link based system also

enables superior flexibility, allowing for quick

and easy system re-configuration as test require-

ments change.

Model 2400 Software Emulation

The Series 2600B is compatible with test

code developed for Keithley’s Model 2400

SourceMeter SMU instrument. This enables

an easier upgrade from Model 2400-based

test systems to Series 2600B, and can improve

test speeds by as much as 80%. In addition, it

provides a migration path from SCPI program-

ming to Keithley’s TSP technology, which when

implemented can improve test times even more.

For complete support of legacy test systems, the

Model 2400’s Source-Memory-List test sequencer

is also fully supported in this mode.

Third-generation SMU Instrument

Design Ensures Faster Test Times

Based on the proven architecture of earlier Series

2600 instruments, the Series 2600B’s SMU instru-

ment design enhances test speed in several ways.

For example, while earlier designs used a parallel

current ranging topology, the Series 2600B uses a

patented series ranging topology, which provides

faster and smoother range changes and outputs

that settle more quickly.

A Greater Measure of Conﬁdence

The Series 2600B SMU instrument design sup-

ports two modes of operation for use with a vari-

ety of loads. In normal mode, the SMU instru-

ment provides high bandwidth performance

for maximum throughput. In high capacitance

(high-C) mode, the SMU instrument uses a slow-

er bandwidth to provide robust performance

with higher capacitive loads.
