CONNECT DUT
Series 2600A System SourceMeter instruments are Keithley’s latest I-V source-measure instruments for
use as either a bench-top I-V characterization tool or as a building block component of multi-channel
I-V test systems. For bench-top use, Series 2600A instruments feature an embedded TSP Express
Software Tool that allows users to quickly and easily perform common I-V tests without programming or installing software. For system level applications, Series 2600A’s Test Script Processor (TSP)
architecture along with new capabilities such as parallel test execution and precision timing provides
the highest throughput in the industry to lower the cost of test.
Series 2600A System SourceMeter instruments replace the popular Series 2600 System SourceMeter
instruments with a superset of features. The Series 2600A provides backward code compatibility to
the Series 2600, so customers can drop-in replace Series 2600 with Series 2600A.
Quick and Easy Lab or Bench-Top Use
For lab or bench-top use, the Series 2600A SourceMeter instruments offer a complete I-V measurement solution with unmatched ease of use, capability, and flexibility to simplify the process of making high-performance measurements and speed time to market for customers.
The user can easily connect the Series 2600A SourceMeter instrument to the PC by using the Ethernet
cable (provided with the instrument) and by entering the IP address in the web browser to automatically load the built-in LXI web page. TSP Express can then be launched from the built-in LXI web
page, so neither software installation nor GPIB connection are needed. The TSP Express Software
Tool provides an intuitive user interface to quickly set up and run basic and advanced tests including
nested step/sweeps, pulse sweeps, and custom sweeps for device characterization applications. For
applications where single point I-V source-delay-measure is all that is needed, the tool also provides
an interface to quickly configure and measure discrete points. The data can then be viewed in graphical or tabular formats and can be readily exported to a .csv file for use with spreadsheet applications.
For more advanced test requirements, the automatic script generation feature simplifies the process
of writing custom programs.

Unmatched Throughput and
Flexibility for High Performance
I-V Test Systems
TSP technology provides remarkable capabilities
when the Series 2600A is integrated as part of a
multi-channel I-V test system.
First, the embedded scripting capability allows
for complete test scripts to be run by the instrument. Test scripts are complete test programs
based on an easy to use but highly efficient and
compact scripting language called ‘Lua’ <www.
lua.org>. Since the test scripts can contain any
sequence of routines that can be executed by
conventional programming languages (including
decision making algorithms), this feature allows
entire tests to be managed by the instrument
without sending readings back to the PC for
decision making. This means that delays due to
GPIB traffic congestion are eliminated and overall test times are greatly improved.
Second, TSP technology offers “mainframe-less
channel expansion.” The TSP-Link ­channel
expansion bus (which uses a 100 Base T
Ethernet cable) allows multiple Series 2600A
instruments (and other TSP instruments) to
be connected in a master-slave configuration
and behave as one integrated system. TSP-Link
supports up to 32 units or 64 SMU channels
per GPIB or IP address. This provides virtually
unlimited channel count, allowing a system to
be scaled to fit the particular requirements of
an application.

Parallel testing with the Series 2600A
Parallel Test Capability
As the next evolutionary step in TSP technology,
the Series 2600A takes system level performance
to a new height with parallel testing capability.
This feature allows customers to test multiple
devices in parallel to meet the high throughput
requirements of production test and advanced
semiconductor lab applications.
Parallel test capability enables each instrument
in the system to have the ability to run its own
complete test sequence. Hence, the number of
tests that can be running in parallel on a Series
2600A system can be as many as the number of
instruments in the system. In contrast, most conventional test systems run a single thread of the
test usually on the controller PC instead of the
instrument itself.
This parallel test capability allows Series 2600A
systems to behave as a fully multi-threaded test
environment. Testing multiple devices at the
same time means dramatically improved test
throughput and reduced overall cost of test.
Tight Timing and Synchronization
Today’s test engineers are challenged with
testing increasingly more complex and more
sensitive devices that require precision timing
and synchronization among all test instruments
involved. Whether the test is to synchronize electrical and optical tests of an optoelectronic component or to ensure that the same stress times
are applied to the different pins of an advanced
semiconductor device, providing precision timing and synchronization between SMU channels
(and external instruments) has become a critical
requirement.
Scalable, integrated source and measure solutions
Series 2600A
A high performance hardware driven trigger
model allows timing at each I-V source-measure
step to be controlled precisely and operations
between SMU channels and/or external instrumentation to be synchronized at hardware
speeds (<500ns).
<500ns
Additionally the Series 2600A system can be
reconfigured via software, without rewiring, to
match different devices with different pin-layouts
to appropriate SMU-per-pin configurations.

SMU2
SMU4
All channels in the system are synchronized
to under 500ns.

Series 2600A
Third-generation SMU design
ensures faster test times
Based on the proven architecture of earlier
Series 2600 instruments, the Series 2600A’s new
SMU design enhances test speed in several ways.
For example, while earlier designs used a parallel current ranging topology, the Series 2600A
uses a patented series ranging topology, which
provides faster and smoother range changes
and outputs that settle more quickly. The new
Series 2600A SMU design supports two modes
of operations for use with a variety of loads. In
normal mode, the Series 2600A SMU provides
high bandwidth performance for maximum
throughput, while in high capacitance (high-C)
mode, the SMU uses a slower bandwidth in
order to provide robust performance with higher
capacitive loads.
Each Series 2600A SMU channel offers a highly
flexible, four-quadrant source coupled with precision voltage and current meters.
Each channel can be configured as a:
• Precision power supply
• True current source
• DMM (DCV, DCI, ohms, power, with 5½-digit
resolution)
• Electronic load (with sink mode capability)
• V or I pulse generator (Pulse width: 100μs
and longer)

Series vs. parallel ranging topologies
All A/D converters in the Series 2600A instruments are both high speed and high precision
for maximum flexibility.
All Series 2600A instruments provide four-quadrant operation and can be connected in series or
in parallel to extend their dynamic range. They
measure voltage and current simultaneously
with up to 5½-digit resolution, and they display
voltage, current, resistance, or power readings.
Two analog-to-digital converters per channel
(one for I, one for V) can run simultaneously,
providing precise source-readback without sacri­
ficing test throughput. These A/D converters
offer the flexibility of programmable integration
rates, allowing the user to optimize for either
high speed (>20,000 rdgs/s at 0.001 NPLC setting) or for high resolution (up to 24 bits at 10
NPLC setting) measurements.
Digital I/O Interface
A back panel port on every Series 2600A instrument provides 14 bits of universal digital I/O
to link the instrument to a variety of popular
component handlers and/or probe stations.
These I/O lines are also backward-compatible
with Keithley’s earlier Trigger-Link instrument
triggering technology. These lines simplify integrating Series 2600A instruments into systems
that employ other electrical, mechanical, optical,
or RF equipment.
Current arbitrary waveforms maximum output
update rates: 12,500 samples/second.

TSP-Link Trigger Lines
The TSP-Link bus supports dedicated trigger
lines. This means synchronous operations
between multiple Series 2600A and other TSP
instruments, such as Series 3700 DMM/Switch
Systems, that are connected via the TSP-Link bus
can be achieved without the need for additional
­trigger connections.

SUPPLEMENTAL INFORMATION
1.888.KEITHLEY
Each SourceMeter instrument has two TSP-Link connectors to facilitate chaining instruments
together.
• Once SourceMeter instruments are interconnected via TSP-Link, a computer can access all
of the resources of each SourceMeter instrument via the host interface of any SourceMeter
instrument.
• A maximum of 32 TSP-Link nodes can be interconnected. Each SourceMeter instrument
consumes one TSP-Link node.
TIMER: Free running 47-bit counter with 1MHz clock input. Reset each time instrument powers
up. Rolls over every 4 years.
Timestamp: TIMER value automatically saved when each measurement is triggered.
Resolution: 1µs.
Accuracy: ±100ppm.
Series 2600A specifications
SYSTEM EXPANSION: The TSP-Link expansion interface allows TSP enabled instruments to
­trigger and communicate with each other. See figure below:

FRONT PANEL INTERFACE: Two-line vacuum fluorescent display (VFD) with keypad and rotary knob.
Display:
• Show error messages and user defined messages
• Display source and limit settings
• Show current and voltage measurements
• View measurements stored in non-volatile reading buffers
Keypad Operations:
• Change host interface settings
• Save and restore instrument setups
• Load and run factory and user defined test scripts (i.e. sequences) that prompt for input
and send results to the display
• Store measurements into non-volatile reading buffers
PROGRAMMING: Embedded Test Script Processor (TSP) 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 (e.g. branching, looping,
math, etc.). Able to execute high speed test scripts stored in memory without host intervention.
Minimum Memory Available: 16MB (approximately 250,000 lines of TSL 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:

CVI, etc.
READING BUFFERS: Dedicated storage area(s) reserved for measurement data. Reading buffers
are arrays of measurement elements. Each element can hold the following items:
• Measurement
• Measurement status
• Timestamp
• Source setting (at the time the measurement was taken)
• Range information
Two reading buffers are reserved for each SourceMeter channel. Reading buffers can be filled
using the front panel STORE key and retrieved using the RECALL key or host interface.
