A GREATER MEASURE OF CONFIDENCE

Integra Series

Model 2700 Multimeter/
Data Acquisition System

HIGH PERFORMANCE DATA ACQUISITION AND CONTROL SYSTEM

A complete solution for PC-based

multi-point measurement and control

TIGHT SWITCHING-AND-MEASUREMENT INTEGRATION

Keithley’s patented measurement
engine provides true 61⁄2- digit (22-bit)
performance at higher reading rates.

Typical 6

1

⁄2-digit meters only deliver
51⁄2-digit (<18-bit) performance under
similar conditions.

Engineers trust Keithley to provide
best-in-class measurement
performance. In many cases, our
products provide up to 10X better
performance at equivalent
reading rates or up to 10X
greater speed at equivalent
measurement performance. Our
patented A/D converter and high
performance signal conditioning
circuitry make this possible.

Get a DMM, a switch mainframe,
and a data acquisition/control system
for the price of a PC plug-in board

The Model 2700 Multimeter/Data Acquisition System
combines the functionality and high channel count of a switch
mainframe with the accuracy, convenience, and traceability of a
true 61⁄2-digit (22-bit) DMM. It packs all these capabilities into a
compact half-rack unit at a price that’s comparable to a high
performance data acquisition board. Keithley’s growing family of
Integra Series plug-in modules gives the Model 2700 the
industry’s lowest per-channel installed cost in a high performance
data acquisition and control package. Mix or match any two
modules to get up to 80 differential channels of multiplexed
measurement and control. That means significantly more
channels in less space than competing solutions.

An astonishing range of functions
and built-in signal conditioning

Each channel of the Model 2700 can be configured separately for
any of 14 measurement functions and provides built-in signal
conditioning. The Model 2700’s high noise isolation up to 1000V
allows it to measure virtually any electrical or physical parameter
with high accuracy:

• DC volts • DC current

• Temperature measurements • AC volts

with thermocouples, RTDs, • Frequency
or thermistors • Period

• 2-wire Ω • AC current

• 4-wire Ω • Event counter/totalizer

• Continuity • Digital I/O

Perform system level control functions

Optional plug-in modules allow the Model 2700 to manage a
variety of system control tasks:

• Actuate indicator lights and/or relays to provide alarm limit

status, and directly interface with mechanical systems
through open-collector digital I/O.

• Control power to the DUT, switch in or change loads, and

perform general signal routing through isolated switching.

• Bias the DUT or perform analog control through dual ±12V

analog output ports.

• Route DC, AC, or RF signals from the DUT to other test

equipment in the rack.

Wide testing flexibility

This economical, easy-to-configure solution is widely used in
applications like temperature logging, precision measurement and
control, and mixed signal data acquisition for product develop­ment, ATE, component testing, and process monitoring. The
plug-in approach eliminates the triggering, timing, and processing
issues that often complicate building systems from separate
instruments and switches. The tight switching-and-measurement
integration also helps reduce test time significantly. That means
higher throughput and a better return on equipment investment.

Powerful software options

The Model 2700 is compatible with a variety of software options to
match a variety of test programming needs. For example, the free
TestPoint runtime offers basic datalogging capabilities. This start­up utility can be modified with the powerful TestPoint application
development package. Optional ExceLINX-1A software makes it
easy to acquire data directly into an Excel spreadsheet. Free IVI
(VISA-based) drivers simplify developing fully custom programs in
Visual Basic, C/C++, LabVIEW, LabWindows/CVI, or TestPoint.

If there’s a power failure, the battery-backed set-up
memory and non-volatile RAM data storage means
scans can automatically be resumed right where
they stopped when power returns.

On-board statistical analysis is
available at the push of a button,
including channel average and
ratio, mX+b scaling, min, max,
average, and standard deviation.

Its familiar DMM-like front
panel scheme makes the
Model 2700 easy to use on
the bench or in the rack.
Select or change functions
with the press of a button.

Front panel input jacks
simplify manual probing,
troubleshooting, and
calibration. Includes
1000V protection in case
of accidental overload.

Non-volatile memory stores up to
55,000 time-stamped readings.

Rugged 50-pin D-sub connectors ensure
dependability and quick setup/teardown
in production test racks.

Built-in open-collector
digital I/O lines provide
for control, external
triggering, and HI/LO
alarm/limit ouputs.

Screw terminals use
oversize connectors for
easier, mistake-free wiring.

GPIB and RS-232

communications are standard.

Built-in relay cycle counters on each
module for ease of maintenance.

A variety of measurement and
control modules makes it simple to
mix, match, and change input
signals or control lines as needed.
Install up to two modules at a time
to create a “mini-ATE” system with
up to 80 channels.

NON-VOLATILE MEMORY

High ease of use meets

high measurement accuracy

Ideal for production testing

Use the Model 2700 for high throughput production testing of
multiple points on a DUT and/or testing multiple DUTs in batch
mode. D-sub and SMA rear panel connectors make it fast and
easy to disconnect the Model 2700 from the test fixture. Free
instrument drivers designed for use in a variety of popular
Application Development Environments simplify creating custom
systems for production test.

Versatile enough for environmental
stress, burn-in, and QA testing

The Model 2700 is ideal for both short- and long-term monitoring
and characterization tasks. It’s immune to power failures, resuming
scanning where it left off when power is restored–all set-up
information is battery backed and data is stored in non-volatile
RAM. Input channels can handle virtually any input while its digital
output lines can trigger external alarms or perform other controls
independent of a PC.

A DMM-like front panel, half-rack footprint, 80-channel capacity,
outstanding measurement performance, and low cost make the
Model 2700 ideal for R&D applications. The free TestPoint™
runtime start-up software included with the Model 2700 and the
economical ExceLINX-1A add-in utility provide basic datalogging
capabilities, so it’s easy to get new applications “Up & Running”
quickly and inexpensively.

High channel count measurement and control solutions

While the Model 2700 offers the capacity needed to handle
applications with up to 80 channels, many applications require
hundreds of switch/control channels. For these cases, the
five-slot, 200-channel Model 2750 Multimeter/Switch System is
often the perfect size. Built on the same measurement platform,
the Model 2700 and Model 2750 share many of the same capabilities
and programming commands. The Model 2750 also offers low-ohms

measurement capabilities with 1µΩsensitivity. All the switch/control

modules and software work in both mainframes. This high
compatibility also makes it easy to migrate applications from the
Model 2700 to the Model 2750 as new test needs emerge or the
number of test points grows.
