Integra Series products combine precision measurement, switching, and control in a single, tightly integrated enclosure for either rack-mounted or benchtop
applications. These cost-effective, high performance test
platforms offer affordable alternatives to separate DMMs
and switch systems, dataloggers/recorders, plug-in card
data acquisition equipment, and VXI/PXI systems.
Integra Series plug-in switching and control modules
offer unmatched flexibility and testing efficiency for a
wide range of industries and applications. System
builders can create test solutions with a combination of
channel count, cost per channel, and system performance unmatched by any other single-box measurement
system. The input modules provide the flexibility to
vary the channel count from 20 to 200 (2-pole), apply a
stimulus to the device under test, route signals, control
system components, and make precision measurements
with up to 14 functions. Robust digital I/O capabilities
can be used for triggering, handshaking with other
automation equipment, and alarm limit outputs. Scan
rates of more than 200 channels/second (up to 2500
readings/second) increase test productivity.

Fast Setup and Operation
The Model 2700 and Model 2750 are fully integrated, off-the-shelf measurement and control systems.
Their DMM-like interfaces make it easy for users to collect data and/or perform troubleshooting within
minutes of installation and startup. Once sensor or DUT leads are hooked to the instrument’s input, use
the front panel controls to select the measurement function, range, filtering, scaling, trigger source, scanning sequence, alarms, and more. The TestPoint runtime start-up software included with both the Model
2700 and 2750 makes it easy to configure and use the system in a graphical “point-and-click” environment. This gives developers the basic tools needed to create a simple application without writing program code. If the application demands greater functionality, this free runtime can be modified with the
TestPoint software application package (sold separately).
The Advantage of Integrated Design
The Model 2700 and 2750 offer a variety of advantages over existing solutions for ATE and data acquisition
applications. For example, their flexible modular architecture and integrated measurement, switching, and
control capabilities save rack space by reducing the number of separate instruments needed. This design
also simplifies expanding the system as the number of channels grows or re-purposing it as new test
requirements evolve. Integrated signal conditioning, scaling, stimulus, filtering and I/O capabilities eliminate the need for external circuitry when designing and building data acquisition systems. This architecture also makes it unnecessary to open the computer to install plug-in boards. The Model 2700 and 2750
offer accuracy and repeatability superior to plug-in data acquisition boards and VXI/PXI systems, while
providing faster test times than typical DMM/switch systems. This makes it possible to combine higher
test yields with higher test throughput.

Important Features and Benefits
• Full per-channel configurability—Each channel
can be independently configured for making measurements. The parameters that can be chosen for
each channel include speed, range, resolution,
number of power line cycles (NPLC), filtering type,
offset compensation, math functions to be displayed, CJC type, RTD type, frequency gate time,
“m” and “b” values in mX + b format, HI/LO limits,
low Ω (Model 2750 only), ratio calculation, and
thermistor type.
• Channel monitor feature—Monitor any specific
input channel on the front panel display during a
scan. This feature can also serve as an analog trigger to initiate a scan sequence based on some
external factor, such as a temperature rising above
a pre-set limit. Only the data of interest is acquired,
so there’s no need to spend hours searching
through reams of normal readings to find anomalous data.
• Front/rear switch—Switching between the front
and rear panel measurement inputs is as easy as
pressing a button. Users can select the front panel
inputs for tasks such as system set-up and verification, manual probing, troubleshooting, and calibration, while the rear panel inputs through the
modules allow fast, automated multiplexing
and control.
• Battery-backed set-up memory—Up to four different set-up configurations can be stored in onboard
memory. If the line power fails during a scan, the
system will resume scanning where it stopped
once power is restored.
• 110K reading data buffer—The mainframe’s nonvolatile wrap-around reading memory allows continuous, unattended datalogging over long periods—data in the buffer can be transferred to a PC
controller automatically as new data is acquired.
The real-time clock can be used to time- and datestamp readings for later review and interpretation.
• 2 TTL-level digital inputs—For implementing external triggers to initiate a scan sequence.
• 5 “per-channel” HI/LO alarm limit TTL outputs —
Trigger external alarms or perform other control
functions without a PC controller.
• Dry circuit ohms (20mV clamp)—Protects sensitive
devices from damage and prevents self-heating
errors during testing (Model 2750 only).
• Virtual channel—Stores the results of channel-to
channel ratio and average math operations.
• Onboard statistical analysis—Mathematical functions available at the push of a button are channel
average, mX+b scaling, minimum, maximum, average, and standard deviation.
• GPIB and RS-232 interfaces
• 3-year warranty

Temperature Capabilities
Integra Series mainframes support three major types of temperature sensors with built-in
signal conditioning and 300V isolation: thermocouples, RTDs, and thermistors. To begin
using a sensor, simply hook it up and the instrument does the rest. If a thermocouple is
broken or disconnected, the instrument will alert the operator. The mainframes also support three methods for cold-junction compensation (CJC): automatic (built-in), external
(built-in), and simulated.
Software Solutions
Whether the task calls for a simple start-up package to acquire
several channels of data or the tools to create a fully custom
acquisition and analysis solution, Keithley has the software needrunning
ed to get the most performance from a Model 2700 or 2750
Multimeter/Switch System. Our broad range of software solutions s o f t w a r e
makes it easy to get applications “Up & Running” quickly and economically.
&
Our free start-up
software package
provides basic datalogging capabilities,
so a system can be
up and running
almost immediately. It
also can be used to
configure instrument
functions. Data from
multiple channels
from a single instrument can be saved to
disk; up to eight
channels of data can
be graphed automatically and multiple
configurations can be
saved to disk.
The new version of
ExceLINX is an economical, easy-to-use,
add-in utility for
Microsoft Excel.
Within minutes of
installing ExceLINX1A on a PC, users
can acquire data
directly from the
Model 2700 or 2750,
then employ Excel’s
graphics, charting,
and analysis capabilities to turn that data
into useful information. No programming
is required to use it—
a few mouse clicks
are all it takes to configure channels, set
parameters, and get
your measurements
into Excel.
