Multimeter/Data Acquisition/
Switch Systems
Integra Series systems (2700, 2701, 2750) 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. The 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 up to 500
channels/second (up to 3500 readings/second
on a single channel) will increase test
productivity.
Fast Setup and Operation
The Integra systems are fully integrated, off-the-shelf measurement and control systems. Their DMMlike 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 free ExceLINX-1A software 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.
The Advantage of Integrated Design
The Integra systems 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.
The Integra systems offer accuracy and repeatability superior to plug-in data acquisition boards,
while providing faster test times than typical
DMM/switch systems. This makes it possible to
combine higher test yields with higher test
throughput.

Install up to five input modules in the 2750 mainframe (or up to two in the 2700 and 2701 mainframes). All switch/control modules are fully enclosed in impact-resistant plastic for exceptional
ruggedness. Three connector alternatives simplify connecting the modules to DUTs. Rugged D-sub
connectors allow quick, secure connections and are especially convenient when performing routine maintenance or when the system is installed in a rack. IDC ribbon cable adapters are supplied with the Model 7701, 7707, and 7709 modules for fast, uncomplicated hookups in production test and process monitoring applications. Oversize screw-terminal connectors simplify setup
in applications that require the greatest connection flexibility. Additional D-sub and IDC ribbon
cable connector kits and pre-wired cable assemblies are sold separately.
Ethernet
The Model 2701 offers a 10/100 BaseT Ethernet connection for high speed and long distance communication between a computer and a virtually infinite number of instruments. Any PC with an
Ethernet port can connect to a single Model 2701 in a point-to-point configuration, to multiple
Model 2701s through a hub, or to multiple Model 2701s distributed on a network.
The Model 2701 Ethernet port uses the industry-standard TCP/IP socket interface. This provides data
rates up 100Mbits/sec. and allows the instrument to be located up to 100 meters from the nearest
computer or network hub in hardwired systems and miles in wireless Ethernet systems. The maximum distances between a control PC and the instruments are limited only by the size of the network.
The instrument also provides a built-in diagnostic web page for easy remote access to the Model
2701. Entering the instrument’s IP address in the URL line of Microsoft Internet Explorer will allow
communication with and control of the Model 2701. This Web page allows users to read and set network parameters, such as IP address, subnet mask, gateway, MAC address, and calibration dates, and
to send commands to and query data from the Model 2701.
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.

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 setup and
verification, manual probing, troubleshooting, and calibration,
while the rear panel inputs through the modules allow fast,
automated multiplexing and control.
• Battery-backed setup memory—Up to four different setup
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.
• Relay counting—Provides preventive maintenance of the system
and switches.
• Memory buffer—The mainframe’s non-volatile 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 date-stamp readings for later
review and interpretation.
• 2 TTL-level digital inputs—Use to implement 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 (Models 2700 and 2750)
• Ethernet and RS-232 interface (Model 2701 only)
• 3-year warranty
