The Model 2750 Multimeter/Switch System is an affordable
alternative to traditional high-channel-count test solutions like
rack-and-stack systems, dataloggers/recorders, VXI/PXI
systems, and plug-in card-based data acquisition equipment.
Like our popular Model 2700 Multimeter/Data Acquisition
System, it builds upon the powerful Integra Series platform.
The Model 2750 brings together high-speed measurement,
switching, and control capabilities for optimizing test processes
for a fraction of the cost of alternative solutions.

Modular platform handles today’s and
tomorrow’s applications

The system's flexible, five-slot mainframe combines a 6

1

⁄2-digit,
14-function DMM with support for up to 200 channels of
two-pole switching and multi-channel analog/digital I/O control.
This tight integration simplifies system design while it minimizes
rack space requirements. It also allows the Model 2750 to scan
and measure more than 200 channels per second, ensuring
shorter test times and greater productivity than competitive
approaches. Currently, the Model 2750 supports nine optional
plug-in switch/control modules and additional modules are
already in development. Up to five modules can be mixed or
matched to provide the combination of switching and control
capabilities today's ATE and data acquisition systems demand.
For the flexibility needed for tomorrow's applications, the
Model 2750's on-board flash memory can be reprogrammed to
support new Keithley modules as they are introduced.

Multi-channel low ohms measurements
you can trust

Expanded resistance measurement ranges allow the Model 2750
to address applications that normally require costly and complex
micro-ohmmeters, such as precision milli- or micro-ohm
measurements of connectors, harnesses, squibs, sensors,
semiconductors, and other low-ohms devices. Production-floor
features such as open test lead indication and an offset

compensation mode help eliminate troublesome "false failures"
than can result from problems with test stand wiring, connections,
relays, or cabling. The built-in 20mV clamp helps protect
sensitive DUTs from damage and prevents self-heating errors
during testing. The Model 2750 can also handle series lead
resistances of up to 80% of range and still meet specification—
this important capability helps ensure measurement integrity in
large, multipoint test system applications.

Benefits of an integrated design

The Model 2750 offers a variety of advantages over existing
solutions for ATE and data acquisition applications. For
example, its 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. Its 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 2750 offers
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.

and a modular architecture

SIMPLE TO MIX, MATCH, AND CHANGE

The Model 2750 supports nine different plug-in switch/control
modules, including those originally developed for the Model
2700 two-slot system. Any combination of five modules can
be installed at any time to match the test requirements. At
power-up, the mainframe automatically detects which modules
are installed, minimizing set-up time. To allow for timely
preventive maintenance for modules and enhance system up­time, the Model 2750 mainframe automatically logs the number
of relay closures on a memory chip built into each module.

MIXED SIGNAL CAPABILITIES

While the Model 2750 offers
the capacity needed to handle
high-channel-count testing, many
applications require just 80 switching or control channels or
less. For these cases, the two-slot Model 2700 Multimeter/Data
Acquisition 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. All
the switch/control modules 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.

Matrix or Multiplexer

A matrix switch is the most versatile type of
system switching—any input can be connected to
output, singly or in combination. A multiplex
switch connects one instrument to multiple
devices under test or multiple instruments to
one device under test. To find out more:
