Precision Performance.
Accurate Data.
Repeatable Results.
Reliable Measurements. First Time. Every Time.
Qualification and performance testing is rigorous and unforgiving. Retests are
expensive in both time and money. More often, they’re not even feasible. Test data
must be captured correctly the first time. Thus, the reliability of the data acquisition
system, the accuracy of the measurements, and integrity of the data must be faultless
for each and every test. The risk is too high to compromise on the test instruments.
That’s why for decades, customers worldwide
have relied on VTI.
Our customers depend on us to deliver highly accurate data when they are faced
with their most critical testing needs. VTI systems deliver the highest performance
available in a scalable, open-architecture platform. With powerful software tools
that aid the developer in the setup and control of test configurations, errors are
minimized. These high-performance systems, whether LXI or VXI, have been proven
to consistently deliver accurate, repeatable data in applications worldwide.

and you’re feeling the pressure of time – a DAC Express system is the right solution
for you.

Intuitive software saves you valuable time.
VTI performance hardware gives you confidence
in your measurements.
Time Is Precious
When your new product introduction date is set in stone and you aren’t finished
testing, you can’t afford to waste time with tedious programming tasks. DAC Express
is fast to set up because it requires no programming. Connected hardware is
auto-identified and ready for assignment to measurements.
The Right Data The First Time
Performance validation testing of a new product requires a data acquisition system
with answers you can trust. Non-repeatable results are not results at all. With features
like superior self-calibration and certified accurate measurements, VTI’s hardware
provides all the measurement performance and reliability you need.
Data Logger Configuration
You can easily configure a wide mix of channel types using DAC Express. Common
measurements, such as temperature and strain, can be streamed to disk while
on-line monitoring displays show key values for the operator. Sometimes you need
more than just analog data. If your job requires recording digital states, relay settings,
shaft rpm, pulse train rates, or similar parameters in addition to analog signals, this
system is the answer.
Automatic Instrument Discovery
If VTI’s data acquisition instruments are powered up and connected to your PC,
DAC Express will automatically identify those resources for you. All installed signal
conditioning is also identified so there is no question about which signals you can

Set Up Channels With Table/Menu Pull-Downs
Simply click on the tabs at the bottom of the screen to display the available
measurement channels (shown below). This example screen shows three high-speed
inputs connected to accelerometers and two connected to microphones.
Select transducers from the pull-down menus are shown in the highlighted window.
The additional tabs allow you to select several types of signal conditioning for
low-speed measurements such as temperature, voltage, resistance, or strain. For
the few transducers not defined, you can easily convert the measured voltages to
engineering units using a built-in mx+b linearization routine (provided in a separate
setup window).
Keep things organized with
“Project View.” The tree view
on the left side of the screen
image shows the steps and
related documents that can
be kept with a specific test.
This is called the “Project

In the Data Recorder mode,
a pull-down menu controls
Cal Zero and Auto Cal
to completely calibrate
your test setup from A/D
to transducer. All displays
from bar graphs to XY
plots maintain calibrated
engineering units.
Select Measurement Rates
Once you’ve created the channel connections, you can set the sample rates in the
timebase screen (not shown). The channel measurement rate for high-speed digitizer
channels can be set independently from that of the scanning A/D channels. You can
also set the length of the test and the triggering conditions before starting
the test.
Just Press “Record”
It’s as simple as that. Measurements will start and stop based on the criteria specified
in the timebase setup. But, there’s more to good data acquisition than just recording.
DAC Express supports many powerful data monitoring, display and export features.

Accurate. Powerful. Easy to Use.
The EX1000 family of LXI Class A instruments are the most advanced, full-featured
data acquisition solutions available on the market today. These scalable, standalone
instruments provide superior measurement accuracy and repeatability thanks to fully
integrated signal conditioning, advanced CJC, and end-to-end self-calibration.
Flexible Channel Configuration
A wide range of transducer types, including pressure, strain, temperature, position
and voltage, can be combined in this flexible solution. Each input incorporates an
independent signal conditioning path with software-selectable filters for maximum
flexibility. Complete channel independence ensures data integrity regardless of
sample speed or input overload conditions.
End-to-End Self-Calibration
Complete end-to-end self-calibration is provided for each signal path on a
programmable basis. A highly accurate calibration source provides reference signals

be activated or deactivated on a per-channel basis. The detection mechanism is
embedded in the signal conditioning circuitry and accurately provides an open circuit
indication in the event of a broken or intermittent transducer.
Cold Junction Compensation
The heart of any truly accurate thermocouple measurement system is the CJC
implementation. These instruments combine multiple precision thermistors, a
significant thermal mass, and careful parts placement to provide world-class
measurement performance.

Precision. Accuracy. High Performance.
Highest Accuracy. Lowest Overall Hardware Costs
The compact modular EX1629 delivers superior measurement accuracy at a
cost-effective price per channel. This single instrument can perform both high-quality
static and high-speed strain gauge measurements in critical test applications. The
EX1629’s flexible design makes it easy to reuse in future test programs, resulting in
the highest return on your hardware investment. This design also keeps overall test
hardware costs down.
Any Channel. Any Bridge or Voltage Input.
The EX1629 features software-configurable strain/voltage conditioning and excitation
in a single 19-inch, 3 1/2 inch-high rackmount enclosure. This flexibility allows the
connection of quarter bridge, half bridge, full bridge, or voltage inputs to any channel,
minimizing setup time and wiring changes. There is no need to reconfigure hardware
to make measurement changes.
Performance and measurement integrity are enhanced with independent bridge
excitation per channel. Bridge excitation sources are not shared between channels;
single channel failures do not affect other channels.
Easily Combine and Measure 10,000+ Channels
For large data acquisition applications, multiple EX1629s are easily synchronized
together in a master-slave relationship via the external LXI Trigger Bus. Easy strain
gauge wiring and conditioning for both static load and vibration testing greatly
simplify high channel count test setup.
Reduce Errors and Field Wiring Costs
Integrated Transducer Electronic Data Sheet (TEDS) provides positive transducer
identification, eliminating cabling errors. Extensive testing has qualified the standard
RJ-45 telecom connector and cable as the ideal low-cost physical connection for
strain gauges. This cuts cost and makes connections quicker.
Ethernet Interface Ideal for Distributed Environments
The EX1629 can be placed at strategic points throughout the test cell, minimizing
cabling and setup time. For comprehensive, programming-free data recording, setup,
