Reduce Life Cycle Costs with Scalable Common Core
Solutions for ATE
Common core solutions deliver saleable, reusable instrumentation
building blocks that can be leveraged across the entire corporation
A scalable common core can be thought of as a group of essential signal switching and synchronized instrumentation that can be used across a broad range of test applications. For example, most electronic test applications require signal switching to route power to excite the device under test, as well as connect different stimuli and response instrumentation to verify performance. A common switching core is generally comprised of high current, high-fidelity signal, and general purpose signal routing with multiplexers, matrices, and discrete switching. The same can be said for instrumentation with the core instrumentation including digitizers, signal sources, signal conditioning and digital input/output.
A properly architected common core approach can change the way test system development is viewed in the organization, adding value throughout the product's life cycle. Systems can be easily scaled to test a wide varietys of products ranging from low to high I/O requirements, allowing initial investments in core hardware and software to be leveraged across multiple programs.
Scalable Common Core for ATE
This approach reduces overall test development costs while providing exceptional scalability, flexibility, and reusability as well as providing the ability to control costs as test systems age and the service life of equipment is extended. Basing solutions on open-architecture hardware and software can ensure a smooth transition when hardware becomes obsolete or unable to address expanded test requirements. TPS (test program set) requalification can be minimized by limiting the impact that any single device will have on the system when updates or replacements are made.
VTI's EX1200 Multifunction Instrumentation Suite is an ideal general purpose common core solution that has been adopted across the industry, most recently by LMCO for the US Navy's eCASS test system. This suite delivers exceptional signal switching flexibility and performance, along with a wide variety of signal generation and measurement capability. The EX7000 RF/Microwave Signal Routing Suite extends these capabilities to high frequency applications providing the advantages of a COTS solution with innovative web-based tools designed to save development time and programming efforts, while simplifying manufacturing and long-term support activities.

Improve Product Reliability with Recognized Signal
Switch systems that lack signal transparency destroy signal integrity impacting product reliability and production test costs
Signal switching is the critical link in most automatic test systems (ATE), and the overall performance of the test system depends heavily on the ability of a switch to route signals with minimal distortion. Switch systems that lack signal transparency destroy signal integrity. So why invest in expensive instrumentation and then spend hours processing distorted signals?
Signal switching is the critical common core subsystem in many designs, and
the overall performance of the test system depends on the ability of a switch
to route signals through a system with minimal distortion. Choose the wrong switch, and you could be compromising the quality of the test results your
The EX1200 Multifunction Instrumentation Suite incorporates precision
switching designed to deliver high performance signal routing from DC to
RF/microwave to light; an ideal core switching solution.
Performance is maximized by:
- Integrating shield planes to guard against noise and interference
- Preserving impedance matching throughout the entire signal path
to guard against signal reflections
- Maintaining trace separation to minimize crosstalk and
- Incorporating robust connectors to ensure signal connections
- Utilizing high density layout techniques to reduce overall footprint
|VTI has decades of proven switching experience testing
the most complex products in the industry; this is demonstrated
in every major ATE system worldwide.

Power Generation Industry Benefits from Compact, Distributed DAQ
Precision measurements and fast test setup results in improved
reliability and lower costs
Leading suppliers of power generation and energy delivery products require cutting edge technology and superior performance to meet the world's most demanding energy requirements. Gas turbine systems deliver auxiliary electric power generation to manage peak loading conditions when demand fluctuates or when outages occur in support of customers such as hospitals and first responders who cannot afford an outage.
Therefore, testing is a key aspect of gas
turbine manufacturing to ensure
reliability and efficiency. Testing occurs
both at the manufacturing facility and
while in the field; therefore, the data
acquisition system must be easily setup,
capable of being distributed around the
test article, and reliable when exposed
to a wide range of environmental test conditions. The most common
measurements include temperature
(inlet/outlet gas), gas pressure, loads,
and torque, and must be measured by a common data acquisition system.
VTI's EX1000A Integrated Data Acquisition Suite provided the ideal distributed measurement solution. Leveraging advanced functionality including internal self-calibration, precision over-the-wire synchronization with LXI-based IEEE-1588, and support for multiple transducer types, the manufacturer was able to reduce test time and improve product reliability.
