The PXI Express (PXIe) platform combines performance and flexibility to provide cost-effective test solutions to meet complex functional testing requirements in automotive, aerospace and defense, power and energy, and even commercial applications.
The ability to count and measure things is key to the human race’s success. Without the capability to perform accurate measurements, the world as we know it would simply not exist. For example, there would be no electric lighting or heating because there would be no electricity. Similarly, there would be no radios and televisions, and no movies called Planes, Trains, and Automobiles. There would be no movies at all… or planes… or trains… or automobiles.
Batteries are proliferating, along with the need for battery testing. A new isolated high voltage measurement instrument proves to deliver accurate and highly repeatable voltage measurements, especially for this application.
The road to a green-energy future is a long and winding one. Much progress has been made in using renewable resources such as wind, but many twists and turns lie ahead. Natural gas will continue to have a role to play, and small modular reactors (SMRs) offer energy-source flexibility and overcome the disadvantages of conventional nuclear plants. As the energy industry plots optimal paths forward, it must take advantage of innovations ranging from sophisticated CAD tools and digital twins to accurate, reliable data-acquisition systems.
Explore New Resources from VTI Instruments
Automated test systems for aerospace/defense programs require instruments, programmable power supplies and loads, and high-density switching systems designed for reliability, performance, and flexibility. AMETEK Programmable Power and AMETEK VTI Instruments stand ready to assist the aerospace/defense community in implementing its core testing strategy. Previously, the industry had deployed a dedicated test station for each device under test (DUT). In contrast, the core testing strategy deploys one universal test station that can test various types of DUTs. The universal test station includes large switching systems that interconnect a superset of the instruments that can test all the target DUTs.
When it comes to communications and cellular equipment, change is inevitable. Every month or so, new phones come out with new features and technology, making older models obsolete. Even the cell towers themselves are being regularly reconfigured to optimize networks.
In order to create better products, you need better means of testing. From designing a new airplane engine to making updates to the defense grid, functional tests and black box testing ensure that any new products or updates meet your requirements.
To maintain signal integrity in an automatic test system requires:
Many accelerometers used for measuring vibration include a built-in preamplifier to transform the high impedance charge output of the piezoelectric sensor into a low impedance voltage signal, typically 100-300 ohms, that can be transmitted over longer distances. To power this preamplifier, many VTI Instruments products provide an interface that complies with the Integrated Electronics Piezo Electric, or IEPE standard. Using this standard interface ensures that you can connect sensors with an IEPE interface to a VTI instrument and get good results.
