Have
you seen your PC computer inside? Yes, perhaps. Thus you probably noted
that it is collected from modules of several producers. PC computers are
modular. Rules that enable to mix products in one computer already exist.
Extremally you can build your own PC computer and you are not limited to
one supplier. You can select modules and boards that suit you more - with
speed, quality or price. You join connectors, chain cables and fasten everything
in the box and you are ready. Simple? Not so, because you have to know
a lot of information to make correct selection of particular parts.
VXI systems are modular, too. VXI is a multivendor industry standard (IEEE 1155) for modular instrumentation. Click here to get more information about this standard. Nevertheless the situation is better with VXI than with PCs, because the size of modules and other factors are standardized more. There is even a standard for electromagnetic compatibility, which ensures, that you can combine modules in any order with no influence on functionality and accuracy. Such a standard does not exist in the PC world at all.
Modularity and functionality are two key aspects in designing today's test systems. VXI is ideal in addressing both of those requirements. Modules are designed to provide the maximum amount of functionality in a form factor that was developed as an industry standard for modularity. These instruments are used in applications ranging from manufacturing process control to aerospace and telecommunications. Test instruments are designed to provide maximum reliability and maximum flexibility in test system design.
However as the variety of VXI components grows, so does the responsibility placed on an end user. He or she must sort through the options and understand which products are best suited for his or her needs. Successful integration of a multivendor VXI system even requires more than hardware products working together at the electrical and mechanical level. The software products used to control the hardware must also work together to have a truly open system.
As a result of our free service you will get an advice listing modules you should complete your system of. Naturally you will get an explanation why we have selected particular types, what you should avoid and what is the risk induced. If you follow our instructions you get optimal results by yourselves.
