7、st function with the same military test systems, while significantly reducing the size, reduce complexity and costs, so that the Navy can be deployed in the test system strategic location, and reduce overall maintenance costs and submarine fleet logistics costs.Orbis Inc. (Orbis) is a company with 1
8、30 employees of small businesses, is headquartered in the state of South Carolina in Charleston. Its core business is the U.S. Department of Defense (DoD) to provide engineering and project management services. Orbis is also committed to conduct cutting-edge research and development projects, focusi

These systems maintenance and troubleshooting involves sub-assemblies between the module and the RFI spare parts are interchangeable. Sy

As the traditional system, all tests were carried out in a central position, the total cost of ownership will increase. In addition to the cost of transport

We have successfully built a prototype to demonstrate the new system can not only use modern testing equipment and methods, and in the premise without sacrificing functionality test systems curren

Next, we analyzed
14、the suppliers, chose NI PXI devices as the sole supplier because the company is the leader in PXI, NI offers a wide range of PXI modules to meet the needs of our test systems and technical requirements, the The company also provides a “plug and play“ environment.
