Manufacturing test software NATIONAL INSTRUMENTS

PXI is a test, measurement, and control platform designed for demanding applications that require maximum uptime and a high level of reliability. The PXI specification ensures this with requirements such as a rugged Eurocard form factor and forced-air cooling. Moreover, PXI products from National Instruments are designed, manufactured, and tested with the goal of delivering the highest quality products for the most demanding applications. For example, during new chassis development, Flotherm modeling is used to optimize cooling within the chassis card cage and power supply. During the development testing stage, empirical testing is performed to ensure these cooling levels have been achieved. Another example is the fact that PXI chassis, controllers, an modules from NI undergo highly accelerated life testing (HALT) during development testing to ensure product design margins and, in turn, reliability. These, along with the many other practices that NI employs during design, manufacturing, and test, result in PXI products of the highest quality and reliability. This is evident when you examine both the product's quality and reliability specifications, for example, mean time between failures (MTBF), and the tens of thousands of systems that have been deployed into the most demanding applications around the world, such as nuclear power plant inspection. However, all electronic devices have some failure rate. Not even the most reliable electronic systems (medical monitoring equipment, data servers in financial institutions, etc) are emune to failures, rare as they may be. In order to help you reduce the risk and maximize the uptime of your PXI system, this white paper presents best practices to follow during assembly, deployment, and maintenance. Additionally, if you do experience a failure, the techniques it discusses will minimize the downtime of your PXI system.
