Specification.Revision 2.0 PXI-6 PXI Express Software Specification PIC MG CompactPCI Express EXP.0 R1.0 Specification PCI Express Base Specification,Revision 2.1,PCI Special Interest Group PXI MultiComputing Hardware Specification,Revision 1.0 PXI Multi Computing Software Specification.Revision 1.0PXI Express FeaturesBenefits of PXI ExpressThe PXI(PCI extensions fbr Instrumentation)industry standard,an open specification governed by the PXI Systems Alliance(PXISA),has quickly gained adoption and grown in prevalence in test,measurement,and control systems since its release in 1998.One of the key elements driving the rapid adoption of PXI is its use of PCI in the communication backplane.As the commercial PC industry has improved the available bus bandwidth by evolving PCI to PCI Express,PXI is now able to meet even more application needs by integrating PCI Express into the PXI standard.By taking advantage of PCI Express technology in the backplane,PXI Express increases the available PXI bandwidth from up to 132 MB/s to up to 8 GB/s for a more than 60 x improvement in bandwidth.PXI Express maximizes both hardware and software compatibility with PXI modules.PXI Express hybrid slots deliver both PCI and PCI Express signaling to accept devices that use PXI communication and triggering or the newer PXI Express standard.Software compatibility is maintained because PCI Express uses the same OS and driver model as PCI,resulting in complete software compatibility among PCI-based systems,fbr example PXI,and PCI Express-based systems such as PXI Express.2|Nl PXImc Devices User ManualPXI Express,like PXI,leverages from the CompactPCI specification to define a rugged,modular form factor that offers superior mechanical integrity and easy installation and removal of hardware components.PXI Express products offer higher and more carefully defined levels of environmental performance required by the shock,vibration,temperature,and humidity extremes of industrial environments.Mandatory environmental testing and active cooling is added to the CompactPCI mechanical specification to ease system integration and ensure multivendor interoperability.The demanding timing and synchronization requirements of instrumentation systems are met by the integrated features of PXI Express.Not only are the trigger bus,10 MHz system reference clock,and star trigger bus available in PXI retained by PXI Express,but new timing and synchronization features that include a 100 MHz differential system reference clock for the synchronization of multiple modules and three differential star trigger buses for the distribution of precise clock and trigger signals have been added.Differential timing and synchronization signals provide PXI Express systems with increased noise immunity and the ability to transmit clock signals at higher frequencies.Nl PXIe-8830mc OverviewFunctional OverviewThe NI PXIe-8830mc is a PXImc device1 module that allows the attachment of subsystems such as standalone instruments,PCs,or other PXI Express systems to an existing PXI Express system via a high-bandwidth,low-latency PXI Express backplane Gen2 x8 link.The NI PXIe-8830mc
