2 ExpressCard Standard, PCMCIAPXI Express FeaturesBenefits of PXI ExpressThe PXI (PCI eXtensions for Instrumentation) industry standard, an open specificationgoverned by the PXI Systems Alliance (PXISA), has quickly gained adoption and grown inprevalence in test, measurement, and control systems since its release in 1998. One of the keyelements driving the rapid adoption of PXI is its use of PCI in the communication the commercial PC industry has improved the available bus bandwidth by evolving PCI toPCI Express, PXI is now able to meet even more application needs by integrating PCI Expressinto the PXI standard. By taking advantage of PCI Express technology in the backplane, PXIE xpress increases the available PXI bandwidth from up to 132 MB/s to up to 8 GB/s for amore than 60x improvement in Express maximizes both hardware and software compatibility with PXI modules.

3 PXIE xpress hybrid slots deliver both PCI and PCI Express signaling to accept devices that usePXI communication and triggering or the newer PXI Express standard. Software compatibilityis maintained because PCI Express uses the same OS and driver model as PCI, resulting incomplete software compatibility among PCI-based systems, for example PXI, and PCIE xpress-based systems such as PXI Express, like PXI, leverages from the CompactPCI specification to define a rugged,modular form factor that offers superior mechanical integrity and easy installation and removalof hardware components. PXI Express products offer higher and more carefully defined levelsof environmental performance required by the shock, vibration, temperature, and humidityextremes of industrial environments. Mandatory environmental testing and active cooling isadded to the CompactPCI mechanical specification to ease system integration and ensuremultivendor | | NI PXIe-8840 Quad-Core User ManualThe demanding timing and synchronization requirements of instrumentation systems are metby the integrated features of PXI Express.

4 Not only are the trigger bus, 10 MHz systemreference clock, and star trigger bus available in PXI retained by PXI Express, but new timingand synchronization features that include a 100 MHz differential system reference clock forthe synchronization of multiple modules and three differential star trigger buses for thedistribution of precise clock and trigger signals have been added. Differential timing andsynchronization signals provide PXI Express systems with increased noise immunity and theability to transmit clock signals at higher PXIe-8840 Quad-CoreDescriptionThe NI PXIe-8840 Quad-Core PXI Express/CompactPCI Express embedded controller is ahigh-performance PXI Express/CompactPCI Express-compatible system controller. TheNI PXIe-8840 Quad-Core controller integrates standard I/O features in a single unit by usingstate-of-the-art packaging. Combining an NI PXIe-8840 Quad-Core embedded controller witha PXI Express-compatible chassis, such as the NI PXIe-1085, results in a fully PC-compatiblecomputer in a compact, rugged NI PXIe-8840 Quad-Core has an Intel Core i7 5700EQ processor ( GHz quad-coreprocessor), all the standard I/O, and a 320 GB (or larger) hard drive.
