National Instruments Product Guide - 2008 - (Page 17) Timing and Synchronization Modules PXI timing and synchronization modules use the trigger bus, star trigger, and system reference clock features of PXI to implement advanced multimodule and multisystem synchronization. Through shared clocks, triggers, and time references, you can vastly improve the accuracy of measurements and implement advanced clocking and triggering schemes. Control PXI trigger bus and PXI star trigger lines Synchronize multiple PXI chassis Synchronize hybrid systems with GPIB, VXI, and other instruments Learn more at ni.com/pxi Features Synchronization With PXI timing and synchronization modules, you can tightly synchronize multiple PXI systems with chassis-to-chassis skew below 100 ps. Clock Generation You can generate clocks from DC to 105 MHz with 1 µHz resolution. References High-stability OCXO and TCXO reference clocks are available with a maximum stability of 50 ppb. Data Streaming Because it is based on the high-bandwidth PCI and PCI Express buses, the PXI platform enables instruments and data acquisition modules to continuously stream data to and from high-speed RAID hard drive arrays. External RAID hard drive enclosures Up to 600 MB/s sustained reading and writing to disk Up to 12 hard drives with 3 TB total storage capacity Learn more at ni.com/pxi Features High-Bandwidth Interface PXI systems interface to the RAID hard drive arrays using cabled PCI Express. Standard File I/O NI data streaming systems support standard file I/O application programming interfaces. RAID The external RAID hard drive enclosures support multiple RAID levels, including 0, 1, and 5. ni.com 17 http://ni.com/pxi http://ni.com/pxi http://ni.com
