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.
NI PXIe-8133
Description
The NI PXIe-8133 PXI Express/CompactPCI Express embedded computer
is a high bandwidth PXI Express/CompactPCI Express-compatible system
controller. The NI PXIe-8133 controller integrates standard I/O features
in a single unit by using state-of-the-art packaging. Combining an
NI PXIe-8133 embedded controller with a PXI Express-compatible
chassis, such as the NI PXIe-1082, results in a fully PC-compatible
computer in a compact, rugged package.
The standard I/O on each module includes DVI-I video, one RS-232 serial
port, a parallel port, four high-speed USB 2.0 ports, a PCI-based GPIB
controller, two Gigabit Ethernet connectors, a reset button, and
PXI Express triggers.
The NI PXIe-8133 has a quad-core Intel Core i7 Processor 820 QM, Dual
Channel DDR3, 1333 MHz memory controller, all the standard I/O, and an
integrated hard drive. It also has an ExpressCard/34 expansion slot.
