Chapter 1 Introduction
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.

Description

The NI PXIe-8101/8102 PXI Express/CompactPCI Express embedded
computer is a high performance PXI Express/CompactPCI
Express-compatible system controller. The NI PXIe-8101/8102 controller
integrates standard I/O features in a single unit by using state-of-the-art
packaging. Combining an NI PXIe-8101/8102 embedded controller with a
PXI Express-compatible chassis, such as the PXIe-1062Q, results in a fully
PC-compatible computer in a compact, rugged package.
The NI PXIe-8101 has an Intel
single core processor) with all the standard I/O and a 80 GB (or larger)
hard drive. The NI PXIe-8102 has an Intel
processor (1.9 GHz) with all the standard I/O and a 80 GB (or larger)
hard drive.
The standard I/O on each module includes DVI-I (Digital Video Interface
Integrated Analog/Digital) video, one RS-232 serial port, a parallel port,
two Hi-Speed USB ports, Gigabit Ethernet, a reset button, and a PXI
trigger.
