PXI Express Modules

The PXI Express Specification integrates PCI Express signaling into the PXI standard, which increases backplane bandwidth and enhances PXI timing and synchronization features by incorporating a 100 MHz differential Reference Clock and differential triggers. The PXI Express Specification adds these features to PXI while maintaining backward compatibility.

Chassis Guidelines

You can install NI PXI Express modules in the following PXI Express chassis slots:
  • PXI hybrid slots—Accepts either PXI modules that are hybrid slot-compatible or PXI Express modules
  • PXI Express slots—Accepts PXI Express modules
  • PXI Express system timing slots—Accepts PXI Express modules
    • Note Refer to the getting started guide for your PXI Express device and chassis documentation for more information about installing and configuring PXI Express modules.

    Using PXI Express Products with CompactPCI Express Products

    The CompactPCI/PXI Express backplane integrates PCI Express while still preserving compatibility with current PXI modules. PXI Express hybrid slots are capable of delivering signals for both PCI and PCI Express. Thus, the hybrid slot allows you to install a PXI module that uses PCI signaling or a PXI Express module that uses PCI Express signaling.
