PXIE-1084 784058-01 机箱提供17个混合外设插槽

The chassis provides seventeen (17) hybrid peripheral slots as defined by the PXI-5 PXI Express Hardware Specification: slots 2 to 18. A hybrid peripheral slot can accept the following peripheral modules:
• A PXI Express peripheral with x8, x4, or x1 PCI Express link through a switch to the system slot. Each PXI Express peripheral slot can link up to a Gen-2 x1 PCI Express, providing a maximum nominal single-direction bandwidth of 500 MB/s.
• A CompactPCI Express Type-2 Peripheral with x8, x4, or x1 PCI Express link through a switch to the system slot.
• A hybrid-compatible PXI Peripheral module that has been modified by replacing the J2 connector with an XJ4 connector installed in the upper eight rows of J2. Refer to the PXI Express Specification for details. The PXI Peripheral communicates through the backplane’s 32-bit PCI bus.
• A CompactPCI 32-bit peripheral on the backplane’s 32-bit PCI bus.
The hybrid peripheral slots provide full PXI Express functionality and 32-bit PXI functionality except for PXI Local Bus. The hybrid peripheral slot only connects to PXI Local Bus 6 left and right.

PXI Local Bus
The PXI backplane local bus is a daisy-chained bus that connects each peripheral slot with adjacent peripheral slots to the left and right.
The backplane routes PXI Local Bus 6 between all slots. Local bus signals may range from high-speed TTL signals to analog signals as high as 42 V. Initialization software uses the configuration information specific to each adjacent peripheral module to evaluate local bus compatibility.
PXI Trigger Bus
All slots on the same PXI bus segment share eight PXI trigger lines. You can use these trigger lines in a variety of ways. For example, you can use triggers to synchronize the operation of several different PXI peripheral modules. Modules can pass triggers to one another, allowing precisely timed responses to asynchronous external events the system is monitoring or controlling.
The PXI trigger lines from adjacent PXI trigger bus segments can be routed in either direction across the PXI trigger bridges through buffers. This allows you to send trigger signals to, and receive trigger signals from, every slot in the chassis. Static trigger routing (user-specified line and directional assignments) can be configured through Measurement & Automation Explorer (MAX). Dynamic routing of triggers (automatic line assignments) is supported through certain National Instruments drivers like NI-DAQmx.
