* Accepts PXI Express, hybrid-compatible PXI, CompactPCI Express, and CompactPCI modules
* 8 hybrid slots, 8 PXI Express slots, and 1 PXI Express system timing slot
* High performance – up to 1 GB/s per-slot dedicated bandwidth and up to 4 GB/s system bandwidth

The NI PXIe-1075 18-slot, high-bandwidth backplane is designed for a wide range of test and measurement applications and provides up to 1 GB/s per-slot dedicated bandwidth to meet high-performance needs. It has eight PXI Express slots, one PXI Express slot with system timing capabilities, and eight PXI Express hybrid slots that accept both PXI and PXI Express peripheral modules. The NI PXIe-1075 backplane incorporates all the features of the latest PXI specification, accepting both PXI and PXI Express modules. It has a built-in 10 MHz reference clock, PXI trigger bus, and PXI star trigger for PXI modules and a built-in 100 MHz reference clock, SYNC 100, and PXI differential star trigger for PXI Express modules. Providing up to 4 GB/s total system bandwidth, this high-performance backplane can meet a variety of high-throughput application needs.

* Accepts PXI and CompactPCI modules
* 3 peripheral slots
* Onboard 10 MHz reference clock and trigger routing

The NI PXI-1031 four-slot backplane is designed for a wide range of embedded, control, and test and measurement applications. It has three PXI peripheral slots and one PXI controller slot that can accept up to a four-slot-wide controller. The PXI backplane is compatible with both PXI- and CompactPCI-compliant modules. It features a low-jitter 10 MHz reference clock for device synchronization.

General Information:
Variant L1 Professional (max. 600 W)
– This backplane has been designed for all CompactPCI power supply units that conform to the PICMG 2.11 Power Interface Specification and are equipped with the P47 power connector
– Backplanes are intended for mounting in a 19″ card rack with 3 U or 6 U
– They can be installed directly on the card rack mounting channel
– Installation width is 8 HP
– Contiguous backplane placement in the 8 HP slot spacing is possible
– Features necessary for cascading and HOT-SWAP operation have been implemented
– Hartmann backplanes are completely operable as delivered
– No changes need to be made or settings to be changed by the user in the majority of cases
– Standard slot spacing is 8 HP
– Other slot spacings are available upon request
– Cascaded backplanes are preassembled and completely pre-wired for operation

Variant L1 Standard (max. 300 W)
– The “L1 Standard” variant is a lowcost alternative to the professional version described above
– Comes with the P47 connector X1, the power supply connector X0 (only on 3 U), the ATX connector X12, the utility connector X13 and the resistors and capacitors
– It does not support parallel connection of several backplanes, the System Management Bus, geographic addressing, screw-type terminal connections and the X14 power output connector
– This variant is particularly suitable in combination with variant RB of our CPCI backplane line
– All the required wiring between the power backplane and the CPCI bus can be implemented quickly and economically with an ATX and a utility cable, including polarity reversal protection
