The NI PXIe-1071 chassis kit consists of a low-cost, compact 4-slot chassis featuring a 4-slot-wide system controller slot, which can accept either an embedded controller or a remote controller, and three peripheral slots. The NI PXIe-1071 offers the flexibility to populate each peripheral slot with either a PXI Express module or PXI module. In addition, it features compact, rugged packaging and quiet operation, which make it ideal for portable, desktop, and industrial control applications.

This chassis enables high-bandwidth systems and provides the flexibility you need to work with both PXI and PXI Express modules. The NI PXIe-1071 features three PXI Express slots and four PXI hybrid-compatible slots. PXI hybrid-compatible slots can accept either a PXI Express module or a standard PXI module.

The PXI Express system slot offers three x4 PCI Express links (1 GB/s single direction per link) connected to the three peripheral slots. In addition, there is one x1 PCI Express link to a PCI Express-to-PCI translation bridge on the backplane. The three PXI Express hybrid slots deliver connectivity to either a x4 PCI Express link or to the 32-bit, 33 MHz PCI bus on the backplane.

For PXI modules, the NI PXIe-1071 backplane is fully compliant with PXI timing and synchronization standards. The chassis includes a 10 MHz reference clock with an accuracy of ±25 parts per million (ppm), less than 5 ps jitter, and a maximum slot-to-slot skew of 250 ps. For triggering and handshaking needs, the NI PXIe-1071 offers the PXI trigger bus.

For PXI Express modules, in addition to PXI timing and synchronization features, the NI PXIe-1071 backplane delivers a differential 100 MHz reference clock with an accuracy of ±25 ppm, less than 3 ps jitter, and a maximum slot-to-slot skew of 100 ps. The NI PXIe-1071 does not offer a system timing slot, which provides the ability to import/export the 10 MHz clock and PXI triggers. It also does not provide a star trigger. For more advanced timing and synchronization, consider one of the high-performance NI PXI Express chassis.

The compact, rugged, and portable NI PXIe-1071 weighs 13.1 lb, making it ideal for portable applications. It features an AUTO/HIGH fan-speed selector that provides a HIGH fan-speed setting to maximize cooling and AUTO fan setting to minimize acoustic emissions. When set to AUTO, the NI PXIe-1071 chassis monitors air intake temperature and adjusts the fan speed accordingly. When set to AUTO in an environment with an ambient temperature of 25 °C, the sound pressure level measured at the operator interface is only 48.4 dBA.
