NI PXIe-1095 PXIe, 18-Slot, Up to 24 GB/s PXI Chassis

The NI PXIe-1095 is an 18-slot PXI Express chassis built for high-performance test and measurement systems requiring sustained, high-bandwidth data transfer. It delivers up to 24 GB/s total system bandwidth via PCI Express Gen 3 backplane technology, with 11 dedicated PXI Express slots rated to 8 GB/s single-direction throughput each. Five hybrid-compatible slots and a dedicated system timing slot complete the architecture. Compliant with PXI-5 specification, the chassis supports peer-to-peer and peer-to-disk operations with advanced timing and trigger synchronization.

The platform houses two redundant, hot-swappable 900 W power supplies delivering 1644 W total capacity, tolerating AC input from 90 to 264 VAC. Per-slot power dissipation reaches 82 W maximum, with 58 W dedicated cooling capacity per slot. System controller slot current is limited to 45 A. Variable-speed fan control and two selectable cooling profiles optimize thermal management and acoustic performance across benchtop and rack installations.

Timing accuracy is exceptional. The 10 MHz system reference clock (PXI_CLK10) maintains ±25 ppm accuracy over temperature, with 250 ps maximum slot-to-slot skew; the 100 MHz reference (PXIe_CLK100 and PXIe_SYNC100) delivers ±25 ppm accuracy with 100 ps skew. An optional OCXO upgrade enhances clock stability further. External 10 MHz clock I/O via SMA connectors enables system integration. High-density trigger distribution through PXI Star trigger reaches every slot, while dedicated ports support remote inhibit and chassis monitoring.

USB 3.0 connectivity on the rear panel simplifies integration. Chassis dimensions measure 6.97 x 17.54 x 18.25 inches (H x W x D), with weight of 35.2 lb on single power supply configuration. Modular design, hot-swappable components, and thermal monitoring reduce mean time to repair.
