The NI PXIe-1082 is an 8-slot, 3U PXI Express chassis delivering high-bandwidth connectivity for demanding test and measurement systems. It combines a high-performance backplane with dual cooling fans and integrated power monitoring, supporting PXI Express modules across all slots and hybrid-compatible standard PXI modules in four slots. The chassis provides up to 4 GB/s total system bandwidth with per-slot x4 PCI Express connectivity, precise timing synchronization via 10 MHz and 100 MHz reference clocks, and multiple trigger architectures including differential star triggers with sub-200 ps intermodule skew.
Technical Specifications
Backplane Architecture
• One system slot with three system expansion slots; seven peripheral slots
• PXI Express and CompactPCI (PICMG 2.0 R 3.0) 3U module support
• 1 GB/s per-slot dedicated bandwidth (x4 PCI Express)
• 4 GB/s total system bandwidth
• Full compliance with PXI-5 PXI Express Hardware Specification
Timing & Synchronization
• 10 MHz system reference clock: ±25 ppm accuracy, 500 ps maximum slot-to-slot skew, 5 ps RMS phase jitter (10 Hz–1 MHz)
• 100 MHz system reference clock: ±25 ppm accuracy, 100 ps maximum slot-to-slot skew, 3 ps RMS phase jitter (10 Hz–12 kHz), 2 ps RMS phase jitter (12 kHz–20 MHz)
