NI PXIe-1075 18‑Slot PXI Express Chassis

Product Brief Description

The NI PXIe-1075 is an 18-slot high-bandwidth PXI Express chassis designed for mixed PXI and PXIe modular instruments. It features a high-performance PCIe switched backplane, integrated precision timing and synchronization bus, and modular hot-swappable power/fan shuttle. It supports RF transceivers, high-speed digitizers, FPGA modules and multi-channel I/O cards, widely deployed for 5G, radar, aerospace, semiconductor and production test systems. It is a perfect chassis match for the PXIe‑5842 VST.

Product Features

• 18-slot total: 1 system controller slot, 1 dedicated timing slot, 9 native PXIe slots, 8 hybrid PXI/PXIe slots
• Switched PCIe backplane, up to 1 GB/s per-direction bandwidth per x4 PCIe link
• Built-in timing resources: 10 MHz PXI_CLK10, 100 MHz differential PXIe_CLK100, SYNC100, star trigger and differential star trigger (DSTAR)
• Rear BNC 10 MHz reference I/O for external clock locking, good for multi-chassis phase coherent systems
• Modular power supply shuttle with integrated fans, hot-replaceable, MTTR under 5 minutes
• Universal AC input 90–264 VAC, temperature-controlled variable speed fans for low noise
• Rear DB-9 remote power inhibit and chassis health monitoring interface
• Extended operating temperature range 0 °C to +55 °C, full power without derating for all populated slots
• Supports 3U PXI, PXIe and CompactPCI Express modules
• Compliant with PXI‑5 specification, works seamlessly with NI LabVIEW, TestStand and instrument drivers

Application Scenarios

• 5G NR, Wi‑Fi 7, UWB and broadband wireless test systems with PXIe‑5842 VST
• Aerospace radar, electronic warfare, SATCOM and phased array MIMO validation
• Semiconductor RF SoC, transceiver and power amplifier production ATE test stations
• High-speed streaming, large-channel data acquisition and FPGA-based real-time processing
• Multi-module phase-coherent synchronized measurement systems
• Lab R&D test benches and legacy PXI/PXIe test system upgrade and spare replacement

FAQ

Q1: How many slots and what slot types does PXIe-1075 have?

A1: 18 slots total, including system slot, timing slot, 9 PXIe slots and 8 hybrid slots compatible with legacy PXI modules.

Q2: Can it synchronize multiple VST modules like PXIe‑5842?

A2: Yes, the differential star trigger and SYNC100 bus provide low-skew synchronization for phase-coherent multi-VST MIMO testing.

Q3: Is the power supply hot-swappable?

A3: Yes, the whole power/fan shuttle is a single replaceable unit for fast maintenance.

Q4: Can I use older PXI (non‑Express) modules in it?

A4: Yes, the 8 hybrid slots accept traditional PXI 3U modules.

Q5: Is this chassis still active or end of life?

A5: It is a mature legacy chassis, mostly supplied as used, surplus and refurbished units for existing test benches.
