Description
Key Technical Specifications:
  • Processor Options:
    • Dual-Core: Intel Core i5-4400E — 2.7 GHz base, 3.3 GHz Turbo, 2 cores / 4 threads
    • Quad-Core: Intel Core i7-5700EQ — 2.6 GHz base, 3.2 GHz Turbo, 4 cores / 8 threads
  • Memory:​ 2 GB or 8 GB DDR3L-1600 SO-DIMM (1 slot, expandable to 16 GB on some configs)
  • Storage:​ 250 GB or 320 GB 2.5″ SATA HDD (SSD upgrade available); some versions support mSATA
  • PXIe Bandwidth:​ x4 PCIe Gen 2 to backplane — up to 3.2 GB/s system bandwidth
  • Front Panel I/O:
    • 2 × USB 3.0
    • 4 × USB 2.0
    • 2 × Gigabit Ethernet
    • 1 × RS-232 (D-sub 9)
    • 1 × DisplayPort (supports dual-display via DP or DP-to-DVI/VGA adapter)
  • Watchdog Timer:​ Yes — configurable timeout & action
  • OS Support:​ Windows 7/10 (64-bit), NI Linux Real-Time, Legacy PharLap ETS (check part number suffix)
  • Slot:​ PXIe Slot 1 (3U single-width)
  • Operating Temp:​ 0°C to +55°C
  • Power:​ Via PXI chassis backplane
Feature Differences vs PXIe-8135:​ PXIe-8840 is typically a later-generation controller (Haswell/Broadwell vs Ivy Bridge) with improved graphics integration and USB 3.0 native; PXIe-8135 (i7-3610QE) is older but still quad-core — performance comparable in many DAQ tasks; choose based on OS compatibility & chassis slot availability.
Applications:​ Production test, validation labs, mixed-signal data acquisition, university research labs, portable PXI test carts.
Installation & Notes:​ Same as PXIe-8135 — install in Slot 1. Use NI MAX for identification. For Linux RT targets ensure correct kernel/RT image version matches controller generation. Ground chassis properly to minimize EMI on sensitive analog measurements.
