Description
NI PXIe-1082 | 8-Slot PXI Express Chassis 7 GB/s Bandwidth
Dynamic Product Introduction
Field engineers managing automated test rigs know how catastrophic a central mainframe failure can be for production throughput. When a master chassis experiences power rail degradation or backplane communication drops, replacing the core housing quickly without altering existing card arrangements or racking dimensions becomes a top priority.
The NI PXIe-1082 offers a robust 8-slot enclosure engineered for high-throughput instrumentation and data streaming. Combining 7 GB/s overall system bandwidth with 6 hybrid peripheral slots, the chassis accepts standard PXI Express modules, CompactPCI Express boards, and legacy PXI modules. Driven by a quiet variable-speed cooling system and an integrated 584 W power supply, the PXIe-1082 delivers stable system timing via its onboard 10 MHz and 100 MHz reference clock architecture, making it a critical foundation for automated semiconductor test, RF signal analysis, and aerospace simulation setups.

Global Sourcing & Live-Test SOP (Transparency Core)
Sourcing surplus or replacement PXIe mainframes requires thorough physical and electrical verification to guarantee long-term stability under heavy instrument loads.
Inbound Verification & Traceability
- Paperwork Audit: Validation of serial numbers against OEM manufacturing logs to confirm chassis generation and revision history.
- Physical Inspection: Comprehensive check of backplane slot pins, controller card guide rails, fan assembly blades, and power switch mechanics.
Live Rack Simulation & Diagnostics
- Power Rail Stability Check: Multimeter monitoring of +3.3 V, +5 V, +12 V, and -12 V DC power rails under full load to confirm voltage ripple remains well within factory tolerance.
- Backplane Throughput & Clock Testing: Loaded with an embedded PXIe controller and high-bandwidth DAQ cards to run PCIe bus throughput tests and verify 10 MHz / 100 MHz reference clock phase-noise stability on an oscilloscope.
- Cooling System Burn-In: Continuous 24-hour thermal chamber stress test running maximum slot power draw to verify fan auto-throttling and thermal sensor feedback.
Final Prep
- Firmware Checks: Verification of chassis management firmware and EEPROM settings.
- ESD Safe Handling & Shipping: Packaged in heavy-duty anti-static foam wrap and double-walled freight boxes to prevent backplane pin damage during transit.
The Field Engineer’s Pitfall Guide
- ❗ Slot Type & Module Compatibility: While 6 of the slots on the PXIe-1082 are hybrid peripheral slots that support standard PXI cards, legacy 32-bit PXI modules with a backplane J2 connector will not physically fit into hybrid slots without removing or altering pins. Always verify your card connector types before inserting older hardware.
- ❗ Power Budget & Slot Cooling: Exceeding 38 W per slot on continuous high-power RF or FPGA modules without setting the chassis fan speed switch to “High” can trigger thermal shutdowns. In rack installations, leave at least 1U of ventilation space above and below the chassis for adequate airflow.
- ❗ System Timing & Synchronization Routing: When configuring multi-card clock synchronization using the slot 1 system timing capabilities, verify that your software application explicitly maps the PXIe_CLK100 or PXI_CLK10 lines in Measurement & Automation Explorer (MAX) to avoid phase misalignment across instrument channels.
Intent-Driven FAQ
Will swapping out my damaged PXIe-1082 require reconfiguring my software applications?
No. The chassis itself is transparent to your host operating system and LabVIEW applications. As long as you transfer your embedded controller and peripheral cards into the exact same relative slot positions, MAX will recognize the hardware configuration automatically.
Can I use legacy 32-bit PXI cards in the PXIe-1082?
Yes. The PXIe-1082 features 6 hybrid peripheral slots that accept both PXI Express modules and PXI modules equipped with CompactPCI/PXI connectors (such as those without the J2 backplane connector).
What is the power capacity of the built-in power supply?
The chassis includes an integrated 584 W power supply designed to provide clean, regulated DC power across all 8 slots simultaneously under heavy continuous workloads.
How does the variable-speed fan control work on the PXIe-1082?
The chassis features an Auto/High switch on the rear panel. In Auto mode, onboard thermal sensors adjust fan speed dynamically based on ambient intake air temperature to minimize acoustic noise. In High mode, fans run at maximum speed for high-density, elevated-temperature environments.
What warranty is provided on replacement chassis units?
Verified PXIe-1082 chassis units sourced through certified procurement channels include a standard 12-month full-replacement warranty covering backplane connectivity, power supply stability, and fan assembly performance.
