NI PXIE-1085
2. Product Introduction
The NI PXIE-1085 is a high-performance 18-slot PXIe chassis, serving as the backbone for modular test and measurement systems. It combines the flexibility of PXIe (PCI eXtensions for Instrumentation Express) with backward compatibility for PXI modules, making it an ideal platform for building scalable and high-performance test systems.
With 1 System Timing Slot and 17 Hybrid Slots, the PXIE-1085 can accommodate a wide range of PXIe and PXI modules, from data acquisition and signal generation to switching and control modules. This versatility allows users to configure systems tailored to their specific application needs, whether in aerospace testing, semiconductor validation, or industrial automation.
The chassis features a high-bandwidth backplane with an aggregate bandwidth of up to 24 GB/s, enabling fast data transfer between modules and the system controller. This high bandwidth is crucial for applications involving large data sets, such as high-speed signal acquisition or real-time processing of complex waveforms.
3. Core Advantages and Technical Highlights
High-Bandwidth Backplane
The PXIE-1085’s backplane, with up to 24 GB/s aggregate bandwidth, ensures rapid data transfer between modules and the controller. This is particularly beneficial in applications like high-speed digitization, where large amounts of data need to be transferred from the digitizer module to the controller for processing. For example, in radar signal analysis, the high bandwidth allows for real-time capture and processing of wideband radar signals, enabling accurate target detection and tracking.
Flexible Slot Configuration
With 1 System Timing Slot and 17 Hybrid Slots, the PXIE-1085 offers exceptional flexibility. The System Timing Slot can house a timing and synchronization module (such as the PXIe-6672T) to provide precise clock and trigger signals across the system. The Hybrid Slots support both PXIe and PXI modules, allowing users to integrate existing PXI modules with newer PXIe modules. This backward compatibility protects investment in legacy equipment while enabling upgrades to higher-performance PXIe modules.
Advanced Cooling System
Equipped with 8 hot-swappable, variable-speed fans, the PXIE-1085 maintains optimal operating temperatures for modules even in high-density configurations. The variable-speed fans adjust their speed based on the thermal load, reducing noise when the system is under light load and increasing airflow when temperatures rise. This ensures reliable operation of heat-generating modules, such as high-power signal generators or processors, in extended test runs. The fan-fail detection feature alerts users to fan malfunctions, preventing overheating and potential damage to modules.
Precise Timing and Synchronization
The PXIE-1085 supports a range of timing and synchronization features, including 10 MHz reference clock, 100 MHz system clock, PXIe trigger bus, PXI trigger bus, and star trigger. These features enable tight synchronization between modules, which is essential in applications like multi-channel data acquisition or coordinated signal generation. For instance, in a wireless communication test system, precise synchronization between the signal generator, vector signal analyzer, and switching modules ensures accurate measurement of device performance.
4. Typical Application Scenarios
Aerospace and Defense Testing
In aerospace and defense, the PXIE-1085 is used to build integrated test systems for avionics, radar, and communication equipment. It can house modules such as high-speed digitizers (PXIe-5186), RF signal generators (PXIe-5673), and switching modules (PXIe-2597) to create a comprehensive test platform. The high bandwidth and precise synchronization allow for testing of complex systems, such as satellite communication transceivers, ensuring they meet strict performance requirements.
Semiconductor Test
Semiconductor manufacturers rely on the PXIE-1085 for wafer-level and device-level testing. The chassis can accommodate modules for parametric testing (PXIe-4141), digital I/O (PXIe-6570), and mixed-signal testing (PXIe-6368). The flexible slot configuration allows for easy reconfiguration of the test system to support different device types, while the high bandwidth enables fast data transfer between modules and the controller, reducing test time and increasing throughput.
Industrial Automation
In industrial automation, the PXIE-1085 serves as a control and monitoring platform for manufacturing processes. It can integrate data acquisition modules (PXIe-6361), motion control modules (PXIe-7350), and machine vision modules (PXIe-1435) to monitor and control production lines. The precise timing and synchronization features ensure coordinated operation of different components, improving process efficiency and product quality. For example, in a automotive assembly line, the system can synchronize vision inspection with robotic assembly to ensure accurate part placement.
Research and Development
Research labs use the PXIE-1085 to build custom measurement systems for a wide range of applications, from quantum physics to renewable energy research. The chassis can accommodate specialized modules, such as lock-in amplifiers (PXIe-5610) and waveform generators (PXIe-5450), to support unique experimental setups. The high bandwidth and flexibility allow researchers to quickly adapt the system to changing experimental requirements, accelerating the pace of discovery.

6. Installation, Commissioning and Maintenance Instructions
Installation Preparation
Before installing the PXIE-1085, ensure that the installation location is clean, dry, and well-ventilated. The chassis should be placed on a stable, level surface capable of supporting its weight. Provide adequate clearance around the chassis for airflow—at least 15 cm on all sides. Connect the chassis to a properly grounded AC power source (100-240 VAC, 50-60 Hz).
Module Installation
Power off the PXIE-1085 before installing or removing modules. Use an anti-static wristband to prevent electrostatic discharge (ESD) damage to modules. Align the module with the guide rails in the desired slot and gently insert it until it seats firmly. Secure the module with the front panel screws. Ensure that modules are installed in the correct slots—PXIe modules in PXIe slots and PXI modules in Hybrid Slots.
Commissioning Steps
Power on the PXIE-1085 and launch NI MAX to detect the chassis and installed modules. Configure the chassis settings, such as fan speed and power management, as needed. Run self-tests on the chassis and modules to verify their operation. Calibrate modules according to their specifications using NI calibration software. Test the system with a sample application to ensure that data transfer, timing, and synchronization are working correctly.
Maintenance Suggestions
Regularly inspect the PXIE-1085 for dust accumulation, especially on the fan filters and vents. Clean the fan filters monthly using compressed air or a vacuum cleaner to maintain proper airflow.
