Description
Here’s a detailed overview of the National Instruments (NI) PXIe-8861, a high-performance PXI Express embedded controller designed to manage and automate modular test systems:
Overview & Purpose
The NI PXIe-8861 is an embedded controller for PXI Express (PXIe) chassis, acting as the central processing unit for automated test and measurement systems. It combines industrial computing power with the modularity of PXIe, enabling complex data processing, real-time control, and synchronization of multiple instruments in a single chassis.
Key Features
- Processor: Powered by an Intel Xeon E3-1505L v5 quad-core processor (2.0 GHz base, up to 2.8 GHz turbo), optimized for compute-intensive tasks.
- Memory: Supports up to 32 GB DDR4 RAM (user-configurable).
- Storage: Includes a 500 GB SATA SSD (upgradeable) for OS, software, and data storage.
- Operating System: Preinstalled with Windows 10/11 or NI Linux Real-Time OS (flexible for real-time applications).
- Connectivity:
- Expansion: Supports hybrid systems with PXI and PXIe modules in the same chassis.
Technical Specifications
- Chassis Compatibility: Requires a PXIe chassis with a dedicated system slot (e.g., NI PXIe-1085).
- Cooling: Designed for air-cooled chassis (ensure proper airflow and thermal management).
- Power: Draws power directly from the chassis (no external PSU needed).
- Real-Time Performance:
- Sub-microsecond synchronization via PXI Trigger Lines.
- Optional NI Linux Real-Time OS for deterministic execution.

Common Applications
- Automated Test Systems (ATE): Central control for manufacturing test racks (e.g., semiconductor, aerospace).
- Real-Time Data Processing: High-speed signal analysis, closed-loop control, and hardware-in-the-loop (HIL) simulation.
- Modular Instrumentation: Coordinates multi-device workflows (e.g., combining DMMs, oscilloscopes, and switches).
- Data-Intensive Tasks: Image processing, RF recording, and large-scale data acquisition.
Software & Programming
- LabVIEW Integration: Optimized for developing/test sequencing with NI’s graphical programming tools.
- NI-DAQmx Drivers: Streamlines communication with DAQ modules.
- Third-Party Support: Compatible with Python, C/C++, .NET, and MATLAB via NI’s API layers.
- Real-Time OS: Enables deterministic execution for time-critical applications.
System Integration Tips
- Chassis Selection: Pair with a high-slot-count chassis (e.g., NI PXIe-1095) for scalability.
- Thermal Management: Ensure chassis fans and airflow meet the controller’s thermal requirements.
- Hybrid Backplane: Use PXIe Hybrid slots to support legacy PXI modules.
- Networking: Use Gigabit Ethernet or PCIe MXI-Express for remote control and data transfer.
Troubleshooting
- Boot Failures: Verify OS compatibility and update chassis firmware.
- Overheating: Monitor chassis temperatures and clean airflow filters.
- Driver Conflicts: Ensure NI software (e.g., NI Measurement & Automation Explorer) is updated.
- PCIe Link Errors: Check chassis-controller compatibility and reseat the controller if necessary.
Procurement & Support
- Purchase Options: Available through NI or authorized distributors (e.g., Keylink, Apex Waves).
- Customization: RAM, storage, and OS options can be tailored to application needs.
- Documentation: Refer to the NI PXIe-8861 User Manual for setup and specifications.
The PXIe-8861 is ideal for engineers needing a rugged, high-performance controller to orchestrate complex test systems with precision and scalability. For advanced setups, combine it with NI’s FlexLogger or TestStand for turnkey automation solutions.
