NI PXIE-1065
Product Introduction
The NI PXIe-1065 is a high-performance 8-slot PXI Express chassis developed by National Instruments (NI), serving as the foundational platform for modular test, measurement, and automation systems. As a key member of NI’s PXIe chassis family, it combines flexible slot configuration with robust timing and synchronization capabilities, making it ideal for integrating mixed-signal modules (e.g., data acquisition, signal generation, and control) in industrial and laboratory environments.
At the heart of the NI PXIe-1065 is its hybrid backplane design: 1 dedicated system timing slot (for PXIe controllers) and 7 hybrid slots that support both PXIe and legacy PXI/CompactPCI modules. This backward compatibility protects existing investments while enabling upgrades to high-speed PXIe technology. Paired with NI PXIe controllers (such as the NI PXIe-8880) and application-specific modules, the NI PXIe-1065 delivers a scalable solution—engineers can start with a basic 2-module setup and expand to 8 modules as test requirements grow, eliminating the need for full system overhauls.
Core Advantages and Technical Highlights
High-Speed Data Throughput: The NI PXIe-1065 features a PXIe backplane with 8 GB/s total system bandwidth, ensuring fast data transfer between modules and the controller. Each hybrid slot provides 1 GB/s of dedicated bandwidth (via x1 PXIe lane), which is 10x faster than traditional PXI chassis. This speed is critical for high-throughput applications like real-time signal processing or multi-module test systems, where delays can compromise data accuracy.
Flexible Module Compatibility: Unlike chassis limited to only PXIe modules, the NI PXIe-1065’s 7 hybrid slots work with PXIe, PXI, and CompactPCI modules. For example, users can pair a PXIe data acquisition module (e.g., NI PXIe-4497) with a legacy PXI signal generator in the same NI PXIe-1065 chassis, avoiding the cost of replacing existing hardware. This flexibility makes it a versatile choice for mixed-technology environments.
Reliable Timing and Synchronization: The NI PXIe-1065 includes an integrated 10 MHz reference clock and supports PXIe’s native synchronization buses (Trigger Bus, Star Trigger, Sync Bus). This ensures sub-nanosecond timing alignment across all modules—essential for applications like phase-coherent measurements or multi-channel test setups. For instance, in radar system testing, the NI PXIe-1065 synchronizes multiple receiver modules to capture time-aligned data from different antenna elements, enabling accurate target detection analysis.
Temperature-Controlled Cooling: The chassis uses 3 variable-speed fans with front-to-back airflow, which adjust speed based on internal temperature. This design prevents overheating (a common cause of module failure) while reducing noise during low-load operation. The front-to-back airflow also aligns with data center cooling standards, making the NI PXIe-1065 suitable for rack-mounted industrial systems.
Typical Application Scenarios
The NI PXIe-1065 is widely used in industrial test and automation projects that require modularity and performance. In semiconductor manufacturing, it serves as the core of integrated circuit (IC) test systems: engineers install NI PXIe-1065 in test racks, pairing it with PXIe digital I/O modules (for IC pin stimulation) and PXIe oscilloscope modules (for signal measurement). The chassis’ synchronization capabilities ensure that test signals and measurements are time-aligned, enabling accurate validation of IC performance before shipment.
In automotive electronics testing, the NI PXIe-1065 supports end-of-line (EOL) test stations for components like infotainment systems or ADAS (Advanced Driver Assistance Systems). Technicians connect multiple modules to the NI PXIe-1065—such as a PXIe audio analyzer (for infotainment testing) and a PXI CAN/LIN interface module (for ADAS communication testing). The chassis’ compact size (5.25 in height) allows it to fit in space-constrained production lines, while its high bandwidth handles the large volume of test data generated.
In aerospace and defense, the NI PXIe-1065 is used in avionics test benches to validate flight control systems. It integrates PXIe data acquisition modules (for sensor signal capture) and PXIe communication modules (for simulating aircraft bus protocols like ARINC 429). The NI PXIe-1065’s rugged design (operating temperature 0–55 °C) and reliable cooling ensure consistent performance in harsh lab or field environments, critical for meeting strict aerospace safety standards.

Installation, Commissioning and Maintenance Instructions
Installation preparation: Before installing the NI PXIe-1065, ensure the installation area has adequate ventilation (minimum 10 cm clearance around the chassis) and a stable AC power source (100–240 VAC). For rack mounting, use NI’s optional rack ears (part number 781548-01) and ensure the rack can support the chassis’ 7.3 kg weight. Power off the chassis and all connected modules before installation. Insert modules firmly into the desired slots (aligning with the backplane connector) until the module’s front panel is seated; secure each module with screws to prevent movement. Connect the chassis to a PXIe controller (e.g., NI PXIe-8880) via the system timing slot (Slot 1), then power on the chassis and install the latest NI-DAQmx or NI-VISA drivers for full module compatibility.
Maintenance suggestions: For long-term reliability of the NI PXIe-1065, clean the front air filter monthly with compressed air (or replace it every 6 months, part number 781549-01) to prevent dust buildup, which can block airflow and cause overheating. Inspect the backplane connectors quarterly for corrosion or debris; clean gently with a dry, lint-free swab if needed. If the chassis’ fan warning light illuminates, check for blocked vents or a failed fan—replace faulty fans with NI-approved spares (part number 781550-01) to avoid overheating. Calibrate the chassis’ timing circuits annually using NI’s Calibration Executive software to maintain synchronization accuracy. For persistent issues (e.g., no power, module communication errors), contact NI technical support—do not disassemble the chassis, as this will void the warranty.
