1. Key Product Specifications
The PXIe-1073 balances performance and portability. Below are the primary technical parameters:
| Feature | Specification |
| Total Slots | 5 slots (3 PXI Express, 2 PXI Express Hybrid slots) |
| Bandwidth | Up to 250 MB/s per-slot dedicated bandwidth |
| System Bandwidth | 250 MB/s total system bandwidth |
| Integrated Controller | Built-in MXI-Express controller (x1 link) |
| Power Supply | Integrated AC power supply (approx. 300W total) |
| Cooling | Forced-air cooling with high-performance fans |
| Weight | ~5.8 kg (12.8 lbs) |
2. Product Advantages
Integrated Connectivity: Unlike other chassis that require a separate controller module in Slot 1, the PXIe-1073 has an integrated MXI-Express remote controller. This saves a slot and reduces the initial cost of the system.
Hybrid Slot Capability: It features two hybrid slots, allowing you to use both modern PXI Express modules and legacy PXI modules in the same chassis.
Compact Form Factor: Its small footprint and lightweight design make it ideal for benchtop testing or portable "lunchbox" style test systems.
Acoustic Quietness: Designed with optimized cooling that manages fan noise effectively, making it suitable for laboratory environments.
3. Product Applications
The NI PXIe-1073 is widely used in industries requiring high-speed data acquisition but with a lower channel count than large-scale industrial racks.
Automated Production Testing: Compact enough to fit into manufacturing lines for functional testing of electronic components.
Data Acquisition (DAQ): High-speed streaming for vibration, acoustic, or structural health monitoring.
RF and Wireless Testing: When paired with RF modules, it serves as a compact platform for signal analysis.
Academic Research: A cost-effective entry point for university labs needing PXI Express performance.
4. Important Considerations & Precautions
To ensure the longevity and accuracy of your system, keep the following in mind:
Host Interface: You must have a compatible PCIe-to-MXI card installed in your desktop or a Thunderbolt-to-MXI adapter for laptops to communicate with the chassis.
Cooling Clearance: Ensure at least 76.2 mm (3 in.) of clearance at the back and sides of the chassis for proper airflow. Blocking the fans can lead to thermal shutdown or module damage.
Power Budget: While the 300W power supply is robust, always calculate the total power consumption of your specific modules to ensure they do not exceed the per-slot current limits.
Standard Maintenance: Regularly clean the fan filters to prevent dust buildup, especially in industrial environments.
5. Summary
The NI PXIe-1073 is a "value-performance" chassis. It provides the high-speed backplane of PXI Express with the convenience of a built-in remote controller, making it a "plug-and-play" solution for engineers transitioning from traditional instrumentation to modular PXI systems.
