Product Overview
The National Instruments PXIe-8133 is an embedded controller for PXI Express systems. It combines a quad core processor, system memory, internal storage, and common computer interfaces in a single PXI Express module. The controller is installed in a compatible PXI Express chassis and provides the processing platform for PXI Express instruments and data acquisition modules.
The quad core processor supports demanding test applications that combine high speed data acquisition, real time analysis, and data logging. The PXIe-8133 is suitable for automated test, laboratory measurement, industrial monitoring, and research applications that require high throughput and multi threaded processing.
Processing and System Resources
The controller provides a quad core processor and integrated system memory to support multi threaded test software. It includes internal storage for the operating system, drivers, application software, and test data. The additional processing cores help with parallel tasks such as data streaming, analysis, and user interface updates running at the same time.
The controller communicates with PXI Express modules through the chassis backplane. This provides a high bandwidth connection between the controller and installed instruments. The integrated design supports deterministic communication and helps reduce latency between the test application and the measurement hardware.
Computer Interfaces
The PXIe-8133 includes common computer interfaces for displays, peripherals, and networks. These interfaces typically include Ethernet, USB, serial, and display outputs. The exact port configuration depends on the controller version and system setup. These ports allow engineers to connect a monitor, keyboard, mouse, network cable, and other accessories directly to the controller.
The Ethernet connection supports network based communication for remote control, data transfer, and system integration. USB ports support storage devices and instrumentation accessories. Display outputs allow a local user interface for bench top use. These interfaces make the controller usable as a standalone PXI Express computer in a test rack.
Software and PXI Express Integration
The PXIe-8133 is designed to work with NI software and drivers for PXI Express systems. It supports LabVIEW, LabWindows/CVI, Measurement Studio, and other development environments used for test and measurement. The controller can be used with NI-DAQmx, NI-DMM, NI-XNET, and other instrument drivers installed on the system.
The controller integrates with the timing and synchronization resources of the PXI Express chassis. Trigger lines and clocks are available to installed modules, allowing coordinated operation between instruments. The embedded controller can run the full test application, log data, and communicate with enterprise systems through its network interface.
Thermal and Installation Considerations
A quad core controller generates heat and must be installed where the chassis can provide adequate airflow. Engineers should verify the operating temperature range and power requirements for the planned configuration, especially when the chassis contains high power instruments. Slot placement and cable routing should not obstruct the controller cooling path.
Stable power and a clean ground reference help maintain reliable operation. The controller should be shut down properly before removal, and software should be configured to save data safely in the event of a power interruption. These practices reduce the risk of data loss and hardware stress.
Typical Applications
Embedded control of high performance PXI Express test systems
Automated production test with real time analysis
Laboratory instrument control and data processing
Industrial monitoring and control systems
Multi instrument PXI Express systems with high data rates
Research and development test benches
The PXIe-8133 is a PXI Express embedded controller that combines a quad core processor, memory, storage, and computer interfaces in a single module. Its processing power and PXI Express integration make it a practical controller for demanding automated test systems.
