The National Instruments PXIe-1073 is a five slot PXI Express chassis with an integrated MXI-Express controller. It is designed for compact modular test and measurement systems. The chassis provides power, cooling, and backplane connectivity for PXI Express modules and includes a remote control link to a host computer.
In a PXI Express system, the chassis is the foundation for module communication and physical integration. The PXIe-1073 provides five slots and an integrated MXI-Express interface. Engineers can place the chassis near the device under test while the host computer remains in a control area. This architecture supports flexible test station layout and centralized computing.
Five Slot PXI Express Architecture
The PXIe-1073 provides five slots for PXI Express and compatible modules. The integrated controller occupies the system slot function and provides the link to the host. The remaining slots accept instrument or DAQ modules. This configuration supports a focused set of measurement and control functions.
Modules can include digitizers, signal generators, switches, digital I O, and data acquisition cards. Engineers should verify slot compatibility, power requirements, and cooling needs when configuring the system. A clear module plan helps ensure stable operation.
Integrated MXI-Express Control
The chassis includes an integrated MXI-Express controller for remote host connection. MXI-Express extends the PCI Express bus over a cable. The host computer can control PXI Express modules as if they were installed in the computer.
Remote control supports separation of the measurement hardware from the computing platform. Engineers should plan cable routing, link bandwidth, and software configuration. The link should be secure and strain relieved. Documentation of host and chassis settings helps maintenance.
Power Cooling and Backplane
The PXIe-1073 includes integrated power and cooling for installed modules. Proper airflow is important because PXI Express modules can generate heat during high speed operation. Engineers should keep vents unobstructed and follow installation guidelines.
Power budgeting is part of system planning. Each module has power requirements, and the total load must remain within the chassis capability. Documentation of module power and slot assignment helps prevent issues.
Timing and Triggering
The PXI Express backplane provides timing and triggering resources for module synchronization. Engineers can use trigger lines and clocks to coordinate measurements across multiple instruments. This is important when acquiring correlated data.
Timing configuration depends on the modules and application requirements. The chassis provides the infrastructure, and software configuration defines the behavior.
Applications
The PXIe-1073 is suitable for automated test, laboratory instrumentation, signal analysis, production validation, and research systems. It supports compact systems that need PXI Express capability and remote host control.
Installation and Maintenance
Installation requires mounting the chassis securely, connecting power and the MXI-Express cable, and inserting modules according to the slot configuration. Cable management should allow access to connectors. The chassis should be placed where airflow is not blocked.
Maintenance includes cleaning vents, checking fan operation, inspecting module seating, and verifying power and communication status. Documentation helps reliable operation.
Summary
The National Instruments PXIe-1073 PXI Express Chassis provides five slots and integrated MXI-Express control for modular test and measurement systems. It supports remote host connection, PXI Express module integration, and compact system design. The PXIe-1073 is a practical chassis for automated test and laboratory applications.
