The National Instruments PXIe-1078 is a nine slot PXI Express chassis designed for modular test and measurement systems. It provides the mechanical structure, power, cooling, and backplane connectivity needed for PXI Express modules. The PXIe-1078 can host a PXI Express controller and a mix of instrument and data acquisition modules.
In a PXI Express system, the chassis is the foundation for module communication and physical integration. The PXIe-1078 provides nine slots and a backplane that supports high speed data transfer and timing. Engineers can build a compact system that combines measurement, switching, signal generation, and control.
Nine Slot PXI Express Architecture
The PXIe-1078 provides nine slots for PXI Express and compatible modules. One slot is used for a system controller, and the remaining slots accept instrument or DAQ modules. This configuration supports a controller plus several measurement and control functions.
Modules can include digitizers, signal generators, source measure units, switches, digital I O, and data acquisition cards. Engineers should verify slot compatibility, power requirements, and cooling needs.
Power Cooling and Backplane
The chassis 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.
Applications
The PXIe-1078 is suitable for automated test, laboratory instrumentation, signal analysis, production validation, and research systems. It supports modular expansion and reconfiguration.
Installation and Maintenance
Installation requires mounting the chassis securely, connecting power, and inserting the controller and 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.
Summary
The National Instruments PXIe-1078 PXI Express Chassis provides a nine slot platform for modular test and measurement systems. It combines PXI Express backplane connectivity, integrated power and cooling, and a compact mainframe format. The PXIe-1078 is a practical chassis for engineers who need PXI Express capability in a focused system configuration.
