The National Instruments PXIe-1065 is an 18 slot PXI Express chassis designed for large modular test and measurement systems. It provides the mechanical structure, power, cooling, and backplane connectivity needed for PXI Express modules. The PXIe-1065 can host a PXI Express controller and a large 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-1065 provides 18 slots and a backplane that supports high speed data transfer and timing. Engineers can build a complete system that combines measurement, switching, signal generation, and control in one mainframe.
Eighteen Slot PXI Express Architecture
The PXIe-1065 provides 18 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 many 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 when configuring the system.
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-1065 is suitable for automated test, laboratory instrumentation, signal analysis, production validation, and research systems. It supports large systems that need many PXI Express instruments in one chassis.
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-1065 PXI Express Chassis provides an 18 slot platform for large modular test and measurement systems. It combines PXI Express backplane connectivity, integrated power and cooling, and a high capacity mainframe format. The PXIe-1065 is a practical chassis for engineers who need many PXI Express instruments in one system.
