The National Instruments PXIe-8398 is a MXI Express module for connecting a PXI Express chassis to a host computer. It provides a high speed remote control link that separates the measurement hardware from the computing platform. The module is used in automated test, laboratory measurement, and industrial systems where the PXI chassis must be located near the device under test while the computer remains in a control area.

MXI Express technology extends the PCI Express bus over a cable. The PXIe-8398 allows the host computer to control PXI Express modules as if they were installed in the computer. This architecture supports flexible test station layout and centralized computing resources.

High Speed Remote Control

The PXIe-8398 provides a high speed link between the host and the PXI Express chassis. Engineers should verify cable length, link bandwidth, and software configuration. The link should be secure and strain relieved.

Remote control supports separation of the computer from the test hardware. This is useful when the test cell has limited space or harsh conditions. The computer can be upgraded without replacing the PXI chassis.

PXI Express Integration

The module operates in compatible PXI Express chassis and host systems. It uses the PXI Express backplane for module communication. Engineers should verify slot compatibility, power requirements, and cooling.

System documentation should include link settings, cable routing, and host configuration. This helps maintenance and troubleshooting.

Applications

The PXIe-8398 is suited to automated test, laboratory instrumentation, production validation, and research systems. It supports flexible placement of PXI Express hardware and host computers.

Installation and Maintenance

Installation requires inserting the module into a compatible slot and connecting the MXI Express cable. Cables should be routed to avoid strain and interference. The chassis and host should provide adequate cooling.

Maintenance includes checking cable connections, verifying link status, and reviewing software configuration. Documentation helps reliable operation.

Summary

The National Instruments PXIe-8398 MXI Express Module provides a high speed remote control link for PXI Express chassis. It supports separation of measurement hardware from the host computer and flexible test station design. The PXIe-8398 is a practical module for engineers who need remote PXI Express control.
