Overview

Product overview

Key product information and technical features.

The PXI-8146RT provides the embedded real-time computer function for a PXI system. NI's model-specific explanation distinguishes it from a general-purpose desktop computer: it boots into the real-time operating system and can be accessed using MAX or LabVIEW with the Real-Time Module.

Software selection should follow NI's PXI-814x RT compatibility guidance. NI lists this family among Phar Lap ETS controllers and documents a W2 hardware-jumper requirement for upgrading its real-time software. The listed earliest supported versions do not establish support for every later release.
