PXI Module, FlexRIO General

The NI PXI FlexRIO General Modules are high-performance, FPGA-based hardware platforms designed for building custom instruments and application-specific test systems. Based on the PXI Express architecture, these modules provide powerful reconfigurable processing, high-bandwidth data movement, and deterministic timing for advanced measurement, control, and signal processing tasks. FlexRIO General modules serve as a flexible foundation that can be paired with FlexRIO adapter modules or used for direct FPGA-centric development. Engineers can implement custom algorithms, real-time processing pipelines, protocol handling, and hardware-timed control directly on the FPGA to achieve performance levels beyond traditional software-defined solutions. NI PXI FlexRIO General Modules are widely used in RF and wireless research, hardware-in-the-loop (HIL) simulation, aerospace and defense systems, semiconductor validation, and advanced R&D environments. Their modular PXI form factor enables scalable, synchronized systems that evolve as application requirements grow.
