PXI Module, RIO Digitizer

The NI PXI RIO Digitizer Modules provide high-speed, high-resolution signal digitization combined with FPGA-based processing for advanced test, measurement, and research applications. Designed to integrate with NI RIO and FlexRIO FPGA technology, these modules enable deterministic, low-latency acquisition and real-time signal processing within PXI systems. Built on the PXI Express architecture, RIO Digitizer modules deliver high-bandwidth data streaming and precise synchronization with other PXI instruments. Their programmable FPGA resources allow engineers to implement custom triggering, filtering, data reduction, and decision-making directly in hardware, making them ideal for applications that require precise timing and real-time response. NI PXI RIO Digitizer hardware is widely used in wireless communications research, radar and electronic warfare systems, high-speed electronics testing, and hardware-in-the-loop (HIL) simulation. The modular PXI form factor provides scalability and repeatability, enabling systems to evolve as measurement and processing requirements change.
