PXI Module, RF Baseband Digitizer

The NI PXI RF Baseband Digitizer Modules provide high-performance digitization of baseband and intermediate frequency (IF) signals for advanced wireless test, measurement, and research applications. Designed to capture complex I/Q data with high fidelity, these modules enable precise analysis of modern communication signals within PXI-based systems. Built on the PXI Express architecture, PXI RF baseband digitizers deliver high bandwidth, low noise, and deterministic timing with tight synchronization to other PXI instruments. Their architecture supports accurate sampling of wideband baseband signals and seamless integration with RF upconverters, downconverters, and transceivers in complete RF test setups. NI PXI RF Baseband Digitizer Modules are widely used in 5G and 6G development, wireless standards validation, radar and electronic warfare prototyping, satellite communications, and advanced RF research. The modular PXI form factor enables scalable, repeatable receive architectures that adapt to evolving wireless technologies while maintaining measurement accuracy and reliability.
