PXI Module, RF Up/Down Converter

The NI PXI RF Up/Down Converter Modules provide high-performance frequency conversion for RF transmit and receive systems within PXI-based test and measurement platforms. Designed to translate signals between baseband or intermediate frequency (IF) and RF, these modules enable flexible system architectures for advanced wireless and RF applications. Built on the PXI Express architecture, RF up/down converters deliver wide bandwidth, low phase noise, and deterministic timing with tight synchronization to other PXI instruments. This allows precise alignment of RF signals across multi-channel systems and supports complex configurations such as MIMO, beamforming, and multi-band testing. NI PXI RF Up/Down Converter hardware is widely used in wireless communications research, 5G and 6G development, radar prototyping, satellite communications, and spectrum monitoring. The modular PXI form factor enables scalable, repeatable RF test systems that can adapt to evolving standards while maintaining performance and reliability.
