What is RFmx?

RFmx is a set of interoperable software applications that optimize NI RF instrumentation for general-purpose, cellular, connectivity, and aerospace/defense test applications. RFmx simplifies your signal generation and measurement experience.

Why RFmx?

RFmx streamlines test system development by accelerating setup, measurement, and performance. Soft front panels provide an intuitive interface for connecting to hardware, enabling users to efficiently perform measurements and debug automated tests. Composite measurement functionality and parallelized execution ensure maximum instrument utilization for test time reduction. And with dedicated personalities for conventional spectrum analysis, modulated signals, and standard defined signals (5G New Radio, Wi-Fi, Bluetooth), RFmx is tailored to your application. From design to manufacturing test, RFmx helps you achieve your goals faster.

Key Benefits

  • Comprehensive System—Ensure accurate benchtop results for general purpose and standard defined RF measurements. With RFmx and PXI instrumentation, software and hardware connect for seamless signal generation and analysis.
