RFmx Noise Figure is a license for the RFmx SpecAn measurement personality that extends the capability of NI RF instrumentation for noise figure analysis. This software enables you to measure noise figure, gain, and effective temperatures using the Y-factor and Cold Source methods. You can improve measurement accuracy with built-in calibration procedures and decrease test time with integrated noise source control and multifrequency measurement optimization. With RFmx, you can perform and debug measurements quickly and easily with interactive software front panels, create and playback open, unlocked waveforms with RFmx Waveform Creator, and speed up automated testing with the performance-optimized API. This software requires RFmx SpecAn to be installed.
