Issue Details

I currently have some of National Instruments Radio Frequency (RF) devices and want to know what is included in the RFmx driver and what requires a separate license?

Solution

RFmx provides signal generation and analysis for general-purpose, connectivity, cellular, and aerospace/defense test applications. The installation of the driver can include any of the software shown below. Everything within this list will require a license except RFmx Waveform Creator, RFmx VNA and RFmx SpecAn.
  

  • RFmx SpecAn.
  • RFmx WLAN.
  • RFmx for Bluetooth® Test.
  • RFmx NR.
  • RFmx LTE.
  • RFmx WCDMA.
  • RFmx TD-SCDMA.
  • RFmx EV-DO.
  • RFmx CDMA2k.
  • RFmx GSM.
  • RFmx Pulse.
  • RFmx VNA
  • RFmx Analysis Only.
  • RFmx Waveform Creator ¹.
  • RFmx Demod².
  • RFmx Noise Figure³.
  • RFmx Phase Noise³.
  • RFmx Power Amplifier³.


Notes:

  • ¹: Without any separate licenses, the RFmx Waveform Creator will only allow the creation of tone signals and have the ability to upload custom user signal data. In order to get access to the RF Cellular and Connectivity Standards and Analog/Digital Modulation which include more advanced features (WLAN, Bluetooth, LTE, AM/FM, etc.), you will need to purchase its respective license. 
  • ²: Since RFmx 20.7, RFmx Demod is available as RFmx Digital Modulation and RFmx Analog Modulation and requires a separate license for analog and digital modulation use cases.
  • ³: RFmx Noise Figure and RFmx Phase Noise require licenses despite they exist under RFmx SpecAn. Similarly, since RFmx 20.7, RFmx Power Amplifier (for DPD, AMPM, Programmatic CFR, PxdB Compression measurements​) requires a separate license too.

Additional Information

With RFmx Waveform Creator, RFmx Development licenses grants the ability to save your waveform file and generate the waveform directly from RFmx Waveform Creator. The RFmx Deployment + Debug licenses grant you the ability to generate the waveform directly from RFmx Waveform Creator (via Debug license), but does not have the ability to save the waveform file.
