The mmWave OTA Validation Test Software comprises the following components for interfacing and controlling the mmWave OTA Validation Anechoic Chamber and instrumentation.
Use the mmWave OTA Validation Configurator to configure an OTA sweep and access all the tools needed for your OTA test workflow. The mmWave OTA Validation Configurator creates a configuration file that you can use with TestStand template sequences, C# code, MATLAB® language, or Python code. The mmWave OTA Validation Configurator also integrates the mmWave OTA Validation Visualizer so you can easily view your test results from the same interface.
Use the installed TestStand template sequences to run the configuration files that you create with the mmWave OTA Validation Configurator. The template sequences control all aspects of your OTA test and are open-source to enable customization of your test plan.
Use the mmWave OTA Validation Visualizer to complete offline analysis of the test data for antenna measurements.
Use the mmWave OTA Validation Positioner Control Panel to control the movement of the positioner.
The 3GPP standard for OTA test of 5G NR DUTs requires making power measurements in a spherical grid around the DUT. This process can take a significant amount of time due to the large number of points to test, the movement of the DUT positioner, and coordination with the measurement equipment. NI provides two modes of operation for the positioner: Step-by-Step Position Sweeping and Autonomous Position Sweeping.
Use the OTAMI LabVIEW interface to store your measurements and compute the most common OTA measurements:
Use the LabVIEW plugin interfaces to customize and adapt the mmWave OTA Validation Test Reference Architecture for your testing environment. To enable the highest degree of customization, NI provides the source code for the plugins. The following plugins are installed with the mmWave OTA Validation Test Software.
Use RFmx SpecAn and RFmx NR to control the instrumentation and configure 3GPP 5G NR and spectrum measurements. The mmWave OTA Validation Test Software supports RFmx NR ACP, CHP, EVM, OBW, and SEM measurements. Refer to the RFmx NR Help at ni.com/manuals for more information about NR measurements.
