Capabilities
The CRS-PORT-18-0.5 supports NSI-MI and Keysight RF receivers and is capable of measuring amplitude and phase from 18.0 GHz to 110.0 GHz. The system includes a workstation featuring state-of-the-art NSI-MI antenna test software. Measured data provides direct far-field patterns allowing for complete characterization of the antenna’s performance. A single data set provides rapid information on antenna gain, beamwidth, side lobe structure, beam pointing, and cross polarization among other parameters.
