Capabilities

The system interfaces with a wide variety of RF equipment and is capable of measuring amplitude and phase patterns from X-band to mmWave frequencies. The systems include NSI-MI Antenna Measurement Software.

The system software runs on a Windows-based measurement workstation and provides automatic setup of scans based on measurement parameters and desired output. Measured data can be processed for far-field or holographic patterns yielding complete characterization of the antenna’s performance. A single data set provides information on antenna gain, side lobe structure, beam pointing and cross polarization.

The systems can be supplied with a variety of options to enhance system performance.
