Applications

• General Antenna Testing
• Satellite Antenna Testing

Capabilities

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

The system software runs on an Intel 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 Large Vertical Planar Near-Field Measurement Systems can be supplied with a variety of options and can be upgraded to allow for cylindrical or spherical measurements to expand system utility.
