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 beam pointing and cross polarization. The scanners can be supplied with a variety of options and can be upgraded to allow for vertical planar measurements to expand system capabilities.
