Large horizontal planar scanner systems are the ideal system for measuring large aperture antennas with medium to high gain (>15 dBi) making them suitable for testing larger arrays or reflector antennas that require a zenith orientation for testing. Based on an "H" frame design, they are constructed using two reinforced steel X-rails that support a stiff yet lightweight Y-bridge on precision bearing rails. The high capacity probe stage can accommodate various probes from L- to mmWave bands including any necessary RF equipment, probe extensions, and optional roll and z-stages.

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.
