    NSI-500H-22x22
 22' x 22' (6.7 m x 6.7 m) Horizontal Planar Near-field Measurement System

DESCRIPTION

The 500H-22x22 is an ideal system for measuring large aperture antennas with medium to high gain (>15 dBi) making it suitable for testing larger arrays or reflector antennas that require a zenith orientation for testing. The 500H-22x22 is based on an "H" frame design and is constructed using two reinforced steel X rails that support a stiff yet light weight 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.
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 Antenna Measurement Software. The system software runs on a Pentium 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 model 500H-22x22 can be supplied with a variety of options and can be upgraded to allow for vertical planar measurements to expand system capabilities.
