NSI-500H-15x15水平平面近场量测系统
The 500H-15x15 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. The500H-15x15 is based on an “H” frame design and is constructed using two reinforced steel X rails that supporta stiff yet light weight Y-bridge on precision bearing rails. The high capacity probe stage can accommodatevarious probes from L to mmWave bands including any necessary RF equipment, probe extensions andoptional roll and Z stages.
The system interfaces with a wide variety of RF equipment and is capable of measuring amplitude and phasepatterns from L-band to mmWave bands.
The system includes NSI Antenna Measurement Software. Thesystem software runs on a Windows based measurement workstation and provides automatic setup of scansbased on measurement parameters and desired output. Measured data can be processed for far-field orholographic patterns yielding complete characterization of the antenna’s beam pointing and cross polarization.
The model 500H-15x15 can be supplied with a variety of options including an AUT laser alignment system.
