NSI-300V-12x9垂直平面近場量測系統
The 300V-12x9 is an ideal system for measuring medium and high gain antennas (>15 dBi) with medium sized apertures making it suitable for testing medium arrays or reflector antennas. The 300V-12x9 is based on an inverted “T” design and is constructed of steel. For high stability a welded cross-braced dual-rail base is used.
This robust design is easy to maintain and align, and highly accurate. Disassembly can be completed in one day. The high capacity probe carriage accommodates probes as low as L-band including 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 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 lobes structure, beam pointing and cross polarization.
The 300V-12x9 can be supplied with a variety of options and can be upgraded to allow for cylindrical or spherical measurements to expand system utility.
