NSI-600C-5
The 600C-5 is a complete cylindrical near-field system ideal for measuring broad beam (azimuth) antennas withapertures less than five feet making it ideal for testing stacked linear arrays. The 600C-5 consists of a verticalprobe tower with an 5’ (1.5 m) travel, high capacity stepper motor based azimuth positioner, control computer,software and cabling. The high capacity probe carriage can accommodate probes as low as S-band includingoptional roll and translation stages. This simple design is easy to assemble and align, accurate, and can bedismantled for transport or storage within one working day.
The system interfaces with a wide variety of RF equipment and is capable of measuring amplitude and phasepatterns from S-band to mmWave Bands. The system includes NSI Antenna Measurement Software.
The system software runs on a Pentium based measurement controller and provides automatic setup ofscans based on measurement parameters and desired output. Measured data can be processed for far-fieldor holographic patterns yielding complete characterization of the antenna’s performance. A single data setprovides information on antenna gain, side lobe structure, beam pointing and cross polarization.
The Model 600C-5 can be supplied with a variety of options to enhance system performance.
