NSI-700S-400球面近场曲面量测系统
The NSI model 700S-400 is an ideal system for measuring radiation characteristics of vehicle mounted antennas. The system interfaces with a wide variety of NSI, Agilent, or Rohde & Schwarz RF equipment. The Model 700S-400 includes NSI’s NSI 2000 Antenna Measurement Software. This software runs on a Windows 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 lobe structure, beam pointing and cross polarization. The Model 700S-400 can be supplied with a variety of options to enhance system performance.
The 700S-400 consists of a vehicle turntable and an overhead mechanical arch with scanning radius of 30 ft (9.1 m). The rotator can support loads up to 35,000 lb (15,900 kg) and can operate at speeds up to 12°/s. The arch is a steel semi-monocoque structure designed for stiffness, providing a solid base for the angular probe movement at up to 1°/s over a 135 degree span.
