The NSI model 700S-200 is an ideal system for measuring radiation characteristics of vehicle mounted antennas. The system interfaces with a wide variety of NSI, Agilent, or R&S RF equipment. The Model 700S- 200 includes NSI’s NSI 2000 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 performance. A single data set provides information on antenna gain, sidelobe structure, beam pointing and cross polarization. The Model 700S-200 can be supplied with a variety of options to enhance system performance.
The 700S-200 consists of a 6.5m (21.3 ft)diameter vehicle turntable and an overhead gantry with scanning radius of 12.5m (41 ft). The rotator can support loads up to 4,500 kg (10,000 lb) and can operate at speeds up to 12 degs/sec. The gantry is a dielectric design to minimize reflections, and is capable of speeds up to 0.5 deg/sec over its travel range of 0 to 90 degrees. At 90 degrees, the gantry is recessed completely below ground level, allowing the turntable to be used for far-field measurements.
