Model 700S-90 is an ideal system for measuring medium and low gain antennas up to 60 inches (1.5 m) in diameter. It is well suited to perform cellular and PCS band base-station antenna testing. The 700S-90 uses a dual-axis theta-over-phi high accuracy stepper motor based positioning system with an adjustable extension arm for the probe. The system can support AUT loads of up to 300 lbs (136 kg). The location of the probe is adjustable to accommodate different configurations.The NSI-700S-90 uses an overhead dielectricly swing-arm for probe motion in the theta axis, and a dielectric AUT support stage for motion in the phi axis. The overall system is specifically designed to eliminate the adverse effects from interactions between the AUT and the surrounding environment. It is the ideal solution for providing complete 3D characterization of the antenna or wireless device.

The system interfaces with a wide variety of RF equipment and is capable of measuring amplitude and phase patterns from 0.5 GHz to 40 GHz.. The Model 700S-90 includes NSI Antenna Measurement Software.

The system 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-90 can be supplied with a variety of options to enhance system performance.
