Description

The Spherical Near-Field Arch Roll Scanner is an ideal system for measuring radiation characteristics of non-moving antennas which require a full hemisphere coverage and can not be tested using the planar near field technique. A traditional spherical near-field system would require the antenna to either move in one or two axes, however the NSI-MI scanner uses a novel dual-axis probe motion design to allow the antenna to remain stationary which is ideal for satellite or radar antenna testing. The system interfaces with a wide variety of NSI, Keysight, or Rohde & Schwarz RF equipment. The Antenna Measurement 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.
