Spherical Near-Field Vertical Arch Measurement System
Description
Model: SNF-ARCV-2.4NSI-MI Technologies' Spherical Near-Field Vertical Arch Measurement System, SNF-ARCV-2.4, is an ideal solution for measuring radiation characteristics of non-moving antennas that do not require full spherical coverage and cannot be tested using the planar near-field technique. Three axes of motion revolve around the stationary AUT and an arch frame continuously rotates in the phi axis at speeds up to 5 revolutions per minute. The theta axis carriage carries the measurement probe through 115 degrees of travel along the arch frame, with a linear slide providing precise real time radial adjustment. Proprietary error correction technique is used to further enhance its global accuracy. The versatile system is suitable for advanced phased array and general purpose antenna testing.
