Spherical Near-Field VerticalArch Measurement SystemSNF-ARCV-2.4
DESCRIPTIONNSI-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.
TYPICAL APPLICATIONS • Wireless technology• General antenna testing• Satellite antenna testing
FEATURES• Radiation pattern testing of stationary AUT• High positioning accuracy and repeatability• Rotary positioner provides 360° phi rotation of arch• Automatic electronic alignment capability• 3D dynamic on-the-fly probe position correction• Multi-beam, multi-frequency control of RF subsystem• Accurate probe motion from 0–115° in theta

CAPABILITIESThe Spherical Near-Field Vertical Arch Measurement System supports NSI-MI, Keysight, and Rohde & Schwarz RF receivers and is capable of measuring amplitude and phase patterns from low frequency to mmWave. The system includes a software workstation preloaded with NSI2000 antenna measurement software and Windows operating system, providing 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.
