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.
