Spherical Measurement Accuracies NSI’s Goal.
Nearfield Systems Inc., (NSI) will introduce its newest spherical antenna measurement system for stationary Antennas Under Test (AUT) at the 2009 Antenna Measurement Techniques Association (AMTA) annual symposium November 1 to 6 in Salt Lake City.
The new NSI-700S-400 Spherical Near-Field Arch Roll Scanner, together with NSI’s Panther 9000 RF subsystem and NSI 2000 antenna test and measurement software, provides spherical measurement accuracies of AUTs rivaling those currently obtained only with planar scanning techniques. The new NSI-700S-400 scanner, unlike traditional Spherical Near-Field systems that require one or two axes of the AUT to move, uses an innovative probe motion design to capture measurements of stationary antennas. The new NSI scanner is ideally suited for precision testing of satellite or radar antennas that demands a fixed position throughout the testing process.
