Implementation of a 22' x 22' Planar Near-Field System for Satellite Antenna Measurements
Author: Greg Hindman, Greg Masters
Design and implementation of a large horizontal planar near-field system delivered to Space Systems / Loral for satellite antenna testing will be discussed. The 22' by 22' scan plane is 25' above the ground and employs real-time optical compensation for the X,Y, and Z corrections to the probe position. The system provides high-speed multiplexed near-field measurements using NSI's software and the HP-8530A microwave receiver. System throughput is enhanced through the use of a powerful and flexible test sequencer software module.
