NSI has developed a high precision articulated swing arm system for millimeter wave spherical near-field measurements. This paper presents this system along with structural analysis and characterization, and explains what error corrections are performed in order to produce high accuracy results. Both simulated and measurements are shown to demonstrate the effectiveness of these correction measures.
