Overview
The Maturo 3-axis APL positioning system is especially designed for antenna measurements in near-field or far-field.
The Device APL-50kg is especially designed for antenna measurements and tests. Different sized of antennas can be mounted on the rotating plate.
The polarisation positioner is mounted onto the azimuth positioner to have both 360° vertical and horizontal rotation for 3D measurements. The system performs three-dimensional over-the-air radiation measurements.
