Rotary Positioners

Performance Series - Virtual EL/AZ/Roll Positioners - Medium Duty

The Virtual EL/AZ/Roll Positioner represents the latest generation of multi-axis rotary positioning medium-duty subsystems. It offers enhanced capabilities and improved performance relative to size and incorporates new engineering advances.

Particularly suited for testing direction-finding antennas, the virtual elevation axis enables rotation of the DUT around its phase center, placing the mechanical support system behind the DUT. This feature maintains the center of the DUT in one place, while eliminating scattering and interference from the positioning structure.
