The AL-9504-2 Emergency Stop (E-Stop) Unit provides a central connection point for external emergency stop panic buttons and positioner controllers that are located throughout the system. In the event of an emergency stop, the AL-9504-2 will command the appropriate positioner controller to disconnect motor drive power on all axes.

MVG heavy duty azimuth positioners provide accurate rotation, velocity, and direction, with turntable diameters up to 122 in. (3100 mm). Their rugged yet straight-forward construction ensures maximum reliability and trouble-free operation.

The AL-4162 programmable positioner controller offers real-time control of positioning subsystems used in near-field and far-field antenna measurement systems. Typically, it may be configured to drive planar scanners and general purpose far-field positioners that are encoder-based or involve simultaneous motion.

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.

The Performance Series EL/AZ positioners represent the latest generation of multi-axis rotary positioning subsystems. They offer enhanced capabilities and improved performance relative to size, and incorporate new engineering advances.

These positioners provide accurate, balanced rotation, and controllable velocity. Their rugged yet straight-forward construction ensures maximum reliability and trouble-free operation, yielding the best size and weight/performance ratio. Typically, the unit includes the body, precise slew bearings, DC motor, gear reducer, encoder/synchro, and limit switch assemblies. The AUT mounting surface is designed with a threaded mounting hole pattern for ease of use. A Safe/Operate switch is included to ensure safety.

An EMC Chamber with 5 meter test range ensuring EMC compliance testing for Emission and Immunity testing. Ferrite and hybrid pyramidal absorbers are combined in a unique pattern within a SmartShield high performance chamber. Operating at a 5m test distance, this EMC chamber is compliant to CISPR-16-1-4 / ANSI C63.4 with a measurement zone diameter of 2 to 4 meters.
