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.

ULTRA UHC series polypropylene based broadband electromagnetic absorbers are the latest technology for RF test applications.

The polypropylene material has a highly uniform carbon density, throughout the material, which provides for more predictable results with no discontinuities.

It is the unique production technology which is the critical factor in achieving the highest electromagnetic reflectivity performance in an antenna measurement anechoic chamber or an emc chamber.

As an international EMC chamber supplier, we provide these polypropylene broadband absorbers for EMC test chambers worldwide.

These MVG-Orbit/FR Legacy Series EL/AZ Positioners provide accurate, balanced rotation, and controllable velocity of 2 axes, for the positioning of very large devices in test configurations.

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, a DC motor, gear reducer, encoder/synchro, and limit switch assembly. The turntable surface is designed with a threaded mounting hole pattern for ease of use. A Safe/Operate switch is included to ensure safety.

The EH022 EMC Horn combines stable gain performance and low VSWR with wide band frequency operation. The horn is single linearly polarized with excellent cross-polar discrimination. The unique horn design suppresses any possible excitation of higher order modes in the aperture and maintains a well-defined smooth radiation pattern in the direction of the boresight axis throughout the operational bandwidth.

Aperture field probe systems are used to evaluate the extraneous signals that exist in the area surrounding the device under test due to reflections and other transmitting sources.

MVG offers a complete range of field probes of varying sizes and configurations to meet diverse testing requirements.
