More Product Information
Specific application to Automotive.
The Gold standard for EMC Anechoic Chambers, this 10 meter test range ensures EMC compliance testing Emission and Immunity testing and is compliant to ANSI C63.4/CISPR-16-1-4 with a Test Volume diameter of 4 meters or greater. The most versatile and accurate of EMC test chambers. Ferrite tiles and hybrid pyramidal absorbers allow for high accuracy and performance while meeting compact space requirements.
The CISPR25 emc chamber is designed for emc compliance benchtop testing of automotive components and wiring harnesses . The MVG CISPR25 emc chamber is designed for the emc measurements using the requisite 1 m test distance and for a “typical bench” configuration of 2.5 m x 1.0 m. The unique design requires less volumetric space than traditional absorbers and still provides the volume required to have the requisite distances between the EUT and the walls and the emc absorber and the walls & ceiling. The chamber is designed with anechoic treatment that meets the specified attenuation in the CISPR 25 standard, and it is designed to meet the Long Wire testing specified in Annex J. The polypropylene emc absorber does not undergo the typical age-related deterioration of the typical “foam” polyurethane absorbers. The UH-series, polypropylene emc absorber is also applicable to the radar pulse testing required in some automotive test standards.
Cryogenic Temperatures
- Fully isolated experiment space for true 4K temperatures during probing
- Cryogenic positioners to provide large travel ranges without warming up the device
- Integrated helium pot for high temperature stability of the device under test
- Fully dry cryogen-free cooler eliminates the need for expensive helium circulation systems
- Rapid cool liquid nitrogen option for faster cool down times

The AL-4164 and AL-4166 programmable controllers offer real-time control of positioning subsystems used in near-field and far-field antenna measurement systems. They may be configured to drive planar scanners and general purpose far-field positioners that are encoder-based or involve simultaneous motion.
The EH1840 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.
The AL-48060 series controllers drive up to 6 axes sequentially. These popular, programmable controllers provide manual front panel control or remote control of rotary and linear positioners. Optional interfaces are available for position transducers such as absolute encoders, Inductosyn®, and inclinometers.
A Semi Anechoic EMC Chamber with 3-meter test range ensuring EMC compliance for Emission and Immunity testing. Ferrite and hybrid pyramidal EMC absorbers are combined in a unique pattern within a SmartShield high performance chamber. Operating at a 3m test distance, this chamber is compliant to ANSI C63.4/CISPR-16-1-4 with a Test Volume diameter of 1 to 2 meters.
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.
