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.

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.

The new MVG-Orbit/FR compact, low profile light duty positioners provide accurate, balanced rotation, and controllable velocity in the positioning of light duty antennas under test. Their compact and low-profile design optimizes space in test configurations as well as high operational performance, yielding the best size and weight/performance ratio.

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.

This unique dual-axis positioner is particularly suited for testing direction-sensing antennas. The virtual elevation axis enables rotation of the DUT around its phase center, placing the mechanical support system invariably behind the DUT. This feature maintains the center of the DUT in one place, while eliminating scattering and interference from the positioning structure.

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.
