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.

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.

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 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.

Pylons are stationary metal Device Under Test support structures designed to minimize measurement signal backscattering.

Their shapes, sizes, and construction specifications are determined by requirements such as maximum DUT size, its mechanical properties, and minimum rotator size.

Our reverberation chamber is particularly suited for immunity testing for EMC measurement and special applications for very high-field strength applications (200V/m - 7000V/m). The paddle system ensures that the widest range of frequencies and particularly low frequency performance is maximized. This system meets testing requirements of the IEC61000-4-21 EMC testing specification.

MVG light duty EL/AZ positioners provide accurate rotation, velocity, and direction with platform sizes up to 12.6 x 12.6 in (320 x 320 mm). Their rugged yet straight-forward construction ensures maximum reliability and trouble-free operation.
