RF Shielded Enclosures-Test with Confidence!

RF Shielded Enclosures-Test with Confidence!  Pre-Compliance EMC Testing requires a low ambient environment for accurate testing.  The only Source of interference in the testing enclosure should be the Device Under Testing (DUT).  RF Shielded enclosures are based on the Faraday Cage Principle which states that electromagnetic fields approach the outside of the enclosure, they will not pass through the walls of the enclosure.  The interior of the testing enclosure should have no ambient RF radiation higher than the level that you are testing for based on the Shielding Effectiveness of the enclosure.  During the testing, any RF radiation higher than the floor level would logically be a product of the DUT.

RF Shielded Enclosures-Test with Confidence!  Emissions Testing determines if the emissions of the DUT are within the acceptable emission standards.  There are different emissions allowances depending on the future use of the electronic device.  If the device doesn’t emit RFI above the acceptable level, the device will pass the emission testing.  On the other hand, if the device emits RFI exceeding the EMC standard, the device will have to be altered to correct the offending emissions, lowering them to within the EMC Standards.

RF Shielded Enclosures-Test with Confidence!  The most common correction excessive emissions is an RF Shielding Solution.  This solution involves using conductive metalized textiles similar to the ones that make up the testing enclosure.   Covering or wrapping the device with these lightweight textiles effectively blocks the release of the offending frequencies of RFI, solving the emission issue.  Pre-Compliance EMC Testing products early and often during development, assisting the development of the product.  Contact VTT to learn more about the ideal RF Shielded Enclosure for your Pre-Compliance EMC Testing needs!
