RF Shielded Testing Enclosures, We have the right one for You!Randy Mitchell (VTech)
RF Shielded Testing Enclosures-what are they?
RF Shielded EMC Testing Enclosures are based on the theory of the “Faraday Cage”, pioneered by Michael Faraday in 1836. A Faraday Cage is made of a conductive metal mesh or solid conductive metal plates that will not allow external electric fields to enter the area that the cage encloses. Our RF Shielded EMC Testing Enclosures are made of metalized conductive textiles, making them easy to assemble, lightweight and portable.
RF Shielded Testing Enclosures-what are they used for?
An RF Shielded Enclosure is most commonly used to produce an “RF ambient free environment”, meaning that the only electronic field inside the enclosure is caused by the device inside it. This environment is IDEAL for the ElectroMagnetic Compliance (EMC) testing of electronic devices/components that emit RF signals. The devices must pass tests to be compliant with applicable ElectroMagnetic Compatibility (EMC) Standards in order to be approved for sale and distribution. These standards differ depending on where and what the product is used in. Many companies recognize the fact that they should be compliant with all of the standards, as they work in a “global market” and will be selling their products worldwide. Some of the standards are:
- SAE (Society of Automotive Engineers)
- MIL-STD (US Military Standard)
- CISPR (Comite International Special des Perturbations Radioelectriques)
- ISO (International Organization for Standardization)
- IEC (International Electrotechnical Commission)
- EN (European Standard)
What do the EMC tests involve?
The tests involve three issues:
- RF Emissions– These tests determine if the Device Under Testing (DUT) is only emitting RF noise within the limits of the applicable standard. If the device is emitting RF noise above the level allowed, an RF Shielding Solution must be applied to make the device come into compliance with the standard.
- RF Susceptibility– These tests determine if the DUT is susceptible to interference by RF noise allowed in its working environment. If the device is susceptible to interference, again an RF Shielding Solution must be applied to allow the device to work up to its potential.
- RF Immunity– These tests determine if the DUT can function at full capacity in an RF environment up to the level of the standard. If the device is not affected by RF Radiation up to the standard, the device is considered “immune” and meets the standard.
How are RF Shielded EMC Enclosures available?
RF Shielded EMC Testing Enclosures come in several “standard sizes”, but most of VTT’s Enclosures are built to the customer’s specific needs in size, Shielding Effectiveness (SE), and custom options! Here is a video that shows a variety of our enclosures!
