High Attenuation Portable Tent for Test Labs

High Attenuation RF / EMI Tent Test Enclosure Certified in Independent Testing.

Canandaigua, NY USA:  High RF / EMI attenuation for a Select-A-Shield™ test enclosure has been certified in recent testing.  Results included -98.9 dB average shielding effectiveness (SE) at commonly used cellular and Wi-Fi frequencies. The IEEE® 299 -2006 test was conducted by an independent test lab on a complete system including installed components operating under typical conditions. Collapsible Select-A-Shield High Attenuation RF / EMI Test Enclosures conserve space when not in use and are easy to transport. They are manufactured in the USA by Select Fabricators, Inc.

Minimum shielding performance of -85 dB over a range of frequencies from 30 MHz to 10 GHZ was certified by an independent EMC test lab. This testing and analysis is a significant improvement in qualifying flexible enclosures based on the total system rather than relying only on conductive fabric testing data currently used by others in the industry. For testing purposes, Select Fabricators, Inc. installed necessary components before testing in order to get realistic results rather than relying on the fabric's high conductivity.

The High Attenuation RF and EM shielding test enclosure easily assemblies and disassembles in just over an hour. It can be taken down and stored when not in use, saving valuable lab space. The tent and frame fit into hard shell rolling cases and their lightweight design allows affordable shipping via standard shipping services.  Unlike hard wall enclosures, this portable tent can be used in multiple locations and applications, including remote sites.

Select's design team have customized these tent enclosures for specific applications; integrating high performance filters for AC power configurations up to 100 Amps and using multiple communications protocols including Gigabit Ethernet  and USB 3.0 while assuring high attenuation performance. Select Fabricators uses multiple layers of its Nova Select™ conductive fabric for the basic RF test enclosure construction. An internal or external vestibule is an important part of the design. The vestibule provides entry and exit for personnel during test procedures without compromising the integrity of the test application. The patent pending door system consists of two rows of conductive magnets with ROHS compliant Nova Select™ fabric used as a conductive gasket.

To complete the system, ventilation, high performance filters, hardened lighting and aluminum frame were designed and installed prior to testing. This RF shielded chamber system was tested and certified to Select Fabricators' and its customer's complete satisfaction. The high attenuation shielding effectiveness, independently certified, can be completed for any Select-A-Shield standard or custom tent enclosure system with full test results.
