Large RF Shielded Enclosures-Giants!
Large RF Shielded Enclosures-Giants! I always say that VTT fabricates RF Shielded Enclosures to satisfy the needs of our customers, whether it's as small as our 3D Pouch, our "small test lab", or a much larger one. This year, we are receiving orders for "Testing Megastructures", very large testing enclosures. RF Shielded enclosures provide the low ambient RF environment required for Pre-Compliance EMC testing. The size of the testing enclosure is typically dependent on the size of the Device Under...

Military uses for Conductive Textiles!
Military uses for Conductive Textiles! The Department of Defense has many uses for Conductive Textiles. Obviously, the military has many sophisticated electronic devices in their vehicles, whether planes, tanks, or boats. The lives of the soldiers depend on these devices working smoothly without any interference from RFI or EMI. Proper RF Shielding allows these devices to work together efficiently in a shared electromagnetic environment. Conductive textiles are the best shielding materials for vehicles due to their light weight and flexibility....

RF Interference-Controlled by Shielding!
RF Interference-Controlled by Shielding! RF Interference (RFI) and Electromagnetic Interference (EMI) can wreak havoc with the function of electronic devices. In our wireless world, the amount of RF radiation present in our environment is always increasing. Add the man-made RF radiation to the natural forms of RFI and EMI such as snow, rain and electrical storms, solar flares, and the auroras and there's a whole lot of radiation going on around here! Three things cause an interference problem, a "noise...

Your RF Shielded Enclosure-Custom-Made!
Your RF Shielded Enclosure-Custom-Made! Almost every electronic device under production is unique! They all have one thing in common-they must pass EMC Final Compliance Testing prior to marketing them! The EMC Compliance Testing is based on different classes of accepted standards. The standards vary for each class of device. EMC Testing takes place in RF Shielded enclosures with low ambient levels of RF present. During EMC testing, devices are evaluated for the amount of RF radiation that they can perform...

EMC Final Compliance Testing-be Prepared!
EMC Final Compliance Testing-be Prepared! The Boy Scout Motto is "Be Prepared". That phrase is my cornerstone approach to everything! Applying it first in grade school and continuing from that time forward, that phrase readies me for day-to-day life and my profession. Likewise, my V Technical Textiles, Inc. experience confirms it works for every testing experience when applied wisely. Electrical devices and components must pass EMC Final Compliance Testing prior to marketing them. EMC Compliance Testing determines whether a device...

RF Shielded Enclosures-Perfect Testing Environments!
RF Shielded Enclosures-Perfect Testing Environments! You've heard me say that EMC is all about the environment. EMC means all of the electronic devices in a shared electromagnetic environment are able work together smoothly. RF Shielded Enclosures are used in testing electronic devices to assure that the devices can work in a standard environment together while not making that environment toxic for other devices. EMC Testing requires a controlled low ambient electromagnetic environment. The only electromagnetic radiation present should be that...

RF Shielded Enclosures-Designed for You!
RF Shielded Enclosures-Designed for You! Many companies come to VTT for RF Shielded Enclosures. No surprises there as we are the world leader in fabrication of portable RF Shielded Enclosures. Enclosure fabrication isn't our only strength, our design group meets with our customers to determine their specific enclosure needs. Only after discussing the various options of size, electromagnetic environment needed, and the various enclosure options available to make their enclosure match their needs do we proceed to design and build...

EMC Testing-try Pre-Compliance Testing!
EMC Testing-try Pre-Compliance Testing! As the new year approaches, new product introduction will increase. Every new electronic device must pass a Final EMC Compliance test. You shudder to think of scheduling testing, long waits for appointments, long trips to the testing center, and big testing fees! It's great when you pass the test the first time but having to retake the test is a nightmare! This year, make a change in your "usual cycle"! Try Pre-Compliance Testing in your own...
