Conductive Textiles help make Travelling Safe!
Conductive Textiles help make Travelling Safe! Planes, trains, and automobiles depend on conductive textiles in many ways. They keep the driver or pilot aware of the engagement of safety restraints by the passengers before beginning the trip. If you drive automobiles, you are well aware that there are sensors present in the steering wheel that determine if the driver is in proper position and paying attention to his surroundings. If the car wanders in its lane, sensors notice this and...

RF Shielding creates Device Compatibility!
RF Shielding creates Device Compatibility! Everyone knows some people who are very talented at what they do, but they can't work together! The mere presence of the two of them in the same room ruins the work environment. The same thing is true of electronic components, electronic devices do jobs well. When the components have to work in a shared electromagnetic environment, they have to be compatible. With people, it's their personalities that can make them incompatible, unable to work...

EMC Compliance Testing-what’s the Point?
EMC Compliance Testing-what's the Point? Every electronic device must pass EMC Compliance Testing to make it to the market! The reason for this requirement is to lessen the amount of RFI/ EMI in our environment. More importantly, it is to lessen the RFI and EMI in our environment that adversely affects the function of other devices present in the shared electromagnetic environment. All electronic devices emit RFI/EMI. In general, electromagnetic interference doesn't cause a decrease in function of the devices...

RF Shielded Enclosures-Testing at Home!
RF Shielded Enclosures-testing at Home! Preparing for Final Compliance EMC Testing is difficult. One of the best ways to prepare for this test is to prepare your product during development. Testing your product in your home environment during development builds EMC into your device from the start and is the best way to proceed. Pre-Compliance EMC Testing can be done easily at your development site. It actually saves time in development, by intercepting EMC issues along the way rather than...

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...

Small RF Shielded Enclosures-Petite!
Small RF Shielded Enclosures-Petite! RF Shielded Enclosures come in all sizes, from Megastructures to Gusseted bags! VTT is able to create RF Shielded Enclosures to satisfy their customer's needs. Electronic devices come in all sizes and must pass EMC Final Compliance Testing in order to be marketed. The Gusseted Bag is a small RF Shielded Test chamber that provides the low ambient RF environment required to perform EMC Testing. The bag, fabricated using conductive textiles, creates a Faraday Cage, blocking external...

RF Shielded Enclosures-Made for You!
RF Shielded Enclosures-Made for You! RF Shielded Enclosures are used for testing electronic devices, mainly for EMC Compliance testing. EMC testing requires a low-ambient RF environment. Portable RF Shielded Enclosures provide this unique environment using the Faraday Principle. The Faraday Principle states that the fields within a conductive material cancel out any external fields, making the electric field inside the conductive material enclosure zero. The walls of a soft sided RF Shielded consist of conductive fabric, satisfying the requirements of...

Testing Times demand logical Preparation!
Testing Times demand logical Preparation! So many things in our lives depend on test results! In my case, my Dental License depended on my Dental Board Exam results, passing is necessary to license! In the world of electronic devices, passing Final EMC Compliance Testing is necessary to market the device. Logical preparation dictates testing your device often during development in preparation for the "big day"! You know the EMC standards that your device must meet. Pre-Compliance EMC Testing in your...
