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-Ideal EMC Testing Environments!
RF Shielded Enclosures-Ideal EMC Testing Environments! We all know that all electronic devices have to pass Final EMC Compliance testing before they are marketed. RF Shielded Enclosures provide ideal conditions for performing Pre-Compliance EMC testing. Compliance testing determines whether or not the device is emitting RF and Electromagnetic radiation that will affect the performance of devices in their shared workspace, or if the device is sensitive to other electromagnetic phenomena. RF Shielded Enclosures create a low ambient RF environment as...

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...

Testing Situations-Prepare for them!
Testing Situations-Prepare for them! You remember it from school, from the first day of class, you knew that there would be a "Final Test". The "Final" would determine whether you would move on to the next level, or whether you would have to repeat the test! Preparation for the final was very important. A parallel situation to the "Final Test" exists when developing a new electronic product for marketing. Commencing with development is the first step for the device toward...

EMC-Devices Functioning Optimally Together!
EMC-Devices Functioning Optimally Together! Electromagnetic Compatibility means devices can function at their best in a shared environment. All electronic devices create electromagnetic fields while they are working. Some components of these RF emissions can potentially interfere with the optimal function of devices. In the United States, the FCC has regulatory authority over many kinds of consumer electronics. FCC Standards control what emissions devices can make, and a standard for how much RFI a device must tolerate while operating. Additionally, there...
