EMC-Devices functioning in Harmony!

EMC-Devices functioning in Harmony!  All electronic devices produce electromagnetic emissions.  Electromagnetic emissions of every electronic device have to meet applicable standards.  Emissions outside of the standards interfere with function of other devices in the component.  Devices must be in compliance with EMC standards in order to be marketed.  EMC Compliance testing insures a harmonious shared electronic environment for optimal device performance. EMC-Devices functioning in Harmony!  EMC Compliance testing consists of three tests: Emissions- The Device Under Testing (DUT) is tested to...

Autonomous/Driver-Assisted Vehicles-Testing Galore!

Autonomous/Driver-Assisted Vehicles-Testing Galore!  Many of us feel that machines can't replace people.  This is especially true of the automotive driver seat!  People do not want to put their lives in the hands of a machine.  We've all dislike back seat drivers, but the thought of no driver is even scarier!  The reality of Partially Autonomous/Driver-Assisted vehicles is here.  Many cars already have AEB (Automatic Emergency Braking) systems.  My car has LKA (Lane Keeping Assist) and it's two years old!  I...

Rough Conditions Require Rugged Textiles!

Rough Conditions Require Rugged Textiles!  Conductive textiles are thin and lightweight.  Normally, these are excellent characteristics for many of their uses.  Metalized textiles are used in many electronic devices for shielding.  Electronic technology is becoming smaller all the time.  Shielding solutions must be flexible and adaptable to fit in tight spaces.  However, there are times that rugged characteristics are important.  Due to their fine structure, conductive textiles are usually not particularly durable.  The delicate nature of these shielding giants limits...

EMC Compliance Testing-“Prep” your Product!

EMC Compliance Testing-"Prep" your Product!  EMC Compliance testing is often the final obstacle to product marketing.  It's important to prepare your product for this test!  Best Practice for Final EMC Compliance Testing is Pre-Compliance EMC Testing!  Pre-Compliance Testing at your own facility beginning early in development is great preparation!  This allows identification and mitigation of problems during every step of development.  Backtracking to find problems is time consuming and frustrating!  Products developed in this way will likely pass Final Compliance...
Options in Testing Enclosures

Options in Testing Enclosures-VTT has Plenty!

Options in Testing Enclosures-VTT has Plenty!  Our EMC testing enclosures are not one offs!  Enclosures are like homes, unique features are necessary to fit the buyer's individual needs!  Size is a great place to start in Enclosure design.  The larger the product being tested, the larger the enclosure has to be.  I'm sure you've heard that big isn't always better.  VTT can provide the 3 Dimensional pouch, a compact test enclosure for small objects.  On the other hand, VTT is...

Your own Test Lab-an RF Shielded Enclosure!

Your own Test Lab-an RF Shielded Enclosure!  Best practice suggests Pre-Compliance EMC Testing early and often in product development.  The problem is the time and money wasted accomplishing offsite testing!  The lead time for testing slows things down as well.  The ability to perform testing in your own facility would be great.  Many companies have faced this problem over the years.   VTT has designed and produced portable testing enclosures for many years.  These RF Shielded Enclosures provide the low ambient...

Pre-Compliance EMC Testing-Essential in Product Development!

Pre-Compliance EMC Testing-Essential in Product Development!  Save time and money in electronic product development!  Electronic products must pass EMC Compliance testing before marketing.  It isn't essential during product development, but it makes development smoother!   EMC testing helps assure that your product meets necessary standards.  The best practice is to test early and often during development.  Waiting until the product is nearly finished almost assures failure.  Failure necessitates "backtracking" to find the problem that caused failure.  The failure point must be...
RF/EMI Shielding Curtain

RF/EMI Shielded Curtains-Privacy and Separation!

RF/EMI Shielded Curtains-Privacy and Separation!  In our lives, we use curtains for privacy, separation, and protection.  RFI/EMI Shielded Curtains are used in the same way.  RF Shielded curtains are made of conductive metalized textiles.  These curtains block the passage of RF and EMI waves.  One of the major uses of these curtains is in hospital telemetry areas.  They effectively isolate the beds in a "shielded room".  This assures that the proper information is transferred to the proper recording device.  The...

Electromagnetic Compatibility-when devices work smoothly Together!

Electromagnetic Compatibility-when devices work smoothly Together!  Devices are like people, they work best when they're compatible. Electronic devices work best when they don't interfere with each other.  Electronic devices can be interfered with in several ways.  They can be "distracted" by RF interference emitted by nearby devices.  This distraction is similar to a co-worker who is always talking.  The background "noise" keeps work quality below its potential best.  Devices that can be "distracted" are called "susceptible".  The answer to susceptibility...

RF/EMI Shielding-the Key to EMC!

RF/EMI Shielding-the Key to EMC!  Electromagnetic Compatibility Standards must be met prior to marketing devices.  The device must perform well in a shared electromagnetic environment.  It must not disrupt the performance of other nearby devices.  It must not be disrupted by its environmental coworkers.  The "potential disruption" is caused by RF/EMI outside of acceptable standards.  In the US, the FCC determines these standards.  In Canada, Industry Canada determines the standards.  Europe requires the "CE" mark that represents compliance.  Every country...
