RF Emissions and RF Susceptibility, EMC Test Devices Early and Often in Development!

RF Emissions and RF Susceptibility, EMC test devices early and often in development! RF Emissions- every electronic device emits RF waves during function.  Some of these RF waves are acceptable in the environment.  Some of them can adversely affect the function of other nearby devices.  The RF Emissions should be checked early and often during development.  This process prevents the need to change the device design completely late in the game. RF Susceptibility- If RF waves in the area...
Maker Education

What is Maker Education, What does it Accomplish?

What is Maker Education, What does it accomplish?  Maker Education is a project-based learning experience.  It incorporates hands-on experiences along with didactic learning, facilitating education.  The projects focus on problem solving by having students take a project from concept to reality.  Maker Education involves integrating several educational areas:  Science, Technology, Engineering, Art, and Math (STEAM).  The project could teach the roles of science of electricity, the technology and engineering of a circuit, the art of a light display, and...
Anti-Radiation Clothing

Top Five Reasons for Wearing Anti-Radiation Clothing!

You may have heard of Anti-Radiation Clothing... and the exposures that it deals with are certainly getting more prevalent.. This guide will help you understand what it is and why it is becoming increasingly necessary: 1. Protection from the "Natural Environment" Believe it or not, today's "Natural Environment" is more full of naturally generated Electromagnetic Radiation (EMR) than ever! EMR is produced naturally by the sun, our atmosphere (the auroras), and the earth itself as low level electromagnetic fields.  Unless we...
EMC Test Enclosure

EMC Test Enclosures make Pre-Compliance Testing Easy!

EMC Test Enclosures make Pre-Compliance testing easy!  Manufacturers of electronic components know the importance of pre-compliance testing.  Their components must function smoothly together with many other components simultaneously.  The emission testing checks for RF emissions from the component.  There are strict standards for the level of RF emissions that components are allowed to produce.  Combine this with susceptibility testing, which is done to confirm that the component will be able function flawlessly in the presence of ambient RF levels...
EMC Tests

Reverberation Chambers Two Styles, One Great EMC Testing Method!

Reverberation Chambers, Two Styles, one Great EMC Testing Method!  EMC Testing is typically done in metal lined testing chambers.  The metal blocks any exterior RF noise from entering the testing chamber, interfering with the EMC testing that you are performing.  It's just the Device Under Testing (DUT) and the applied frequencies that are used in the test.  The problem is, the metal that keeps the "ambient noise out" allows reflection of the testing frequencies off the inside walls of...
Electromagnetic Hypersensitivity

Electromagnetic Hypersensitivity-help is hard to find, but it’s Available!

Electromagnetic Hypersensitivity-help is hard to find, but it's available!  For years, some individuals have reported a wide range of non-specific health problems that they attribute to low-level exposure to electromagnetic fields, (EMF).  The symptoms include:  headaches, body pain, lethargy, tinnitus (ringing in the ears), nausea, burning sensation, heart arrhythmia, and anxiety.  The World Health Organization (WHO) said that "no adverse health effects have been established as being caused by mobile phone use".  The WHO, along with the International Agency...
Reverberation Chamber

The Reverberation Chamber is a very useful Tool in Automotive Testing!

The Reverberation Chamber is a very useful Tool in Automotive Testing! The Reverberation Chamber is a very useful tool in Automotive Testing.  This is especially true in the ElectroMagnetic Compatibility (EMC) area.  Automotive Industry is constantly increasing its EMC standards.  The tests in the Automotive Industry are the ISO 114 52-2, CISPR-25, and the EN 61000-4-21 tests.  United States based vehicle manufacturers market their vehicles worldwide, so these standards are always incorporated in their basic company standards. These standards are increasing...
EMI EMC Testing

Reverberation Chamber EMC Testing, A new Standard in several Sectors! Learn About it at EMC Live!

Reverberation Chamber EMC Testing, A new Standard in several Sectors!  Due to the rapid proliferation of electronic devices, concerns about electromagnetic interference have increased.   There is concern about the impact of electromagnetic interference on human health.  There is also concern about the effect of ElectroMagnetic Interference (EMI) on the "health" of crucial electronic equipment.  Critical electronic equipment that is required to function properly at all times.  EMI can cause components to become "distracted", and malfunction.  This type of interference...

Steve Frierson Presents at EMC LIVE Automotive on 06/08/2021-Register for Free!

V Technical Textiles, Inc.'s Technical Consultant, Steve Frierson, presents at EMC LIVE Automotive on 06/08/2021 at 12 PM Eastern time.  His topic is "Automotive Testing Utilizing a Portable Vibrating Intrinsic Reverberation Chamber". Reverberation testing for EMC Compatibility has become a major test method in the Automotive, Aerospace, and Defense Sectors. The EMC tests that the Reverberation Chamber is used for are: Susceptibility Testing- This test determines whether the Device Under Testing (DUT) is susceptible to EMI that will be present in...
Eliminate Crosstalk

Cable Sleeves Eliminate “RFI Crosstalk”, keeping Data Secure!

Cable Sleeves Eliminate "crosstalk", keeping Data Secure.  Cables are the way that information is transferred between computers.  Crosstalk refers to electromagnetic interference from one unshielded twisted wire pair  to another unshielded twisted wire pair travelling parallel with each other.  Electric signals passing through wires create magnetic fields that interact with each other.  A wire can be either a "transmitter" or a "receiver" of electromagnetic noise.  Both forms of interference/noise affect the data quality negatively.  There are two ways of stopping...
