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 the...

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 for...

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 in...

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 can...

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 its...

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 interference...

Home Shielding is Smart, Protect your Family from RF Exposure!
Home Shielding is Smart, Protect your Family from RF Exposure! RF Radiation is more prevalent than ever in today's world. There are many sources of this, some natural, many human generated. We live in a world with many electronic devices. Every device adds to the E-Smog that surrounds us. Electromagnetic Hypersensitivity Syndrome (EHS), is a clinical syndrome characterized by the presence of a wide spectrum of non-specific symptoms. These symptoms include: headaches, body pain, lethargy, tinnitus, burning sensation, heart arrhythmia, and...

Pre-Compliance Testing is Important, Prepare your Product for the Final!
Pre-Compliance Testing is important, prepare your Product for the Final! I'm not talking about school here. Manufacturers of electronic devices know exactly what I'm talking about. In order for an electronic device to be marketed, it must pass Final Compliance Testing on RFI susceptibility and RFI emission standards. These standards regulate how much RFI affects the device, and how much RFI the device emits. The device must pass these rigorous Final Compliance Tests at approved testing centers in order to...
