Good RF Shielding Equals EMC!
Good RF Shielding equals EMC! All electronic devices produce RF Noise or Electromagnetic Fields. These Electromagnetic emissions can cause less than optimal device performance. There are "acceptable standards" of RF emissions allowed to be present in the component. Some devices are "susceptible" to acceptable RF radiation. Other devices may emit unacceptable amounts of RF radiation. The RF radiation of one device can adversely affect the performance of the component. That is why it is important to test devices early and...

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...

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...

RF Shielded Testing Enclosures, Rental is an Option!
RF Shielded Testing Enclosures, why buy one you can rent it? Shielded Testing Enclosures are an ideal solution for Pre-Compliance Testing. Accomplishing this testing at your site has several advantages. There is the monetary advantage, saving travel and testing fees are two areas of saving money. Saving precious time instead of waiting for appointments at busy testing centers when you can perform them in your own location on your own schedule represents another important savings area. Many industries are required to...

RF Testing in Space? How will that be Done?
RF Testing in Space? That seems like a strange question. Certainly, RF Testing in space is not being done to any great extent at this time. RF testing is done on earth for the spacecrafts and their components to make sure that their delicate electrical systems work smoothly together in space. RF testing in space seems like it could be a necessary thing to consider within the next decade. NASA's Artemis Program will return humans to the Moon in 2024. The...

Throw away your Tin Foil Hats, RF Shielded Clothing is Stylish and Comfortable Now!
In today's electronic device driven world, the human body is exposed to Electro-Magnetic Fields (EMFs) at an ever-growing rate. The sources of the EMFs are largely man-made, delivered to us via our wireless devices including: cell phones, Wi-Fi, Bluetooth devices, computers, cellular towers, high tension power lines and so many others. EMFs are not visible to you, you can't see them, touch them, feel them, taste them, or smell them. In fact, we are humans, yet the cells of our...
