New Security Risk Affects Sensors in Cardiac Devices, Consumer Electronics

 

Analog sensors within cardiac devices and consumer devices are vulnerable to deliberate EMI signal injection attacks, according to research results recently published by an international team of scientists. Researchers from the University of Michigan, University of Minnesota, University of Massachusetts, Harvard Medical School, Korea Advanced Institute of Science and … [Read more...]

Growling in Hi-fi and Stereo

 

In the last couple of posts I’ve been discussing ground loops and bonding and I made a comment that at the higher frequencies, i.e. VHF/UHF and higher multiple point grounding is used. It occurs at these higher frequencies because of capacitive coupling whether we planned it that way or not. The so-called ground loop exists whenever there are multiple ground connections … [Read more...]

Aeroflex, Ltd., a provider of high performance microelectronic components and test and measurement equipment, has released a new generation of wide-bandwidth RF signal generators and analyzers in PXI format for RF component and wireless device testing to latest standards, including WLAN 802.11ac. The combination of the PXI 3050A low noise RF signal generator and the PXI 3320 … [Read more...]

Field Probe Calibration Service Expanded to Cover All Frequencies in IEC 61000-4-3

 

EMC emission and immunity testing provider Teseq has expanded its field probe calibration services to cover all frequencies defined in IEC 61000-4-3. The expansion enables the company to offer field probe calibration data to 6 GHz and is reportedly the first step in a two-year program to install 18GHz probe calibration capability. “Our fully-accredited test facility now … [Read more...]

EMI Simulation Software Expands Library with 23 New Radio System Models

 

CAE software developer Delcross Technologies has announced the release of Electromagnetic Interference Toolkit (EMIT) Version 3.3. Ideal for companies working in the aerospace, telecommunications, defense and automotive industries, EMIT is a software tool for the prediction of cosite interference/EMI within complex RF systems containing multiple receivers, transmitters, … [Read more...]

Electromagnetic Fields May Find Use as Treatment for Parkinson's Disease

 

Scientists at Lawson Health Research Institute in London are hopeful electromagnetic fields (EMFs) can be used to treat debilitating symptoms in neurological disorders, following the completion of a study that demonstrated their altering effect on brain activity and physical responses. The research comes at a time when much of the global interest regarding EMFs is focused on … [Read more...]

Could You Show the Path of the 310uA Current through the Victim (E-Field Coupling)?

 

Editor’s note: This question was asked in response to Interference Technology’s recent webinar by Keith Armstrong. To view the webinar, click here. Question: Could You Show the Path of the 310uA Current through the Victim (E-Field Coupling)? Answer: Good question, because being able to accurately visualise where the stray current flows is an important part of the skills we … [Read more...]
