The Bluetooth Special Interest Group (Bluetooth SIG) adopted the first specifications for BLE 5.2 at the end of 2019. This initially concerns the new power control functions. Rohde & Schwarz has already integrated specified tests into the Bluetooth test software of its wireless testers in the R&S CMW platform. In addition, Bluetooth LE 5.2 will provide extended audio … [Read more...]
Würth Elektronik Circuit Board Technology Successfully Completes Research Project on Intelligent ARM-Hand Orthosis
In automobile production, industrial robots and production lines largely relieve people of having to work with heavy loads. This is not the case for people who work in a trade or in care, where the body can be heavily burdened by hard work. In the PowerGrasp project, a second skin provides additional strength. Following three years of research, the promising results are now … [Read more...]
Advances in MMW Isolator Design Launch Manufacturers into Stratospheric Operating Frequencies
It doesn’t take a crystal ball to know where the future of wireless is heading. With inexhaustible demand driven by 5G, 6G, and beyond, ultra-high-definition video, autonomous cars, security applications, and IoT, the sky's the limit for utilizing the higher ends of the electromagnetic (EM) spectrum. Meeting this demand requires products capable of capitalizing on the … [Read more...]
The Emerging Threat of Tactical Electromagnetic Interference & its Spread into Non-Defense Sectors
During the last five years intentional electromagnetic interference (IEMI) has emerged as a credible and increasingly likely threat to commercial and defence facilities alike, with a potentially crippling cost to individual organizations of such a localized attack. Hollywood has long used electromagnetic interference (EMI) and electromagnetic pulse (EMP) phenomena as the de … [Read more...]
The Top Five Reasons Products Fail EMI Testing
Introduction The three top product failures I see constantly in my consulting practice are (1) radiated emissions, (2) radiated susceptibility, and (3) electrostatic discharge. After reviewing and testing hundreds of products over the years, I’ve come to the conclusion that products fail these tests for five common reasons (somewhat in order of incidence); PC Board … [Read more...]
EMI Pre-Compliance Testing
Introduction This article describes how I perform pre-compliance testing for the top four EMI issues I constantly run into; conducted emissions, radiated emissions, radiated immunity, and electrostatic discharge. Of these, the last three are the most prevalent issues, with radiated emissions typically being the biggest compliance challenge during certification testing. If … [Read more...]
