Today, advertisements for Camp Lejeune lawsuit settlements are frequently seen on cable and network TV. Another frequently cited water disaster occurred in Flint, Michigan. Detecting Lead in Drinking Water On April 25, 2014, the City of Flint changed their water supply source from Lake Huron water (supplied by Detroit) to the Flint River. Subsequently, water […]
FAQ
Experiments bring hope for 6G above 100 GHz
Efforts to explore and “unlock” this frequency region require an interdisciplinary approach with high-frequency RF semiconductor technology. The THz region also shows great promise for many application areas ranging from imaging to spectroscopy to sensing.
How test executives automate equipment and processes
Working through test-program sets and drivers, test executives let engineers organize tests into logical sequences. They provide user interfaces for test technicians and store test results for analysis. Manufacturers of electronic and electromechanical devices rely on test instruments to generate stimuli and measure responses. While manually performing tests on the engineering bench might work for […]
How can sensors protect vulnerable areas? Part 2
Part 1 of this three-part blog addressed air quality monitoring in cities and populated areas. Less densely populated areas such as a rain forest may require different approaches. In addition, water quality monitoring in outdoor locations as well as clean drinking water from processing stations provide additional sensing opportunities. Part 2 will address these areas. […]
How to specify and use voltage references
Voltage references are small components that can have a significant impact, either positive or negative, on system performance. They are precision devices that maintain a constant voltage output even in the presence of changes in temperature, input voltage, and other external parameters. When measuring the analog world voltage, references ensure that data converters, detection circuits, […]
How modularity benefits test systems
By understanding the key issues at every phase of the product lifecycle, engineers can make decisions that result in flexible, reliable, and scalable test systems. Taking a modular approach to test system development can accelerate development and mitigate risk throughout the entire product lifecycle. When it comes to designing and building automated test systems, today’s […]
What’s the difference between transceivers and transponders?
Transceivers and transponders are types of communication devices. They can operate with RF or optical technologies. They are used in various environments, from terrestrial to undersea and outer space. Basic transceivers and transponders provide two-way links in various types of networks. Specialized devices like muxponders increase available bandwidth, extend network reach and improve network efficiency. […]
What is unshielded twisted pair cable and where is it used?
Contributed by Frances Richards Unshielded twisted pair (UTP) cable is a widely used data communication cable consisting of anywhere from two to 1800 unshielded twisted pairs of 100-ohm copper encased in an outer plastic jacket. This type of cable has no metallic shield, which keeps the diameter streamlined but offers minimal protection against electrical interference. […]
Test methods for mmWave AiP designs bring tradeoffs
Engineers have several mmWave over-the-air test methods available for evaluating phased-array antennas used in antenna-in-package designs. Each has pros and cons.
PCB design best practices for ECAD/MCAD collaboration
By Alex Grange, Siemens EDA As designs grow in scope and complexity, collaboration between the electronic and mechanical domains is even more important. For example, as PCB designs face tighter requirements, problems resulting from electromechanical interference are becoming more common. Handling these problems across disciplines requires constant collaboration and synchronized data. What isn’t working today […]
