Test and measurement instruments evolve over time. The banner improvements come in performance, things like measurement bandwidth and dynamic range. These always make the trade press headlines, but ...

Half-bridge series resonant converters achieve high efficiencies and high power densities for converters over 100 W. The most common resonant topology (Figure 1) is a resonant tank comprised of a ...

In 2018, life sciences and analytical instrument makers kept up the momentum of the last few years: overall instrument sales for the 20 firms that C&EN tracks rose 6.2%. Although economic conditions ...

During my engineering studies, a lecturer in Measurement Systems made a statement that has stayed with me throughout my career: “All electronic measurements are a lie. The trick is making the lie as ...

Scientists in Finland have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures – a scale trillion times lower than ...
