Power monitoring is undertaken for a variety of reasons: to determine the cause of a power-related problem, to confirm that the supply can support added loads, to gather data that might aid in ...

Accurately measuring the power in a laser beam is a difficult proposition. There are nearly as many different kinds of meters as there are lasers, and none of them are cheap. If you tried to use a ...

A common question I get asked relates to how I go about measuring power consumption for devices. Some people are coming at this from a perspective of pure curiosity, others are looking so save money, ...

A group of researchers at NIST working with engineers from Colorado-based Scientech has developed a new approach to measuring laser power using a mirror and a scale. This method, which measures the ...

Measuring RF Power Sensor Nonlinearity RF power sensor linearity is a commonly misunderstood topic. To obtain the most accurate power measurements, though, you need to understand what linearity is, ...

Who has more power in the labor market, workers or employers? One economist has come up with a new economic indicator to try to measure it. It's one thing to quit your job and a completely different ...
