Howdy guys - I have an XPA-2 amp hooked up to a pair of B&W683's and am curious how many watts (in real time) I am using. I am not worried about over driving the speakers or worried that the amp is ...

Even if you don’t have a Rohde Schwarz oscilloscope, you can still enjoy their recent video about using an oscilloscope to measure power supply efficiency. Of course, you don’t have to have a scope to ...

As product performance demands continue to rise, designers building power-supply prototypes need test procedures that allow them to evaluate their designs' efficiency quickly. We will look at two ...

Every time we talk about an engine, we talk about the amount of horsepower it has. Even if we talk about electric motors in most modern EV, we tend to read the horsepower figure to determine the power ...

Always on the lookout for better ways to measure all kinds of things, researchers have published a detailed study suggesting an "elegant" improved definition for the standard unit of light power, the ...

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 ...

It all really comes down to habit. Once people get used to doing things one way — like using the word "horsepower" to refer to an engine's output — it can be exceedingly difficult to get them to ...

Take a closer look at the new EPIC I/O module (GRV-IVAPM-3) and get up to speed on how to install and configure it for your power monitoring applications. This module will allow you to measure live ...

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 ...

Always on the lookout for better ways to measure all kinds of things, researchers at the National Institute of Standards and Technology (NIST) have published a detailed study suggesting an "elegant" ...
