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 ...

Recently, a reader wrote to me seeking a copy of a paper on measuring the transient peak-to-average power ratio of DTV signals. So perhaps the topic of DTV signal power, which is so different from ...

Steve Sandler has written several power supply design articles for Power Electronics Technology magazine and also powerelectronics.com. Now, he decided to write a book that covers all the major ...

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 ...

Washington again teeters in a state of strategic freefall—similar to the periods of ambiguity immediately after World War II and the end of the Cold War. During such eras of indecision, when national ...

Which is the best current sensor for your power measuring application? Solid-core current sensing technology provides good performance at low cost. But split-core sensors are making strong progress ...

Measuring power supply ripple properly is an art in itself. Figure 1 shows an example where a neophyte engineer grabbed a scope and got it all wrong. His first mistake was using a scope probe with ...

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 have published a detailed study suggesting an "elegant" improved definition for the standard unit of light power, the ...

The power consumption measuring instrument 'IoTaWatt ' that can measure the power consumption of up to 14 lines at the same time and wirelessly connect from a smartphone or PC to check the measurement ...
