Oscilloscopes measure current and voltage and, through the magic of mathematics, calculate power. Unfortunately, power comes in a large number of guises: instantaneous, real, apparent, and reactive.

As FPGA devices include more logic, memory and special functions, such as memory interfaces, DSP blocks and multiple high-speed SERDES channels, and move to successively leading edge process ...

When you measure RF emissions with a spectrum analyzer, you may need to measure the total power contained in a spread-spectrum signal. FCC part 15, subpart E (Ref. 1) requires these power measurements ...

The growing demand for efficient battery testers. How to calculate ac power requirements. Calculating ac power per phase for a three-phase system. One major factor driving the lithium-ion battery ...
