In summary, the power analysis software option for Teledyne LeCroy’s HDO4000 oscilloscopes automates measurement and analysis of the operating characteristics of power-conversion devices and circuits. It automatically detects and measures turn-on and turn-off times as well as conduction losses. Areas of power loss are marked by a color-coded waveform overlay. A streamlined UI guides users through various stages of analysis. There are operating modes for power-switching device measurements, control-loop modulation analysis, and line-power harmonics.
