Teledyne LeCroy Power Analysis Option HDO4K-PWR facilitates fast measurement and analysis of the operating characteristics of power conversion devices and circuits. Critical power switching device measurements, control loop modulation analysis and line power harmonic testing are all simplified with a dedicated user interface and automatic measurements. Areas of turn-on, turn-off and conduction loss are identified with colour-coded waveform overlays for faster analysis. Power Analyzer provides quick and easy setup of voltage and current inputs and makes measurements as simple as the push of a button. Tools are provided to help reduce sources of measurement errors and the measurement parameters provide details of single cycle or average device power losses. Beyond the advanced power loss measurement capabilities, the Power Analyzer modulation analysis capabilities provide insight to understand control loop response to critical events such as power supply soft start performance or step response to line and load changes. The Line Power Analysis tool allows simple and quick pre-compliance testing to EN 61000-3-2.
