Modern electronic devices demand increasingly precise and clean power supplies. As supply voltages decrease and tolerances tighten, accurately measuring ripple and noise becomes crucial.
Engineers debugging face the challenge of detecting and quantifying these small AC signals riding on top of large DC voltages. Traditional measurement techniques often fall short due to limitations in oscilloscope performance and probe characteristics.
This application note addresses these challenges by providing practical guidance on optimizing measurement setups. By understanding the impact of factors such as oscilloscope noise, probe attenuation, input impedance, and probe loading, engineers can significantly improve the accuracy and reliability of their power supply measurements.
