In previous videos, Sandler discussed measurement of power supply signals such a switch-node waveforms and output ripple. In this video, he delves further into time-domain measurements of power supply signals using oscilloscopes, sometimes in combination with specialized adapters such as current injectors.
He presents examples of various waveform anomalies and discusses techniques and tips for observing them as well as pitfalls to avoid. Sandler also advises designers on minimum and recommended specifications for oscilloscopes in order to be able to catch the types of waveform anomalies discussed here.
