Hi All, Here is a scenario: there is a noise problem in a system and you suspect the main DC power supply which operates off the 60 Hz AC mains. So, you take a scope probe, a trusty 10X Hi-Z one, connect it across the output of the supply from + to - at the output of the supply, - going to the system ground.
You see 1+ Volt peak-to-peak spikes on the scope at the fundamental switching frequency of the power supply. What is the first thing you do?
