Making Accurate Power Rail Measurements

Explore five practical tips to accurately measure ripple and noise when small AC signals ride on DC power rails. In this expert-written application note, you’ll learn:

  • Why low-voltage rails and tighter tolerance bands make accurate ripple and noise measurement a constant concern for power distribution networks.

  • How oscilloscope noise, resolution, and probing choices impact ripple and noise visibility, and what to do to improve measurement sensitivity.
  • How to measure small AC signals over large DC signals so you can identify ripple, noise, and transients riding on the voltage rail and keep the power rail clean.

  • How to apply five practical measurement tips to reduce setup noise and loading so you can make confident pass or fail decisions on power integrity.
