Measure Power Integrity with Higher Confidence

This application note shares 10 practical techniques for measuring and analyzing DC power supplies with higher confidence. You’ll learn:

Why a baseline noise floor matters when measuring small AC signals riding on DC rails, and how to run a null measurement.
How bandwidth limits, attenuation, and probe offset choices can change measured ripple and noise results on a power rail.
How measurement loading can alter the supply under test and when a 50 Ω measurement path can become a problem.
How fast Fourier transform (FFT) analysis and triggering methods help isolate switching components and coupled noise sources on the rail.

See Power Integrity Analysis in Action

Go deeper into how to set up a real-time oscilloscope for power integrity analysis. See how a power rail probe helps you view AC offset detail across multiple rails, and how current probing plus software identifies noise sources and effects. Learn how low noise floor and high vertical resolution improve measurement confidence on real power rails.
