Are ripple and noise riding on top of your power supply? Shrinking voltage tolerances in next-gen integrated circuits mean even the slightest power supply ripple can destabilize circuits. Catching smaller, faster AC signals and reducing them is crucial to ensuring your power rail is clean.
Your test setup is key. The latest Keysight application note explains how oscilloscope front end noise, probe attenuation ratio, and impedance affect your ripple and noise measurements.
See the ideal configuration demonstrated with the new InfiniiVision HD3 Series oscilloscope and discover how a 14-bit ADC and ultra-low noise floor reveals the signal errors you’ve been missing.
