Power Integrity Tests of power supply rails are best performed with an oscilloscope. Features such as histogram and the free-run mode are helpful in this process.

Given the increasingly lower direct voltages and tolerances on the power rails, oscilloscopes continue to be an important tool for development teams dealing with power integrity measurements. The ongoing trend towards lower voltages and tolerances has made power rail probes important companions to oscilloscopes.
