4.4.1.4 Noise in Power Plots

When the target device itself consumes very little power, noise can be visible on power plots, as it becomes a relatively larger part of the measured power. This noise could be an effect of the target device interacting with a debugger in a debug session, or noise in the power supply or measurement circuits.

For example, in the current plot for low power consumption, noise is visible in the plot.

However in the current plot for higher power consumption, the noise is much less.
