Measurement practices for analyzing the real time spectra of signals and apply these methods to power rail noise to provide insight into the root cause of the problems b. While the real world is the time domain, sometimes we can gain insight about the origin of problems by looking in the frequency domain. The time domain and frequency domain properties of power rail noise is a little different than for digital signals. For some types of products, such as analog parts, mixed signal or clock generation, very low levels of power rail noise can have a big impact on performance. Sometimes the best way of finding these noise sources is by frequency domain analysis. In this seminar, we introduce the best measurement practices for analyzing the real time spectra of signals and apply these methods to power rail noise to provide insight into the root cause of the problems.
