10 Tips for Making Your Best Power Integrity Measurements

Application Notes

Thanks to Moore’s law, electronic products contain ever-increasing functionality and features. Affordable microcontrollers enable devices and services with improved performance and richer features, such as household appliances, automobiles, medical devices, wearables, the Internet of Things, smartphones, and the cloud.

One burden designers of these products face is providing “clean” power to the devices and circuits. Designing the power distribution networks (PDN) of modern products requires significant resources of time, people, and equipment. Real-time oscilloscopes measure DC power supplies in these products.

Keysight oscilloscopes offer many software applications related to this discussion, including the Keysight D9010POWA power integrity analysis software. A software application can make accurate measurements faster and easier, reducing human error. This application note offers 10 tips and fundamental techniques for measuring and analyzing DC power supplies, as well as selecting and evaluating tools for DC power supply measurements.
