Ensuring clean power rails using a real-time oscilloscope
Analyzing power integrity requires making measurements such as power distribution network (PDN) impedance, power rail integrity, power sequencing, power supply rejection ratio (PSRR), and control loop response. Device designers face the challenge of providing clean power to devices such as automobiles, medical devices, and Internet of Things devices through a PDN that consists of passive components and interconnects. A well-designed PDN maintains a stable voltage from DC to the bandwidth of the switching current. It can help to optimize power consumption, minimize switching noise, reduce power supply-induced jitter, and minimize EMI problems.
Design engineers need a real-time oscilloscope and a power rail probe to measure multiple power rails at once, and to see the AC offset of the signal in better detail. A high-sensitivity current probe that can switch between a high-sensitivity and attenuated mode helps analyze battery consumption, while software helps analyze power rail noise sources and effects. Measuring at multiple temperatures helps pinpoint performance issues at temperature extremes.
