In this article, power rail voltage measurement uncertainty is examined using several different probe configurations to monitor VCore measurements on a Picotest S2000 load stepper board. The results reveal measurement variations up to 27 mV — a level of uncertainty that can completely mask the performance improvements engineers are seeking from advanced VRM technologies. Read on to learn how engineers can trust their measurements when the uncertainty exceeds the performance gains they are trying to validate.
PicoScope 7 boasts a range of enhanced features and functionality, making it the ideal choice for engineers and technicians looking for precise, reliable tools for their test and measurement needs.
Recently, Signal Integrity Journal caught up with Todd Cutler, Keysight’s VP and General Manager for Design & Test Software about product development, innovation, and the latest developments in SI/PI design.
Understanding how to make and interpret power supply impedance is very useful for optimized, low noise power supply design. With a simple pair of homemade probes, it’s easy to make the measurements using a compact VNA. Read on to find out how.
