eGuide Overview

This eGuide offers practical tips for fast, accurate power integrity measurements, essential for modern electronics with lower power rail voltages and tighter tolerances. It covers five key techniques: optimizing viewing, reducing noise, ensuring sufficient offset, assessing switching and EMI, and accelerating measurements. The guide highlights the use of low-noise oscilloscopes, 1:1 probes with built-in offset, and proper settings such as vertical scaling and bandwidth limits. It also recommends frequency-domain analysis and fast update rates for more reliable results. Paired with the R&S®RT-ZPR20 power rail probe, R&S®RTO and R&S®RTE oscilloscopes deliver superior power integrity testing.
