    Accurate ripple and noise measurements on power rails require a high-bandwidth oscilloscope and a dedicated probe to perform low-noise measurements and provide the offset capability to zoom in on top of the DC voltage. The R&S®RT-ZPR20 power rail probe as well as the R&S®RTE and the R&S®RTO digital oscilloscopes are excellent tools for this measurements.
