Verifying Power Integrity For DDR Memories

One of the key challenges for maintaining signal integrity with DDR memories is to keep signal integrity in the presence of power and ground rail fluctuations. The ripple and noise on the power distribution network can negatively impact clock and data jitter, which has a direct impact on data transfer performance. The R&S®RT-ZPR20 power rail probe is a specialized oscilloscope probe for very low-noise measurements on power rails that is with integrated offset, allowing for zoom in on the ripple sitting on top of the power rail voltage.
