Power Integrity Measurements With R&S®RTP Oscilloscopes
Performing power integrity measurements on power rails with small voltages and increasingly tighter tolerances is a challenge using standard oscilloscopes. Using standard 500 MHz passive probes with 10:1 attenuation can contribute to measurement noise, overstating the peak-to-peak voltage and masking signal content. The problem with standard probes is that they do not have sufficient bandwidth to isolate coupled signals.
This whitepaper by Rohde & Schwarz shows how R&S®RTP oscilloscopes can perform more accurate power rail measurements by isolating coupled signals. R&S®RTP oscilloscopes utilize R&S®RT-ZPR20 and R&S®RT-ZPR40 power rail probes with a 1:1 attenuation ratio, very low noise, and sufficient bandwidth to preserve critical signal content.
