on’t confuse the 1-port PDN probe with a 10 to 1 ratio, passive oscilloscope probe. They have little in common with a 1-port PDN probe
other than the improvement of the signal-to-noise

ratio achieved by the lack of probe attenuation. The 1-port PDN probe is special in many respects and more complicated than meets the eye. This article serves as an introduction to the 1-port PDN probe but also provides examples of how it can be applied to get high-quality measurements quickly and easily.
