Page 9: Product Description
Key characteristics and key features The R&S RT-ZPR20/40 power-rail probe is designed for power integrity measure- ments. The R&S RT-ZPR20/40 is specifically built to measure small signals in the millivolt range with very large DC-offset components up to ±60 V. It is thus per- fectly suited to measure small perturbations on DC power rails. -
