The Rohde & Schwarz NRV-Z2 is a diode power sensor engineered for accurate RF power measurement in 50 Ω systems. Operating across 10 MHz to 18 GHz, it delivers true RMS power readings with measurement capability from 20 nW to 500 mW. An integrated attenuator pad enables medium-sensitivity applications, reducing mismatch and accelerating level measurements—bridging the performance gap between thermal and high-sensitivity detectors for power levels between 10 µW and 100 µW.
