The Rohde & Schwarz NRV-Z51 is a thermal power sensor that delivers high-accuracy RF and microwave power measurements across a wide dynamic range using a thermal test cell. Operating from DC to 18 GHz, it measures continuous power from 1 µW to 100 mW and is compatible with multiple Rohde & Schwarz power meter base units including the NRVS, NRVD, URV35, and URV55 platforms.
