The Rohde & Schwarz NRVS is a highly accurate, single-channel RF power meter designed for a wide range of power measurements from DC up to 40 GHz, depending on the connected sensor. Offering compatibility with intelligent NRV-Z and URV5-Z sensors, it features automated configuration, non-volatile memory for setups, and specialized calculations for pulse peak power.
