Rohde and Schwarz NRV-Z55

The Rohde & Schwarz NRV-Z55 is a thermal power sensor engineered for precise RF power measurements across DC to 40 GHz. It delivers accurate readings from 1 µW to 100 mW and 100 pW to 30 W, with a maximum average power handling of 300 mW and peak power capability of 10 W (1 µs pulse). The sensor maintains excellent impedance matching and frequency-independent linearity, making it suitable for RF engineering, system integration, and laboratory environments.
