The Rohde & Schwarz NRV-Z1 is a high-sensitivity diode power sensor engineered for precise average power measurements across 10 MHz to 18 GHz. Built on zero-bias Schottky diode technology, it delivers exceptional dynamic range from 100 pW (−70 dBm) to 20 mW (+13 dBm) with linearity uncertainty of 0.03 dB. Performance extends into the micro-watt region where response approximates thermal sensor behavior, making it ideal for modulated signal characterization and harmonic RMS weighting.

– Key Features
Maintains frequency and temperature-independent linearity beyond the square-law region up to 20 mW. Zero-bias Schottky diode architecture eliminates bias network losses while enabling sub-picojoule sensitivity. Low display noise of 40 pW ensures reliable measurement of weak signals without sacrificing dynamic range headroom.
– Typical Applications
Suitable for characterizing low-level RF/microwave signals, validating modulated signal profiles, measuring harmonic content with RMS weighting, and supporting precision power audits across UHF and microwave bands.
– Compatibility & Integration
Works directly with Rohde & Schwarz NRVD, NRVS, URV35, and URV55 power meter base units via N-type male connector interface.
