The Rohde & Schwarz NRV-Z3 is a zero-bias Schottky diode power sensor engineered for precise RF and microwave power measurements in 75 Ohm systems. Operating from 1 MHz to 2.5 GHz, this high-sensitivity detector measures average power from 100 pW to 13 mW with exceptional linearity and minimal noise. The NRV-Z3 integrates directly with Rohde & Schwarz power meter base units, making it ideal for applications demanding sub-microwatt resolution across modulated and unmodulated signals.
