Rohde & Schwarz NRV-Z2 18 GHz 50 Ohm 500 mW Power Sensor

The Rohde & Schwarz NRV-Z2 is a diode power sensor delivering accurate measurements across 10 MHz to 18 GHz in 50 Ohm systems. It measures power from 20 nW to 500 mW with absolute calibration, requiring no prior reference calibration. The sensor handles maximum average power of 2 W and peak power to 10 W, making it suitable for RF and microwave characterization in research, development, and production environments.
