Rohde & Schwarz NRV-Z31 30MHz-6GHz 20mW Power Sensor

The Rohde & Schwarz NRV-Z31 is a peak power sensor engineered for precise measurements of Peak Envelope Power (PEP) in modulated and pulsed signals across the 30 MHz to 6 GHz frequency band. With a maximum power rating of 20 mW and sensitivity down to 1 µW, this sensor delivers absolute calibration and plug-and-play functionality when paired with NRVS or NRVD base units.

Technical Specifications
