The Rohde & Schwarz NRP series comprises intelligent power meters engineered for precision measurements across RF and microwave applications. Each sensor integrates an embedded CPU, enabling standalone operation or seamless integration with base units and PCs via digital interface. Calibration data resides within the sensor itself, eliminating external dependencies and ensuring measurement integrity across R&D, manufacturing, and field service environments.

Representative Sensor Models:
Two-path diode sensors (NRP-Z11/Z21) deliver 80 dB dynamic range and 1,500 measurements/s across 10 MHz to 8 GHz or 18 GHz.
Three-path diode sensors (NRPxxS/SN/SN-V) achieve 93 dB dynamic range with lower measurement limits to –70 dBm and frequency coverage extending to 67 GHz.
Average power sensors (NRP18A) cover 8 kHz to 18 GHz with impedance matching (SWR) less than 1.25 (8 kHz to 2.4 GHz to 8.0 GHz).
Wideband sensors (NRP-Z8x) provide >9,000 measurements/s in buffered mode, with frequency coverage to 44 GHz.
– Key Features
• Dynamic range from 80 dB to 93 dB depending on sensor type
• High measurement speed up to 50,000 readings/s in fast continuous average mode
• Measurement range spanning –70 dBm to +23 dBm across sensor variants
• Frequency coverage from 8 kHz to 67 GHz
• Versatile triggering for time-domain signal analysis
– Typical Applications
