The Rohde & Schwarz NRP8SN is a three-path diode power sensor engineered for accurate RF power measurements from 10 MHz to 8 GHz. Its three-path technology reduces measurement noise significantly, achieving a lower measurement limit of -70 dBm and a dynamic range of 93 dB. The sensor operates across a power range of -70 dBm to +23 dBm (100 pW to 200 mW), delivering measurement speeds exceeding 50,000 readings/s in continuous mode and supporting 10,000 triggered measurements/s. It handles both CW and modulated signals of any bandwidth with precise average power determination independent of modulation type.
