The Rohde & Schwarz NRP33S is a three-path diode power sensor for precision RF and microwave power measurements from DC to 33 GHz. It delivers measurement accuracy of ±0.35 dB across a 93 dB dynamic range, with power measurement capability from -70 dBm to +23 dBm (100 pW to 200 mW). The sensor supports continuous measurement speeds up to 100,000 readings/s and triggered operation at up to 100,000 measurements/s, making it suitable for R&D, manufacturing, and field service applications across CW and modulated signal types including GSM, 3GPP, LTE, LTE-Advanced, and 5G.
