The Rohde & Schwarz NRP50T is a thermal power sensor delivering accurate power measurements from DC to 50 GHz. Built for R&D, production, and calibration environments, it combines thermal stability with high precision across a dynamic range of -35 dBm to +20 dBm (300 nW to 100 mW). The sensor’s thermal design maintains measurement accuracy under varying environmental conditions, making it suitable for both continuous-wave and modulated signal analysis.
