The Rohde & Schwarz NRP33TN is a thermal power sensor engineered for precise average power measurement across DC to 33 GHz. It delivers measurement capability from 300 nW to 100 mW with absolute uncertainty as low as 0.040 dB and exceptional linearity of 0.007 dB across its operating range. The sensor’s thermal architecture minimizes noise and rejects environmental thermal influences, making it ideal for calibration laboratories, metrology, and R&D environments where modulation-independent power measurement is essential.
