The Rohde & Schwarz NRP-Z55 is a thermal power sensor that delivers precise power measurements across DC to 40 GHz using a thermoelectric test cell. It covers a continuous 300 nW to 100 mW range without requiring range switching, with exceptional linearity of 0.007 dB (0.16%) up to 67 GHz. The DC-coupled design enables measurements from 0 Hz, supporting reference to low-frequency and DC standards.
