The Rohde & Schwarz NRP18TN is a thermal power sensor for precise RF and microwave power measurements from DC to 18 GHz. Designed for research, development, production, and calibration environments, it delivers high accuracy across a dynamic range of −35 dBm to +20 dBm (300 nW to 100 mW) with exceptional linearity of 0.007 dB (0.16%). The sensor features an N-type male connector, dual USB and LAN interfaces with PoE support, and a built-in trigger I/O port. Internal calibration verification confirms sensor functionality and measurement integrity. Impedance matching across the frequency band—SWR < 1.03 from DC to 100 MHz and < 1.06 above 100 MHz to 2.4 GHz—minimizes reflection losses and measurement uncertainty.
