The Rohde & Schwarz NRPC18 is a calibration kit engineered for traceable calibration of RF and microwave power sensors from DC to 18 GHz. It features N female connectors and delivers calibration uncertainty as low as 0.28% (0.012 dB) at DC to 1 MHz, extending to 0.68% (0.029 dB) at 2.4 GHz to 18.0 GHz. The kit handles test port power from 10 µW to 100 mW (–20 dBm to +20 dBm), with continuous average power to 0.5 W (+27 dBm) and peak envelope power to 40 W (+46 dBm) for pulses up to 1 µs.
