The Rohde & Schwarz NRP18A is an average power sensor engineered for precise RF and microwave power measurements from 8 kHz to 18 GHz. Built on three-path diode technology, it delivers a 93 dB dynamic range across CW and modulated signals with measurement speeds up to 10,000 readings per second. The sensor interfaces via USB TMC connectivity and pairs with the R&S NRX power meter, NRP2 base unit, and compatible Rohde & Schwarz instruments. Its compact form factor—110 mm × 27 mm × 35 mm, weighing 0.2 kg—suits laboratory and field deployments.
