The Rohde & Schwarz NRP-Z11 is a universal RF power sensor delivering precise measurements across continuous wave and modulated signals from 10 MHz to 8 GHz. Its three-path diode architecture—with triple diodes per path—achieves a 90 dB dynamic range and extended measurement capability from -67 dBm to +23 dBm (200 pW to 200 mW). The sensor excels in R&D, manufacturing, and wireless communications testing, where modulation-independent accuracy and low harmonic sensitivity are critical.
