The Rohde & Schwarz NRP-Z61 is a three-path diode power sensor delivering precise average power measurements across 50 MHz to 50 GHz. Built on patented three-path technology, it employs three separate diode paths operated in their optimal detector ranges to achieve high accuracy independent of modulation type. This architecture minimizes interference and harmonic effects, performing similarly to thermal power sensors. The sensor operates standalone via USB connection to a PC or integrates with the R&S NRP2 base unit.
