The Rohde & Schwarz NRP18S-10 is a three-path diode power sensor engineered for precision power measurement across 10 MHz to 18 GHz. The three-path architecture with overlapping diode paths enables simultaneous measurement with smooth transitions between ranges, eliminating hysteresis, measurement delays, and differential nonlinearity. This design delivers superior signal-to-noise ratio and measurement speed while maintaining independence from modulation type and resistance to interfering signals and harmonics.
