The Rohde & Schwarz NRVS is a precision power meter for measuring power, level, and voltage across DC to 40 GHz. It accommodates a dynamic range from 100 pW to the kW range through interchangeable intelligent sensors with embedded calibration data and temperature compensation. The instrument eliminates manual calibration procedures and delivers error-free measurements in R&D, quality control, and production environments.
