The Rohde & Schwarz NRV-Z51 is a thermal power sensor that delivers precise average power measurements across DC to 18 GHz. It accurately characterizes both continuous wave signals and modulated or distorted waveforms through RMS weighting of spectral components, maintaining exceptional linearity across frequency, temperature, and signal variations. The sensor integrates absolute calibration memory, eliminating manual calibration factor entry and enabling immediate measurement upon connection to compatible base units.
