Rohde and Schwarz NRP-Z27 - Power Sensor Module (DC to 18 GHz)

The R&S NRP-Z27/-Z37 power sensor modules turn the R&S FSMR measuring receivers into precision power meters with a wide dynamic range from -115 dBm to +30 dBm.

The R&S NRP-Z27/-Z37 power sensor modules were developed especially for level calibration using the R&S FSMR measuring receiver. These sensors act as highly accurate references for determining the absolute power level. Together with the excellent linearity of the R&S FSMR, this enables precise power calibration over the entire level range of the measuring receiver. Using an integrated power splitter, the power is fed to the integrated R&S NRP-Z27/-Z37 thermal power sensor module and simultaneously to the measuring receiver via a phase-stable cable.

Like all other power sensors in the R&S NRP family, the power sensor modules are fully self-contained power meters that are remotely controlled from the R&S FSMR, R&S NRX or any Windows PC via USB.

NRP series overview

Rohde & Schwarz offers several varieties of its NRP power sensor. The NRPxxS(N), NRPxxT(N), NRPxxTWG, NRPxxA(N) and NRP-Zxx power sensors are immediately ready for use. In contrast to conventional power sensors, no calibration is required prior to making measurements since the sensors are fully characterized over frequency, level and temperature and feature longterm stability. All calibration data is stored in the sensors, so they function as independent measuring instruments. Usually, no zeroing is required. Users can plug in a sensor and simply start measuring.
