Rohde and Schwarz NRP-Z28 – Level Control Sensor (10 MHz – 18 GHz)

Rohde and Schwarz NRP-Z28 – Level Control Sensor (10 MHz – 18 GHz)

The R&S NRP-Z28/-Z98 level control sensors were developed especially to feed power to the DUT and monitor the power at the same time. The sensor’s integrated power splitter splits the signal into two equal power parts. One part is measured by the integrated power sensor and displayed on a Rohde & Schwarz signal generator, on the R&S NRX base unit or on a laptop/PC. The other part, which is identical to the measured part, is output at the sensor’s RF output and can be directly fed to the DUT.

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.
