Directional Power Sensors

Product Overview The Rohde & Schwarz NRT-Z44 directional power sensors are fully calibrated, independent measuring instruments that can also be used without a base unit. These directional power sensors simultaneously measure forward and reverse power and calculate additional parameters such as load matching. The Rohde & Schwarz NRT-Z44 directional power sensors feature good matching, low insertion loss and excellent intermodulation characteristics. Conventional directional power meters only measure RF and microwave signals that have an unmodulated envelope. The Rohde & Schwarz NRT-Z44 directional power sensors have been designed to also meet the requirements of digitally modulated signals. The key factor is their ability to correctly measure the average power (RMS value) of a signal irrespective of its envelope. The sensors behave like a thermal power meter and offer the best accuracy and measurement range (35 dB to 40 dB).
