Directional Power Sensors :NRT-Z14/NRT-Z43/NRT-Z44
These power sensors can be used as self-contained measuring instruments with digital interface even without the base unit. In addition to a directional coupler and analog section, they comprise a processor kernel for control of the hardware and remote interface and for processing the measured data (temperature compensation, linearization, zeroing and frequency-response correction). This compact concept
provides a wealth of measurement functions without the restrictions of conventional analog solutions.
Many applications call for continuous monitoring of power and reflection, e.g. to enable fast reaction in case of any damage to the antenna. Apart from providing
high accuracy, the measuring instrument must not affect SWR and attenuation
in the antenna feeder nor should it generate any interfering signals. This means very good matching, low insertion loss and excellent intermodulation characteristics: all these features are of course provided by the Directional Power Sensors: NRT-Z14,
NRT-Z43, and NRT-Z44 as standard. On top of this, the sum power is indicated when a multicarrier signal is applied a feature rarely found in other directional power sensors. Since the length of the connecting cable is not critical because of digital datatransfer, the Directional Power Sensors: NRT-Z14, NRT-Z43 and NRT-Z44 can be fitted where they measure most accurately: at the antenna feedpoint.
