Power Sensors R&S^®NAP-Z 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). The R&S^®NAP-Z power sensors are available for performing measurements in the frequency range starting from 200 kHz or on powerful sources with a nominal power of up to 1 kW or 2 kW. The compact concept allows and ensures measurement functions without the restrictions of conventional analog solutions.

Directional Power Sensors R&S®NRT-Z

Power Sensors NRT-Z can be used as self-contained measuring instruments with digital interface even without the basic 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 allows a ensures of measurement functions without the restrictions of conventional analog solutions.

Average power (rms value)

This measurement function returns for any type of test signal - whether modulated, unmodulated or several carriers - the average value of he power, ie a result as provided by a thermal power meter. It features a measurement range of 35 dB to 40 dB as well as high measurement accuracy.

Peak envelope power (PEP)and crest factor

These two parameters provide information on the peak power of a modulated envelope and thus describe the overdrive characteristics of transmitter output stages.The result of the crest factor measurement is referred to the average power and read out in dB.The measurements are carried out with a video band width adjustable in several steps and allow determination even of short-time, high power peaks generated, for example, by CDMA base stations.
