for Power Reflection Meter R&S®
Key Facts
  • Frequency range from 25 MHz to 4 GHz (sensor-dependent)
  • Measurement of average power, average burst power, peak power, crest factor, CCDF and mismatch
  • Low insertion loss
  • Very good matching
  • Excellent intermodulation characteristics
  • Direct power monitoring on PC

Brief Description The R&S®NRT-Zxx directional power sensors are self-contained measuring instruments. They can be connected directly to the R&S®NRT2 or, via the R&S®NRT-Z5 USB interface adapter, to the PC (communications via USB).
Features & Benefits Direct power monitoring on PC The R&S®NRT-Zxx directional power sensors are fully calibrated, independent measuring instruments that can also be used without the base unit. The R&S®NRT-Z5 USB interface adapter enables direct connection to a laptop/PC. The R&S®NRT-Z14, R&S®NRT-Z43 and R&S®NRT-Z44 power sensors make high-precision power and reflection measurements extremely cost-effective. Direct monitoring on a PC is very useful in applications where data needs to be collected (e.g. in development labs and for maintenance of base stations) as well as for purely remote controlled applications such as power monitoring in transmitter stations and EMC test systems. The R&S®V-NRT Windows user interface (supplied with the sensors) allows users to define measurement functions and also display and store individual results and series of measurements. Average power (RMS value) This function returns the average value of the power for any type of test signal (modulated, unmodulated or several carriers). It features a measurement range of 35 dB to 40 dB and high measurement accuracy. Peak envelope power (PEP) and crest factor Both parameters provide information on the peak power of a modulated envelope and describe the overdrive characteristics of transmitter output stages. The result of the crest factor measurement is referenced to the average power and displayed in dB. Measurements are performed using a video bandwidth that is adjustable in several steps, so that even short-time and high-power peaks can be determined. Average burst power This function can be used to measure modulated and unmodulated bursts based on the average power and the duty cycle. Both can be defined by the user or determined automatically by the power sensor. Complementary cumulative distribution function (CCDF) This function measures the probability of the peak envelope power exceeding a preset threshold so that the amplitude distribution of signals with an unknown envelope can be determined.''
