Description

Accurate average power measurements for EMC applications
Key Facts
  • Measurement range: -67 dBm - +23 dBm
  • Frequency range: 9 kHz to 6 GHz
  • N connector
  • Specially designed for EMC applications
  • Measurement of continuous average power
  • 90 dB dynamic range for CW and modulated signals
  • Low sensitivity to harmonics

Brief Description In EMC applications, usually only the average power is of interest. This is where the R&S®NRP-Z91/R&S®NRP-Z92 average power sensors are the perfect fit. They cover measurement ranges that are used in radio telecommunications (up to 6 GHz) as well as the important lower frequency bands (down to 9 kHz). Users benefit from the excellent properties of the three-path diode power sensors, including a dynamic range of up to 90 dB, very low influence of the modulation on the measurement and outstanding impedance matching.
