R&S®NRP-Z91 Average Power Sensor

Accurate average power measurements for EMC applications

This is a discontinued product
Please note the following successor product(s):

Key Facts

  • Measurement range: -67 dBm - +23 dBm
  • Frequency range: 9 kHz to 6 GHz
  • N connector
  • Specially designed for EMC applications

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.

R&S®NRP-Z91, N connector 9 kHz to 6 GHz
R&S®NRP-Z92, N connector 9 kHz to 6 GHz

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.
