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). With 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.
Key Facts• Measurement range: -57 dBm - +33 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
Supported DevicesThe R&S®NRP-Z92 sensor can be connected to latest-generation of signal generators, spectrum analyzers and network analyzers. This allows you to directly display the average power measured with the sensor without the need for an R&S®NRP2 base unit or PC. This also provides a simple solution for automatic level correction in a signal generator. The spectrum analyzers use the measured power as an absolute reference for increasing the measurement accuracy.
