NRP-Z51

The R&S®NRP-Z51 thermal power sensor with its outstanding accuracy is suitable for very demanding reference applications independent of the signal modulation type.

Key Facts
• Measurement range: -35 dBm to + 20 dBm
• Frequency range: DC to 18 GHz
• N connector
• Operation with R&S®NRP2 base unit or via USB on a Laptop/PC
• Outstanding linearity of 0.007 dB (0.16%)    
• Industry-proven DC-coupled thermoelectric test cell
• Highly accurate continuous average power measurements
• Sophisticated connector design
• Excellent impedance matching

Supported Devices
The R&S®NRP-Z51 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.
