Rohde & Schwarz – NRP Single Channel Power Meter

Rohde & Schwarz – NRP Single Channel Power Meter


The NRP RF and Microwave Power Meter is suitable for research and development, production and mobile service as well as the analysis of broadband modulation signals of third-generation mobile radio. In research applications, the NRP excels with high measurement accuracy and a dynamic range of 90 dB. This applies to broadband signals of any modulation, including RF bandwidths beyond 100 MHz for wireless LAN. The NRP base unit accommodates up to 4 sensor heads, and displays all four measurement results at the same time. Alternatively, the sensors can be connected directly to a PC via USB interface. Applications in manufacturing test also benefit from the instrument’s high measurement speed, its ease of use, and remote controllability. The NRP is lightweight and robust, and operates over a wide temperature range. This makes the instrument an excellent choice also for installation, service and maintenance in the field.
