Rohde & Schwarz NRP-Z Power Sensors

The R&SŪNRP-Z smart sensors offer innovative multi-path sensor technology. These sensors are intelligent, standalone instruments that combine either with the R&SŪNRP basic unit or with a PC/laptop via an optional USB interface and R&S software, making them the smallest and most lightweight microwave measuring instruments available.

Key Features and Specifications

• High dynamic range of 90 dB
• High measurement accuracy and speed
• Intelligent R&S® Smart Sensors - plug in and measure
• Operation of sensor directly from PC via USB interface
• A single sensor can perform all the necessary measurements that typically require a variety of thermal, diode and peak sensors
• Multi-path architecture combining three diode detectors to obtain a large dynamic range for modulated signals

Three ways of displaying results with an R&S NRP sensor

As shown in the figure below, the NRP sensors can be used in connection with the R&S NRP base unit, but also directly connected to a PC via USB adapter:

Miniature power meter

The sensors of the R&S NRP-Z series can be used as standalone measuring instruments without the basic unit. In addition to the power sensor itself, they include a CPU that controls the sensor, processes the measurement results and operates the interface: a complete miniaturepower meter. All measurement data and settings are transmitted via a digital USB interface. This concept, with which Rohde & Schwarz already set the pace in the field of directional power meters, is now being used for the first time in classic microwave power measurements.

Use on a PC

The most cost-effective method for highprecision power measurements is to connect the sensors directly to a PC, especially if data acquisition and evaluation take place via a PC. The main area of application is production, since production environments usually include a process controller. The fact that the basic unit can be omitted saves space in the rack and reduces costs. Service technicians will also appreciate this option since the power meter fits into a trouser pocket and can easily be operated from a laptop.
