R&S®NRP-Z Sensors
for Power Meter R&S NRP
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:
How to connect power sensors
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.
