R&S®NRP8S Three-path diode power sensor

Functions and performance features
  • Fully characterized power sensors
  • Minimizing measurement uncertainty
  • Intelligent averaging function minimizes measurement time
  • Versatile measurement functions
  • USBTMC for easy system integration
  • Built-in trigger I/O port
  • Sensor status at a glance with status LED
  • Detachable cables for flexible operation

The power sensors come with various, detachable cables for connection to diverse display units. A screw connection is provided on the sensor end to prevent accidental loosening of the cable.

The R&S®NRP-ZKU USB interface cable can be used to connect a power sensor to a laptop/PC via the USB interface. This is an extremely space-saving and also costefficient solution that does not require a base unit. Two software tools – R&S®Power Viewer Plus and R&S®NRPV virtual power meter – are available to simplify sensor operation from a laptop/PC. These tools support all measurement functions implemented in the sensors.

Multiple options to operate the R&S®NRPxxS/SN, R&S®NRPxxT/TN and R&S®NRPxxA/AN power sensors

The R&S®NRP-ZK6 interface cable is intended for operating a power sensor on the R&S®NRX base unit. It can also be used for connecting the power sensor to diverse Rohde & Schwarz signal generators and signal and spectrum analyzers to enhance these instruments with a highperformance power meter.

Intelligent, LAN enabled power measurements
  • Each sensor available as LAN model
  • Remote monitoring via LAN over any distance

The LAN power sensors are ideal for remote monitoring applications, e.g. for satellite systems or particle accelerators, where sensors need to be placed at different points in the system. The LAN interface makes it easy to overcome large distances between the various test points and the control center.

Simultaneous, location-independent remote monitoring of multiple R&S®NRPxxSN/TN/AN power sensors using a web browser
  • Power supply via Power over Ethernet (PoE)
  • Built-in web GUI
R&S®NRPxxS/SN three-path diode power sensors
  • Ideal for universal applications
  • 93 dB dynamic range thanks to innovative three-path concept

The R&S®NRPxxS/SN power sensors use three separate diode paths, each operated in the optimum detector range. As a result, the average power can be determined with high accuracy independent of the modulation type. Measurement results are hardly affected by interfering signals or harmonics. The R&S®NRPxxS/SN power sensors therefore behave in a way similar to thermal power sensors but offer significantly higher speed. They provide up to 93 dB dynamic range with an excellent lower measurement limit of –70 dBm.

Innovative three-path concept

In contrast to conventional multipath technology, adjacent diode paths in the R&S®NRPxxS/SN power sensors overlap by 6 dB. All paths are continuously and simultaneously measured. The final measurement result is achieved by appropriately weighting the measurement results of all paths. This innovative approach ensures a smooth transition between measurement paths. Problems due to hard switching between the measurement paths, such as hysteresis effects, additional measurement delays and differential nonlinearity, are eliminated. The patented sensor architecture also improves the signal-to-noise ratio and increases measurement speed in the transition region.

  • Unprecedented measurement speed and accuracy even at low levels
  • More than 50 000 readings/s
  • 10 000 triggered measurements/s
