Features & benefits

Outstanding performance for reference applications

Unparalleled linearity ideal for performing relative measurements

Thermal power sensors are used in complex measurement tasks where accuracy is vital. To improve measurement accuracy, the R&S®NRPxxT(N)/TWG(N) thermal power sensor hardware is designed to keep measurement noise to a minimum and make the sensor immune to thermal environmental effects. Three times faster than comparable solutions on the market with triggered measurements and > 500 measurements/s in buffered mode.

**High precision measurements R&S®NRP67T**

Excellent impedance matching

From N to WR 6.5, always the right RF interface

Measurement uncertainty generally results from mismatches caused by multiple reflections at the source and power sensors. To minimize such reflections, all thermal power sensors in the R&S®NRP family are excellently matched to high frequencies, reducing measurement uncertainty.

Intelligent, LAN enabled power measurements

Remote monitoring via LAN over any distance

The LAN power sensors are ideal for remote monitoring applications, such as satellite systems or particle accelerators, where sensors are 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.

**Remote monitoring of LAN power sensors**

Internal calibration test

Rohde & Schwarz has implemented a special verification function in R&S®NRPxxT(N) sensors. The function covers all essential signal path components. Using a test routine, sensor response to highly stable applied DC power is measured and compared to the values from the previous calibration. The result provides information about the power sensor functionality and accuracy.
