They combine excellent impedance matching with a sophisticated connector concept. The internal calibration test generates reliable and stable measurements. R&S®NRP power meter sensors are available as USB sensors and can also be controlled via LAN. The R&S®NRP power meter portfolio is ideal for production, R&D and calibration labs as well as installation and maintenance.

Outstanding performance for reference applications
Unparalleled linearity ideal for performing relative measurements

Thermal power sensors are used in complex measurement tasks whereaccuracy is vital. To improve measurement accuracy, theR&S@NRPXXT(N)/TWG(N) thermal power sensor hardware is designed tokeep measurement noise to a minimum and make the sensor immune tothermal environmental effects.Three times faster than comparablesolutions on the market with triggered measurements and > 500measurements/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 causedby multiple reflections at the source and power sensors.To minimizesuch reflections, all thermal power sensors in the R&SeNRP family areexcellently matched to high frequencies, reducing measurementuncertainty

R&S^®NRPxxTWG power sensors

Intelligent, LAN enabled power measurements
Remote monitoring via LAN over any distance

The LAN power sensors are ideal for remote monitoring applicationssuch as satellite systems or particle accelerators, where sensors areplaced at different points in the system. The LAN interface makes iteasy to overcome large distances between the various test points andthe control center.

Remote monitoring of LAN power sensors

Internal calibration test

Rohde & Schwarz has implemented a special verification function inR&SeNRPxxT(N)sensors.The function covers all essential signal pathcomponents.Using a test routine, sensor response to highly stableapplied DC power is measured and compared to the values from theprevious calibration.The result provides information about the powersensor functionality and accuracy.
