Most accurate power measurements for reference applications and use
in calibration labs
R&S®NRP power meter sensors have long been recognized for
supreme precision and speed. R&S®NRPxxT, R&S®NRPxxTN and
R&S®NRPxxTWG thermal power sensors are ideal for complex
measurement tasks where accuracy is vital. 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.
