Overview of the R&S NRP‑Z power sensor types
The R&S NRP‑Z power sensors are highly accurate standalone measuring instruments that offer all the functionality of conventional power meters, and more,
within the small housing of a power sensor. With a high dynamic range, the different types of R&S NRP‑Z power sensors are suitable for nearly every measurement task:
Key Features
●
Three-path power sensors
With patented three-path technology. Suitable for many applications, thanks to
their wide dynamic and frequency range. The sensors feature high measurement accuracy independent of the modulation type and speed and offer a
wide range of functions.
●
Two-path power sensors
With slightly modified dynamic range and performance. A cost-effective solution ideal for production applications.
●
Wideband power sensors
With high video bandwidth that permits accurate time-domain analysis of the
envelope power. Analysis is fast and easy thanks to also integrated measurement functions such as automatic pulse analysis.
●
Thermal power sensors
With outstanding measurement accuracy. They are the first choice for power
measurements in the frequency range from DC to 110 GHz as performed in
calibration labs, where measurement accuracy is the key requirement.
●
Average power sensors
Specially developed for EMC applications and cover the required frequency
range from 9 kHz to 6 GHz.
●
Level control sensors
9Getting Started 1176.8822.02 ─ 04
R&S®NRP-Zxx
With an integrated splitter that can split the signal into two parts of equal
power. This feature allows you to feed power to a device under test (DUT) and
monitor the power at the same time.
●
Power sensor modules
Developed for level calibration using the R&S FSMR measuring receiver.
