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

6.1.5 Performing a Firmware Update
Use the firmware update program (PureFW) to load new firmware for the power
sensors. It is part of the R&S NRP Toolkit that is supplied on a CD-ROM together
with the power sensors. For further details, refer to the operating manual.
6.2 R&S NRPV
The R&S NRPV enables you to measure power in all available measurement
modes. Also, you can use up to four power sensors simultaneously.
The R&S NRPV software can be installed on any Windows PC. It is provided on
your documentation CD-ROM and on the Rohde & Schwarz website as a separate standalone installation package. To make full use of its functionalities, you
must activate your R&S NRP‑Z power sensor with a license key.

2. On the PC, start the R&S NRPV software.
3. Connect the power sensor to the PC. For a detailed description, see Chap-
ter 5, "Connecting to a PC", on page 18.
4. If you use the power sensor for the first time with the R&S NRPV software,
activate the sensor using a license key:
a) In the "File" menu, select "File" > "Licensing".
The "Licensing NRP-Z Power Sensors for NRPV" dialog opens.
b) Select your power sensor.
c) Select "Enter License".
The "License Activation" dialog opens.
d) Enter the license key either manually or with the key code file.

e) Confirm with "OK" to return to the "Licensing NRP-Z Power Sensors for
NRPV" dialog. The dialog indicates all currently connected sensors.
Note: If you want to evaluate the R&S NRPV before buying a license for your
power sensor, you can activate a sensor for temporary use. To do so, select
"Evaluate Without License" in the "Licensing NRP-Z Power Sensors for
NRPV" dialog. For a detailed description, refer to the operating manual of the
R&S NRPV.
5. Switch on the test signal of the signal source.
6. To start a continuous measurement, select "Measure" > "Continuous".
The "Continuous" measurement window appears. It shows the measurement
results numerically, and the control panel for accessing further dialogs with
parameters for measurement, evaluation and display.
