Overview of the R&S NRPZ power sensor types
The R&S NRPZ 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 NRPZ 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
11Getting Started 1176.8822.02 ─ 06
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.

4.1 Unpacking and checking

1. Unpack the product carefully.
2. Retain the original packing material. Use it when transporting or shipping the
product later.
3. Using the delivery notes, check the equipment for completeness.
4. Check the equipment for damage.
If the delivery is incomplete or equipment is damaged, contact Rohde & Schwarz.

4.2 Choosing the operating site

Specific operating conditions ensure proper operation and avoid damage to the product and connected devices. For information on environmental conditions such as ambient temperature and humidity, see the data sheet.
13Getting Started 1176.8822.02 ─ 06
R&S®NRP-Zxx
Considerations for test setup
Electromagnetic compatibility classes
The electromagnetic compatibility (EMC) class indicates where you can operate the product. The EMC class of the product is given in the data sheet under "Gen­eral data".
Class B equipment is suitable for use in:
Residential environments
Environments that are directly connected to a low-voltage supply network
that supplies residential buildings
Class A equipment is intended for use in industrial environments. It can cause radio disturbances in residential environments due to possible conducted and radiated disturbances. It is therefore not suitable for class B environments. If class A equipment causes radio disturbances, take appropriate measures to eliminate them.
Preparing for use

4.3 Considerations for test setup

EMI impact on measurement results
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
Use high-quality shielded cables, for example, double-shielded RF and inter­face cables.
Always terminate open cable ends.
Ensure that connected external devices comply with EMC regulations.
Signal input and output levels
Information on signal levels is provided in the data sheet. Keep the signal levels within the specified ranges to avoid damage to the product and connected devi­ces.

Used to connect the power sensor to a device under test (DUT) or a signal gener­ator.
Caused by their different frequency ranges, the R&S NRPZ power sensors have different RF connectors. Also, for maximal measurement accuracy, the RF con­nector must be tightened using a torque wrench with a specific nominal torque.
Refer to the operating manual of your R&S NRPZ power sensor for information on your connector and the allowed nominal torque.
Preparing for use
4.5 Connecting the R&S NRPZ power sensor
When connecting the R&S NRP-Z27/-Z28/-Z37/-Z98 sensors, there are additional requirements to fulfill. Refer to the operating manual of the corre­sponding sensor for a description on how to connect it.

4.5.1 Connecting to a DUT

For connecting the power sensor to a DUT, use the RF connector. See "RF con-
nector" on page 16.
To connect to a DUT
1. Ensure that the RF connector of your DUT is compatible with the RF connec-
tor of the power sensor.
2. Inspect both RF connectors carefully. Look for metal particles, contaminants
and defects.
If either RF connector is damaged, do not proceed, because the risk of dam­aging the mating connector is too high.
3. Insert the RF connector straight into the RF output of your DUT. Take care not
to tilt it.

Tighten the RF connector manually.
5. Tighten the RF connector using a torque wrench with the nominal torque rec-
ommended in the operating manual of your R&S NRPZ power sensor to ensure maximum measurement accuracy.

4.5.2 Connecting to a host connector

You can use an R&S NRP‑Z3 or R&S NRP‑Z4 adapter.
To connect to an adapter
1. Rotate both cables, so that the red markings on the sleeves of both of them
are at the same position.
2. Insert the host connector of your sensor into the connector of your USB
adapter.
