2.2 Key features
The average power sensors are members of the R&S NRP series power sensors from
Rohde & Schwarz.
They provide a high-speed USB interface that constitutes both the communication port
and the power supply connection.
Also, most power sensors are available with an additional Gigabit Ethernet interface
with Power-over-Ethernet (PoE) power supply. The power sensors with networking
capabilities, the R&S NRP LAN power sensors, are marked with a trailing N in their
names:
●R&S NRPxxAN
The R&S NRP series power sensors are compatible with the R&S NRP‑Z power sen-
sors in both the interface (USB) and a common command subset. This compatibility
makes the replacement of the old power sensors easy.
For a detailed specification, refer to the data sheet and the brochure.

3.1 Unpacking and checking
1. Unpack the product carefully.
2. Retain the original packing material. Use it when transporting or shipping the prod-
uct 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.
3.2 Choosing the operating site
Specific operating conditions ensure proper operation and avoid damage to the prod-
uct and connected devices. For information on environmental conditions such as ambi-
ent temperature and humidity, see the data sheet.
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.
●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 radi-
ated disturbances. It is therefore not suitable for class B environments.
If class A equipment causes radio disturbances, take appropriate measures to
eliminate them.

R&S®NRPxxA(N)
14User Manual 1177.6017.02 ─ 08
3.3 Considerations for test setup
Give particular attention to the following aspects when handling power sensors.
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.
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a DUT.
►NOTICE! Electrostatic discharge can damage the electronic components of the
product and the device under test (DUT).
Ground yourself to prevent electrostatic discharge damage:
a) Use a wrist strap and cord to connect yourself to ground.
b) Use a conductive floor mat and heel strap combination.
3.4 Connecting to a DUT
For connecting the power sensor to a DUT, use the RF connector. See Chapter 4.1,
"RF connector", on page 26.
To connect to the DUT
1. Ensure that the RF connector of your DUT is compatible with the RF connector of
the power sensor.
See Table 4-1.
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.
See also Chapter 14.1, "Regular checks", on page 152.
3. Insert the RF connector straight into the RF output of your DUT. Take care not to tilt
it.

4. NOTICE! Risk of damaging the center pin of the RF connector. Only rotate the hex
nut of the RF connector. Never rotate the power sensor itself.
Tighten the RF connector manually.
5. Tighten the RF connector using a torque wrench with the nominal torque recom-
mended in Chapter 4.1, "RF connector", on page 26 to ensure maximum mea-
surement accuracy.
To disconnect from the DUT
1. NOTICE! Risk of damaging the center pin of the RF connector. Only rotate the hex
nut of the RF connector. Never rotate the power sensor itself.
Carefully loosen the union nut at the front of the RF connector of the power sensor.
2. Remove the power sensor.
3.5 Powering the power sensor
The electrical power for the R&S NRPxxA(N) is supplied over one of the following inter-
faces:
●Host interface
See Chapter 4.3, "Host interface", on page 27.
●LAN PoE interface
Available only for LAN power sensors. See Chapter 4.5, "LAN PoE interface",
on page 28.
If you use the Ethernet interface of the LAN power sensors, you have to provide the
electrical power by power over Ethernet (PoE). In this case, you cannot provide the
electrical power over the host interface instead.
Choose the PoE power sourcing equipment (PSE) with care
Only use PoE power sourcing equipment (PSE) as specified in the IEEE standards
802.3af or IEEE 802.3at. Otherwise, the following can happen:
●If too much power is supplied, the LAN power sensor can get overheated and
become damaged as a result.
●If the supplied power is not sufficient, the LAN power sensor does not work prop-
erly or not at all.

3.6 Connecting a cable to the host interface
For connecting the power sensor to a USB host, use the host interface. See Chap-
ter 4.3, "Host interface", on page 27.
Depending on the USB host, use one of the following cables:
●Computer or R&S NRP‑Z5 sensor hub:
R&S NRP‑ZKU cable with a USB connector
See Chapter 3.7.1, "Computer", on page 16.
●Base units or other supported Rohde & Schwarz instruments:
R&S NRP‑ZK6 cable with a push-pull type connector
See Chapter 3.7.2, "Base unit", on page 19.
These cables can be obtained in different lengths up to 5 meters. The order numbers
are provided in the data sheet.
To connect a cable to the host interface of the power sensor
1. Insert the screw-lock cable connector into the host interface connector of the power
sensor.
2. Tighten the union nut manually.
To disconnect the host interface of the power sensor
1. Loosen the union nut of the screw-lock cable connector.
2. Remove the cable.
3.7 Connecting to a controlling host
As a controlling host, you can use:
●Computer
●Base unit
For operating the power sensor, you can choose from various possibilities. For details,
see Chapter 5, "Operating concepts", on page 29.
3.7.1 Computer
If the controlling host is a computer, you can operate the power sensor in several ways.
For details, see Chapter 5, "Operating concepts", on page 29.
► Establish the connection using:
● Host interface
See Chapter 3.7.1.1, "Simple USB connection", on page 17.
See Chapter 3.7.1.2, "R&S NRP‑Z5 sensor hub setup", on page 18.

6. Connect the trigger input of the R&S NRP‑Z5 with a BNC cable to the trigger
source (optional).
7. Connect the trigger output of the R&S NRP‑Z5 with a BNC cable to the trigger
device (optional).
8. On the computer, start a software application to view the measurement results.
See Chapter 5, "Operating concepts", on page 29.
3.7.2 Base unit
As a controlling host, you can use an R&S NRX base unit.
You can also operate the power sensor using other supported Rohde & Schwarz
instruments with a sensor connector. For details, see also the user manual of the
instrument.
► Establish the connection with the base unit using:
● Host interface, see Chapter 5.7, "R&S NRX", on page 37.
● LAN interface, if:
– Base unit is an R&S NRX
– Power sensor is a LAN power sensor
See Chapter 3.7.3, "Using a LAN connection", on page 20.

3.7.3 Using a LAN connection
Requires a power sensor with networking capabilities, a LAN power sensor.
3.7.3.1 Connecting a LAN power sensor to the LAN
Depending on the available equipment, you can choose from different ways to connect
a LAN power sensor to a controlling host.
The Ethernet interface of a LAN power sensor requires PoE (power over Ethernet).
See Chapter 4.5, "LAN PoE interface", on page 28.
Electromagnetic interference (EMI) can affect the measurement results. To avoid any
impact, use category 5 cables or better.

1. NOTICE! Incorrectly connecting or disconnecting the power sensor can damage
the power sensor or lead to erroneous results. Ensure that you connect or discon-
nect the power sensor as described in Chapter 3.4, "Connecting to a DUT",
on page 14.
Connect the power sensor to the signal source.
2. NOTICE! Risk of sensor damage. Only use PoE power sourcing equipment (PSE)
as described in "Choose the PoE power sourcing equipment (PSE) with care"
on page 15.
