For Your Safety
R&S®NRP Series
8Getting Started 1419.0170.02 ─ 10
2 For Your Safety
The R&S NRP series power sensor is designated for use in industrial, administrative,
and laboratory environments. Use the R&S NRP series power sensor only for its desig-
nated purpose. Observe the safety and usage instructions documented in the user
manual, as well as operating conditions and performance limits stated in the data
sheet.
The product documentation helps you to use the R&S NRP series power sensor safely
and efficiently. Keep the product documentation in a safe place and pass it on to the
subsequent users.
Safety information is part of the product documentation. It warns you about the poten-
tial dangers and gives instructions how to prevent personal injury or damage caused
by dangerous situations. Safety information is provided as follows:
●In the "Basic Safety Instructions", safety issues are grouped according to subjects.
For example, one subject is electrical safety. The "Basic Safety Instructions" are
delivered with the R&S NRP series power sensor in different languages in print.
●Throughout the documentation, safety instructions are provided when you need to
take care during setup or operation. Always read the safety instructions carefully.
Make sure to comply fully with them. Do not take risks and do not underestimate
the potential danger of small details such as a damaged power cable.

Key Features
R&S®NRP Series
9Getting Started 1419.0170.02 ─ 10
3 Key Features
The R&S NRP series power sensors are the successors of the established
R&S NRP‑Z series of RF power sensors.
They provide a high-speed USB interface that constitutes both the communication port
and the power supply connection.
Also, most sensors are available with an additional Gigabit Ethernet interface with
Power-over-Ethernet (PoE) power supply. The power sensors with networking capabili-
ties, the R&S NRP LAN power sensors, are marked with a trailing N in their names:
●R&S NRPxxSN
●R&S NRPxxAN
●R&S NRPxxTN
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.

4 Preparing for Use
For information on safety, see:
●Chapter 2, "For Your Safety", on page 8
●Chapter 4.2, "Operating Conditions", on page 10
4.1 Unpacking and Checking the Power Sensor
Check the equipment for completeness using the delivery note and the accessory lists
for the various items. Check the power sensor for any damage. If there is damage,
immediately contact the carrier who delivered the power sensor. Make sure not to dis-
card the box and packing material.
Packing material
Retain the original packing material. If the instrument needs to be transported or ship-
ped later, you can use the material to protect the control elements and connectors.
4.2 Operating Conditions
Risk of injury through hot surfaces
Applies only to the R&S NRP18S‑xx power sensors.
Under certain conditions, the maximum surface temperatures of the power sensor can
exceed the limits defined in EN 61010-1.
Provide protection against unintentional contact and wear appropriate personal protec-
tive equipment when touching the sensor.
Specific operating conditions are required to ensure accurate measurements and to
avoid damage to the power sensor and connected devices. Before switching on the
power sensor, observe the information on appropriate operating conditions provided in
the basic safety instructions and the data sheet of the power sensor.
In particular, ensure the following:
●The power sensor is dry and shows no sign of condensation.
●The ambient temperature does not exceed the range specified in the data sheet.
●Signal levels at the input connectors are all within the specified ranges.
●Signal outputs are connected correctly and are not overloaded.

4.3 Important Aspects for Test Setup
Handling the R&S NRP33SN-V power sensor
Risk of contamination
Always wear clean protective gloves when handling the R&S NRP33SN-V vacuum
power sensors to protect the device and its environment from contamination.
Recommended bake-out procedure
When the sensor is inserted in a vacuum chamber, perform vacuum baking for 100
hours at 85°C at a pressure lower than 10-5 mbar.
Preventing electrostatic discharge (ESD)
ESD is most likely to occur when you connect or disconnect a DUT.
►NOTICE! Risk of electrostatic discharge (ESD). Electrostatic discharge (ESD) can
damage the electronic components of the power sensor and the device under test
(DUT).
Ground yourself to avoid electrostatic discharge (ESD) damage:
● Use a wrist strap and cord, and connect yourself to the ground.
● Use a conductive floor mat and heel strap combination.
EMI impact on measurement results
Electromagnetic interference (EMI) may affect the measurement results.
To suppress generated electromagnetic interference (EMI):
●Use suitable shielded cables of high quality. For example, use double-shielded RF
and LAN cables.
●Always terminate open cable ends.
●Note the EMC classification in the data sheet.
4.4 Connecting to a DUT
For connecting the power sensor to a DUT, use the RF connector of the power sensor.
For details, see Chapter 5.1, "RF Connector", on page 22.
Connecting to a DUT

Preparing for Use
R&S®NRP Series
12Getting Started 1419.0170.02 ─ 10
Risk of overloading the sensor
Using a power sensor at a level above its upper measuring limit can damage the sen-
sor head. To avoid this risk, make sure not to exceed the test limit.
The test limits specified on the type label are valid only for the supplied attenuator. For
operation without attenuator, lower test limits apply, as specified in the data sheet.
To connect to the DUT
1. Ensure that the RF connector of your DUT is compatible with the RF connector of
the power sensor.
2. Insert the RF connector straight into the RF output of your DUT. Take care not to tilt
it.

3. NOTICE! Risk of damaging the center pin of the RF connector. Always rotate only
the hex nut of the RF connector. Never rotate the power sensor itself.
Tighten the RF connector manually.
4. To ensure maximum measurement accuracy, tighten the RF connector using a tor-
que wrench with the nominal torque recommended in Chapter 5.1, "RF Connector",
on page 22.
To disconnect from the DUT
►NOTICE! Risk of damaging the center pin of the RF connector. Always rotate only
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 sensor and
remove the sensor.
4.5 Connecting to a Computer
For operating the power sensor, you can choose from various possibilities. For details,
see Chapter 6, "Operating Concepts", on page 27.
