2.2 Key Features
The thermal 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 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 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 and the brochure.

3 Preparing for Use
For information on safety, see:
●Chapter 1, "Safety Information", on page 9
●Chapter 3.2, "Operating Conditions", on page 12
3.1 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.
3.2 Operating Conditions
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.
3.3 Considerations for Test Setup
Give particular attention to the following aspects when handling power sensors.
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).
Considerations for Test Setup

Preparing for Use
R&S®NRPxxT(N)
13User Manual 1177.6023.02 ─ 08
Ground yourself to avoid electrostatic discharge (ESD) damage:
● Using a wrist strap and cord, 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.
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 25.
Risk of overloading the sensor
Using a power sensor at a level above its upper measuring limit can damage the sen-
sor. To avoid this risk, make sure not to exceed the test limit.
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 4.1, "RF Connector",
on page 25.

14User Manual 1177.6023.02 ─ 08
To disconnect from the DUT
1. 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.
2. Remove the sensor.
3.5 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 26.
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, R&S order number 1419.0658.xx
See Chapter 3.6.1, "Computer", on page 15.
●Base units, R&S NRX or R&S NRP2, or other supported Rohde & Schwarz instru-
ments:
R&S NRP‑ZK6 cable with a push-pull type connector, R&S order number
1419.0664.xx
See Chapter 3.6.2, "Base Unit", on page 18.
These cables can be obtained in different lengths up to 5 meters.
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.

device (optional).
2. On the computer, start a software application to view the measurement results.
See Chapter 5, "Operating Concepts", on page 29.
3.6.2 Base Unit
As a controlling host, you can use an R&S NRX or R&S NRP2 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 39
See Chapter 5.8, "R&S NRP2", on page 40
● LAN interface, if:
– Base unit is an R&S NRX
– Power sensor is a LAN power sensor
See Chapter 3.6.3, "Using a LAN Connection", on page 18.
3.6.3 Using a LAN Connection
Requires power sensors with networking capabilities, the R&S NRP LAN power sen-
sors.
3.6.3.1 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.
Connecting to a Controlling Host

Preparing for Use
R&S®NRPxxT(N)
19User Manual 1177.6023.02 ─ 08
The Ethernet interface of a LAN power sensor requires PoE (power over Ethernet).
See Chapter 4.5, "LAN PoE Interface", on page 27.
Electromagnetic interference (EMI) can affect the measurement results. To avoid any
impact, use category 5 cables or better.

1. Connect the RF connector of the sensor to the DUT.
See Chapter 3.4, "Connecting to a DUT", on page 13.
2. NOTICE! Risk of sensor damage. Use only PoE power sourcing equipment (PSE)
according to IEEE standards 802.3af or IEEE 802.3at.
Otherwise your power sensor can get damaged.
Connect the RJ-45 Ethernet connector of the sensor to an Ethernet switch that
supports PoE power delivery.
3. Connect the controlling host to the Ethernet switch.
4. Establish a connection between the power sensor and the network.
See Chapter 3.6.3.2, "Establishing a Connection to the Network", on page 21.
