2 Key Features
The thermal waveguide 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.
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.

3 Preparing for Use
For information on safety, see:
●Chapter 1.1, "For Your Safety", on page 7
●Chapter 3.2, "Operating Conditions", on page 11
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 Important Aspects for Test Setup
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:
Important Aspects for Test Setup

Preparing for Use
R&S®NRPxxTWG
12User Manual 1178.8371.02 ─ 04
● 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.
3.4 Connecting to a DUT
For connecting the power sensor to a DUT, use the RF connector of the power sensor.
For details, see Chapter 4.1, "RF Connector", on page 17.
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.
180
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 17.

It is used as an input for signals if the trigger source parameter is set to EXTernal2. It
is used as an output for trigger signals if the sensor is operated in the trigger master
mode.
Further information:
●Chapter 7.5.2, "Triggering", on page 43
4.3 Host Interface
The host interface connector is used for establishing a connection between the power
sensors and a USB host or a supported Rohde & Schwarz instrument. For this pur-
pose, an external cable is needed. Two types of cables are available:
●R&S NRP‑ZKU cable with a USB connector, for connecting the power sensor to a
USB host device (R&S order number 1419.0658.xx).
●R&S NRP‑ZK6 cable with a push-pull type connector, for connecting the power
sensor to a base unit, R&S NRX or R&S NRP2, or other Rohde & Schwarz prod-
ucts with the round connector (R&S order number 1419.0664.xx).
These cables can be obtained in different lengths up to 5 meters.
4.4 Status LED
The status LED gives information about the state of the power sensor. The following
states are defined:
Indication State
White Idle state. The sensor performs no measurement and is ready for use.
Flashing white Firmware update is in progress
Slow flashing white Sanitizing in progress
Yellow Wait for trigger state

5.1 R&S NRP Toolkit
Before you start using the power sensor, it is recommended to install the R&S NRP
Toolkit.
The R&S NRP Toolkit is the basic software package that supplies low-level drivers and
tools for all power sensors. The components of the R&S NRP Toolkit depend on the
operating system.
5.1.1 Versions and Downloads
The R&S NRP Toolkit is available for the Microsoft Windows operating systems listed
under Chapter 5.1.2, "System Requirements", on page 19, Linux distributions and
MacOSX. Several R&S NRP Toolkit versions are available on your documentation CD-
ROM.
