Using the R&S NRP‑Z power sensors with an R&S NRP2 or a compatible
Rohde & Schwarz instrument
A short overview of the usage of the power sensors with the R&S NRP2 base unit
or a compatible Rohde & Schwarz instrument is given in this manual:
●Chapter 6.5, "R&S NRP2", on page 32
●Chapter 6.6, "Compatible Instrument", on page 34

Overview of the R&S NRP‑Z power sensor types
The R&S NRP‑Z power sensors are highly accurate standalone measuring instru-
ments 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 differ-
ent types of R&S NRP‑Z power sensors are suitable for nearly every measure-
ment task:
●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 measure-
ment 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 solu-
tion 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 measure-
ment 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

Key Features
R&S®NRP-Zxx
10Getting Started 1176.8822.02 ─ 04
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.
●Power sensor modules
Developed for level calibration using the R&S FSMR measuring receiver.

4 Preparing for Use
This section describes the basic steps to be taken when setting up the R&S
NRP‑Z power sensors for the first time.
Risk of injury due to disregarding safety information
Observe the information on appropriate operating conditions provided in the
data sheet to prevent personal injury or damage to the power sensor. Read
and observe the basic safety instructions provided with the power sensor, in
addition to the safety instructions in the following sections. In particular, do
not open the casing of the power sensor.
Risk of electrostatic discharge
Protect the work area against electrostatic discharge to avoid damage to
electronic components in the modules. For details, refer to the general
safety instructions.
Risk of instrument damage due to inappropriate operating conditions
An unsuitable operating site or test setup can damage the power sensor
and to connected devices. Before switching on the power sensor, observe
the information on appropriate operating conditions provided in the data
sheet. In particular, ensure the following:
●The power sensor is dry and shows no sign of condensation.
●The power sensor is connected as described in the following sections.
●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 correctly connected and are not overloaded.

R&S®NRP-Zxx
12Getting Started 1176.8822.02 ─ 04
4.1 EMI Suppression
Electromagnetic interference (EMI) can affect the measurement results.
To suppress generated electromagnetic interference:
●Use suitable shielded cables of high quality. For example, use double-shielded
RF cables.
●Always terminate open cable ends.
●Note the EMC classification in the data sheet.
4.2 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 instrument. Make sure
not to discard the box and packing material.
Packing material and transportation
Always make sure that sufficient mechanical and electrostatic protection is
provided when transporting the power sensors.

Used to connect the power sensor to a device under test (DUT) or a signal gener-
ator.
Caused by their different frequency ranges, the R&S NRP‑Z power sensors have
different RF connectors. Also, for maximal measurement accuracy, the RF con-
nector must be tightened using a torque wrench with a specific nominal torque.
Refer to the operating manual of your R&S NRP‑Z power sensor for information
on your connector and the allowed nominal torque.
4.4 Connecting the R&S NRP‑Z Power Sensors
When connecting the R&S NRP-Z27/-Z28/-Z37/-Z98 sensors, there are
additional requirements to fulfill. Refer to the operating manual of the corre-
sponding sensor for a description on how to connect it.
4.4.1 Connecting the RF Connector of the R&S NRP‑Z Power
Sensors
Risk of damage to the center pin of the RF connector
When connecting the power sensor, always rotate only the union nut of the
RF connector. Do not rotate the sensor itself to avoid damage the center pin
of the connector.
1. Refer to the operating manual of your R&S NRP‑Z power sensor to find out
what kind of RF connector your sensor has and the recommended nominal
torque.
2. Insert the RF connector of the attenuator straight into the RF output of your
DUT. Do not tilt it.
