1 Welcome to the R&S NRPM OTA Power
Measurement Solution
The R&S NRPM OTA power measurement solution is designed to calibrate the trans-
mit antenna output power and test the beamforming function over the air. Applications
are in high frequency bands, used in modern high performance wireless system stand-
ards, e.g. 5G NR and IEEE802.11ay.
The R&S NRPM3 provides a USB high-speed host interface which constitutes both,
the communication port and the power supply connection. This new sensor module
and the specific antenna modules have been developed to provide measurements of
radiated RF power.
Key features
The R&S NRPM OTA power measurement solution features:
●OTA power measurements with up to three antenna module readings per
R&S NRPM sensor module
●Single and dual polarized antenna modules with integrated diode detector
●Very high sensitivity
●Fully calibrated system with specified system uncertainty
●Low-reflection antenna module
●Connection to a controller PC via USB
●Wide range of supported operating systems
●Easy operation with R&S NRP Toolkit and SCPI remote control.
About the R&S NRPM OTA power measurement solution
The power measurement solution consists of antenna modules, the three-channel sen-
sor module, and interface modules for connecting the antenna modules to the sensor
module. A PC measurement application controls the sensor module and the measure-
ment.
The single or dual-polarized antenna modules (R&S NRPM-A90, R&S NRPM-A90D)
are usually installed within an anechoic chamber, that can be:
●An RF test box, e.g. the R&S TS7124.
The antenna modules are positioned inside the RF test box, the sensor module is
outside. The sensor module is connected by the feedthrough module R&S NRPM-
ZD3 that provides the interface for up to three antenna modules.
Especially designed for use with the R&S TS7124, you can install up to six of the
feedthrough modules. An antenna ring inside the R&S TS7124 allows you to flexi-
bly position and align the antenna modules according to the application.
●An RF test chamber of larger dimensions, e.g. the R&S ATS1000 up to RF test
rooms.
The antenna modules and the sensor module are positioned inside the RF test
chamber. The interface module R&S NRPM-Z3, directly connected to the sensor
module provides the interface for up to three antenna modules.

Welcome to the R&S NRPM OTA Power Measurement Solution
R&S®NRPM
8User Manual 1425.8663.02 ─ 05
With the single and dual polarized antenna modules (R&S NRPM-A90, R&S NRPM-
A90D), you can calibrate the DUT (transmit antenna) output power and test the beam-
forming function.
The R&S NRPM measurement is controlled by an arbitrary user-definable measure-
ment application. For a quick startup, Rohde & Schwarz provides the free interactive
application R&S Power Viewer, which supports multiple sensor modules in the mea-
surement modes "Continuous Average (reliable average power)" and "Trace (display of
power versus time)".
The controller PC and the R&S NRPM3 communicate via a USB connection, using the
standardized protocol USBTMC. For the controller PC, the drivers and APIs are provi-
ded for the major operating systems Linux, Mac OS X, MS Windows. It is required that
you install a VISA driver on the host operating system, to use the I/O services provided
by this standardized software interface library.
The sensor module also supports SCPI remote control, e.g. to automate a measure-
ment with a scripting environment.

3 Preparing for Use
This section describes the basic steps to be taken when setting up the R&S NRPM
OTA power measurement solution 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 instrument. Read and observe the basic
safety instructions provided with the instrument, in addition to the safety instructions in
the following sections.
In particular, do not open the instrument casing.
Risk of electrostatic discharge (ESD)
Electrostatic discharge can quickly and imperceptibly damage or destroy the electro-
static sensitive antenna modules.
To prevent ESD, protect the work area against electrostatic discharge. Use an anti-
static wrist strap and cord and connect yourself to the ground, or use a conductive floor
mat and heel strap combination.
For details, refer to the general safety instructions.
Risk of antenna module damage when touching the PCB of the antenna modules
Never touch the exposed top or bottom of the antenna module PCB (printed circuit
board) during setting up. The PCB of the antenna module is sensitive. On contact, it
can be bent and lead to measurement inaccuracies.
Always hold the antenna modules by the housing.

Preparing for Use
R&S®NRPM
12User Manual 1425.8663.02 ─ 05
Risk of instrument damage during operation
An unsuitable operating site or test setup can damage the sensor module and connec-
ted devices. Make sure that the following operating conditions are met:
●The sensor module is dry and shows no sign of condensation.
●The sensor module is connected as described in the following sections.
●The ambient temperature does not exceed the permissible temperature 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.
3.1 EMI Suppression
Electromagnetic interference (EMI) affects the measurement results.
To suppress generated electromagnetic interference:
●Use only the cables provided for the R&S NRPM OTA power measurement solu-
tion.
●Always terminate open cable ends.
●Note the EMC classification in the data sheet.
Since the antenna module receives signals in a wide band, also outside the specified
frequency bands, perform the measurements always in a controlled EM environment.
In particular, when working with the R&S NRPM-Z3 interface module.
3.2 Unpacking and Checking the Instrument
Check the equipment for completeness using the delivery note and the accessory lists
for the various items. Check the equipment for any damage. If there is damage, imme-
diately 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 R&S NRPM components.

nal, and for working in trigger master-slave mode (optional), e.g. to synchronize sev-
eral sensor modules.

ful. Perform the firmware update again.
3.3.2 R&S NRPM-A90 and R&S NRPM-A90D Antenna Modules
This section introduces the antenna modules of the R&S NRPM OTA power measure-
ment solution.
