Dear Customer,

Your power meter is equipped with firmware version ≥ 03.00. A number of functions have been modified
since the printing of the manual, and the modifications are described in the following.

Battery operation

The R&S NRP-B3 option allows the R&S NRP to be operated independently of the AC supply.
The battery is automatically charged as soon as its residual capacity has dropped below 96% full

charge and the R&S NRP is connected to the AC supply.
A warning is displayed shortly before the battery is completely discharged. If the battery is fully

discharged, the R&S NRP automatically switches off to prevent any damage to the battery by over­discharging. In this case, the battery should be recharged as soon as possible.

The charge status of the battery is displayed in the Battery dialog window and symbolically in every
expanded window. The Ba ttery dialog window also provides i nformation about the battery's rem aining
operating time.

Supplement R&S NRP

1144.1400.12-04- Supplement 2 E-2

The data sheet specifies how long the R&S NRP can be operated from the battery. The battery
operating time depends on the number and type of the connected sensors and especially on the
brightness of the display backlighting.

The battery can be c harged at temperatures bet ween 5°C and 30°C and discha rged at temperatures
ranging from 0°C to 40°C. To prolong the life of the battery, however, the instrument should not be
operated too frequentl y at the upper l imit tem peratures. If the batter y is charged a t temper atures above
30°C, the charging proc ess is repeatedly interr upted to allow cooling, which considerabl y extends the
charging time. If the temperature exceeds a value of about 35°C, charging is practically discontinued.

It is normal that batter y char ging con tinues after the battery has been c har g ed 1 00 %. To prolong the life
of the battery, this process should not be aborted.

Since NiMH batteries ar e subject to considerable s elf-discharging, an R&S NRP that is equipped with
the R&S NRP-B3 option should n ot be stored for more than three m onths without being connecte d to
the AC supply.

Caution

The performance of a "Sm art Battery" may be manufacturer-s pecific. Only the original
battery will ensure cor rect functio ning and a char ging functiona lity that pro longs the life
of the option.

The safety test marks lose their validity if batteries from other manufacturers are used.

Calibrating the charge counter

From time to tim e, the battery must be calibrated so that th e remaining o perating tim e is not displa yed
incorrectly as a result of the battery's decreasing capacity over time. A calibration cycle can
automatically take place in normal operation, if the R&S NRP is fully discharged after being fully
charged, without intermittently connecting the instrument to the AC supply. In this case, no further
action on the part of the user is required.

However, if calibr ation is not perform ed in normal op eration, after som e time the battery wi ll request a
calibration cycle. This request will be displayed after the R&S NRP has been switched on.

Switch on the R&S NRP:

Request for a calibration cycle from the battery

R&S NRP Supplement

ä

The calibration cycle is performed. First of all, the battery is fully

charged, then fully discharged and finally fully charged again. This
process may take between 11 and 20 hours depending on the char ge
status of the battery at the beginning of the calibration cycle. The
higher the charge of the battery at the beginning, the faster the
calibration c ycle is performed. Calibr ation itself tak es place at the end
of the discharging process.

During the calibration c ycle, or at least un til the end of the dis charging
phase, the R&S NRP should remain connected t o the AC supply and
should always be on. Otherwise the calibration c ounter is not calibra­ted, which means that the warning will be displayed again when the
R&S NRP is switched on the next time.

The calibration c ycle is not performed. The warning will be displayed

again when the R&S NRP is switched on the next tim e.

Dear Customer,

Your power meter is equipped with firmware version ≥ 03.00. A number of functions have been modified
since the printing of the manual, and the modifications are described on the following pages.

Ethernet

For remote control via a TCP/IP- based LAN, t he R&S NRP can be fitted with an optio nal 10/100B aseT
Ethernet interfac e (option R&S NRP-B4). The soc ket is locat ed on the r ear panel of the R&S NRP. Via
this interface, a controller can remote-control the R&S NRP by means of the power meter's SCPI
commands, using the VX I11 protocol (TCP/IP instrum ent protocol specificatio n), version 1.0, released
on 17 July 1995 by the VXIbus Consortium.

VXI11

The VXI11 protocol uses ONC RPC (open network computing remote procedure calls), making it
possible to call R&S NRP functions at the source code level as if they were running locally on the
controller. The following figure shows the relationships of the relevant protocol layers in the OSI
reference model.

The VXI11 protocol stack in the OSI reference model

A VXI11 remote-c ontrol connection co nsists of three channels (core, a bort and interr upt) which can b e
used to set up as many link s as desired. The concept of link s makes it possible to connec t a network
instrument client in a controller with a num ber of logic al measur ement devices in a host com puter via a
single VXI11 remote-c ontr o l connec t ion. A li nk is then set up to each logical d ev ice. It is als o pos si ble t o
set up several links to one logical device, provided that several servers are running on the network
instrument host or a network instrument client is being served by several controllers. To prevent
problems caused b y several controllers s imultaneously accessing one device, li nks can be locked. A
locked link has exclusive access rights to a particular device. Accesses via other links are then not
possible. An exception is an abort via the abort cha nnel, which can be execut ed at any time and also
aborts the execution of commands via other links.

R&S NRP Supplement

1144.1400.12-04- Supplement 3 E-1

Communication channels of a VXI11 connection

Channel Meaning

Core All client-server communication, excluding aborts and i nterrupt s, is handled via this channel.

Abort Since the commands in the core channel are serialized and therefore cannot be interrupted,

asynchronous abort commands must be transmitted via a separate, independent channel. This
channel serves no further purpose.

Interrupt Service requests (SRQs) are reported to the network instrument client via this channel. As all links

share this channel, the client must subsequently determine which device triggered the SRQ by
polling the status bytes (device_readstb() function) of all connected devices.

Connection setup

A socket connection is set up f or each chan nel. All c omm ands via the c ore or ab ort channel c ontain a n
ID that is used t o ass i gn th e c om mand to a link. T he i nter rupt c han ne l, whic h is a ls o implemented using
sockets, is shared b y all links. Commands transm itted via this channel do not contain a li nk ID. The
setup is handled b y the net wor k ins tr um ent c lie nt, whic h first requests the conn ec tions f r om the net wor k
instrument server's por tmapper service at port 111. The por tmapper subsequently ac tivates the c h ann e l
in the R&S NRP and tells the client a t which por ts channe l services can be a ddress ed. For this reas on,
it is important that any firewalls or routers between the client and the R&S NRP enable free access from
the controller to the R&S NRP (core and abort channels) and vice versa (interrupt channel). As the
ports for the channels are d ynamically assigned, relia ble information regardin g the port numbers used
cannot be provided.

Remote control via VXI11

The following possibilities are suggested for remote-controlling the R&S NRP via VXI11:

1. The simplest way to create remote-control programs is by using a VISA (virtual instruments
software architecture) im plem entation and cre ating th e rem ote- control pr ogram s under Visu al Bas ic
or C/C++. VISA implem entations provide an application progr amming interface ( API) that offers all
necessary functions. Knowledge about VXI11 is helpful but not required.

The VISA resource identifier used to identify a VXI11 device has the following format:

TCPIP::<IP address>::IN STR

The IP address is specified using the familiar dot notation (e.g. 89.10.65.59).

2. T he "TCP/IP Ins trument Pr otocol Specif ication VX I11" conta ins in annex C an R PCL descript ion of
the protocol. The program rpcgen, which is contained in any ONC RPC distribution, is used to
generate stubs, which can be inserted into separate C programs, where the functions from the
following table can be called like ordinary library functions.

This procedure requires RPC programming skills.

VXI11 protocol functions

Function name Channel Meaning

create_link()

core Opens a link to a network instrument device, setting up socket connections for the

core and abort channels, but not for the interrupt channel.

destroy_link()

core Cancels a link to a network instrument device.

device_write()

core Sends an IEEE 488.2 or SCPI command as a string to a network instrument device.

device_read()

core Reads responses from a network instrument device.

device_readstb()

core Reads the status byte of a network instrument device.

device_trigger()

core Triggers a trigger in a network instrument device and is equivalent to *TRG.

device_clear()

core Triggers a "device clear" (DCL) in a network instrument device. In the R&S NRP,

DCL and abort have the same effect. Because device_abort(), unlike
device_clear(), is transmitted over the abort channel, it is not serialized with
other commands but goes directly to the device and is therefore preferable.

device_remote()

core Changes the network instrument device to the remote state.

device_local()

core Changes the network instrument device to the local state.

device_lock()

core LLO (local lock out). The keyboard of the network instrument device is locked.

device_unlock()

core Cancels the LLO state.

device_docmd()

core The network instrument device executes a command.

device_abort()

abort The network instrument device aborts an in-progress command.

See device_clear().

create_intr_chan()

core An interrupt channel to the network instrument device is set up.

destroy_intr_chan()

core An existing interrupt channel to the network instrument device is cleared down.

device_enable_srq()

core The sending of service requests from the network instrument device to the network

instrument controller is activated/deactivated.

device_intr_srq()

interrupt This is the only function that the network instrument server calls from the network

instrument device. It signals a service request (SRQ).

USB

If the R&S NRP is connected to a contr oll er via a USB 1.1 in terf ace, it logs o n as a USBTMC ( USB t est
and measurement class) device, provided that USB is selected as a remote interface in the
SystemÆRemote menu. The USBTMC stand ard d escribes how IE EE 488 .2-com patibl e communication
with can be implemented via USB.

As with remote contr ol via VXI11, the use of a VISA d istribution that m ust include a U SBTMC driver is
recommended for remote control via USB. The VISA resource identifier used to identify a USBTMC
device has the following format:

USB::<vendor ID>::<product ID>::<serial number>::INSTR

<vendor ID>

0x0aad

<product ID>

0x001b

<serial number>

The serial number is a string that can be found in the SystemÆSystem Info menu.

In addition, the VI S A res o u r c e ide ntif ier appears on th e R &S NR P d isplay if the USB rem ote int e rf ac e is

Basic safety instructions

1. The product may be operated only under
the operating conditions and in the
positions specified by the manufacturer. Its
ventilation must not be obstructed during
operation. Unless otherwise specified, the
following requirements apply to
Rohde & Schwarz products:
prescribed operating position is always with
the housing floor facing down, IP protection
2X, pollution severity 2, overvoltage
category 2, use only in enclosed spaces,
max. operation altitude max. 2000 m.
Unless specified otherwise in the data
sheet, a tolerance of ±10% shall apply to
the nominal voltage and of ±5% to the
nominal frequency.

2. Applicable local or national safety
regulations and rules for the prevention of
accidents must be observed in all work
performed. The product may be opened
only by authorized, specially trained
personnel. Prior to performing any work on
the product or opening the product, the

product must be disconnected from the
supply network. Any adjustments,
replacements of parts, maintenance or
repair must be carried out only by technical
personnel authorized by Rohde & Schwarz.
Only original parts may be used for
replacing parts relevant to safety (e.g.
power switches, power transformers,
fuses). A safety test must always be
performed after parts relevant to safety
have been replaced (visual inspection, PE
conductor test, insulation resistance
measurement, leakage current
measurement, functional test).

3. As with all industrially manufactured goods,
the use of substances that induce an
allergic reaction (allergens, e.g. nickel)
such as aluminum cannot be generally
excluded. If you develop an allergic
reaction (such as a skin rash, frequent
sneezing, red eyes or respiratory
difficulties), consult a physician immediately
to determine the cause.

Safety Instructions

1171.0000.42-02.00 Sheet 3

4. If products/components are mechanically
and/or thermically processed in a manner
that goes beyond their intended use,
hazardous substances (heavy-metal dust
such as lead, beryllium, nickel) may be
released. For this reason, the product may
only be disassembled, e.g. for disposal
purposes, by specially trained personnel.
Improper disassembly may be hazardous to
your health. National waste disposal
regulations must be observed.

5. If handling the product yields hazardous
substances or fuels that must be disposed
of in a special way, e.g. coolants or engine
oils that must be replenished regularly, the
safety instructions of the manufacturer of
the hazardous substances or fuels and the
applicable regional waste disposal
regulations must be observed. Also
observe the relevant safety instructions in
the product documentation.

6. Depending on the function, certain products
such as RF radio equipment can produce
an elevated level of electromagnetic
radiation. Considering that unborn life
requires increased protection, pregnant
women should be protected by appropriate
measures. Persons with pacemakers may
also be endangered by electromagnetic
radiation. The employer is required to
assess workplaces where there is a special
risk of exposure to radiation and, if
necessary, take measures to avert the
danger.

7. Operating the products requires special
training and intense concentration. Make
certain that persons who use the products
are physically, mentally and emotionally fit
enough to handle operating the products;
otherwise injuries or material damage may
occur. It is the responsibility of the
employer to select suitable personnel for
operating the products.

8. Prior to switching on the product, it must be
ensured that the nominal voltage setting on
the product matches the nominal voltage of
the AC supply network. If a different voltage
is to be set, the power fuse of the product
may have to be changed accordingly.

9. In the case of products of safety class I with
movable power cord and connector,
operation is permitted only on sockets with
earthing contact and protective earth
connection.

10. Intentionally breaking the protective earth
connection either in the feed line or in the
product itself is not permitted. Doing so can
result in the danger of an electric shock
from the product. If extension cords or
connector strips are implemented, they
must be checked on a regular basis to
ensure that they are safe to use.

11. If the product has no power switch for
disconnection from the AC supply, the plug
of the connecting cable is regarded as the
disconnecting device. In such cases, it
must be ensured that the power plug is
easily reachable and accessible at all times
(length of connecting cable approx. 2 m).
Functional or electronic switches are not
suitable for providing disconnection from
the AC supply. If products without power
switches are integrated in racks or systems,
a disconnecting device must be provided at
the system level.

12. Never use the product if the power cable is
damaged. By taking appropriate safety
measures and carefully laying the power
cable, ensure that the cable cannot be
damaged and that no one can be hurt by
e.g. tripping over the cable or suffering an
electric shock.

13. The product may be operated only from
TN/TT supply networks fused with max.
16 A.

14. Do not insert the plug into sockets that are
dusty or dirty. Insert the plug firmly and all
the way into the socket. Otherwise this can
result in sparks, fire and/or injuries.

15. Do not overload any sockets, extension
cords or connector strips; doing so can
cause fire or electric shocks.

16. For measurements in circuits with voltages
V

rms

> 30 V, suitable measures (e.g.
appropriate measuring equipment, fusing,
current limiting, electrical separation,
insulation) should be taken to avoid any
hazards.

17. Ensure that the connections with
information technology equipment comply
with IEC 950/EN 60950.

18. Never remove the cover or part of the
housing while you are operating the
product. This will expose circuits and
components and can lead to injuries, fire or
damage to the product.

Safety Instructions

1171.0000.42-02.00 Sheet 4

19. If a product is to be permanently installed,
the connection between the PE terminal on
site and the product's PE conductor must
be made first before any other connection
is made. The product may be installed and
connected only by a skilled electrician.

20. For permanently installed equipment
without built-in fuses, circuit breakers or
similar protective devices, the supply circuit
must be fused in such a way that suitable
protection is provided for users and
products.

21. Do not insert any objects into the openings
in the housing that are not designed for this
purpose. Never pour any liquids onto or into
the housing. This can cause short circuits
inside the product and/or electric shocks,
fire or injuries.

22. Use suitable overvoltage protection to
ensure that no overvoltage (such as that
caused by a thunderstorm) can reach the
product. Otherwise the operating personnel
will be endangered by electric shocks.

23. Rohde & Schwarz products are not
protected against penetration of water,
unless otherwise specified (see also safety
instruction 1.). If this is not taken into
account, there exists the danger of electric
shock or damage to the product, which can
also lead to personal injury.

24. Never use the product under conditions in
which condensation has formed or can form
in or on the product, e.g. if the product was
moved from a cold to a warm environment.

25. Do not close any slots or openings on the
product, since they are necessary for
ventilation and prevent the product from
overheating. Do not place the product on
soft surfaces such as sofas or rugs or
inside a closed housing, unless this is well
ventilated.

26. Do not place the product on heat­generating devices such as radiators or fan
heaters. The temperature of the
environment must not exceed the maximum
temperature specified in the data sheet.

27. Batteries and storage batteries must not be
exposed to high temperatures or fire. Keep
batteries and storage batteries away from
children. If batteries or storage batteries are
improperly replaced, this can cause an
explosion (warning: lithium cells). Replace
the battery or storage battery only with the

matching Rohde & Schwarz type (see
spare parts list). Batteries and storage
batteries are hazardous waste. Dispose of
them only in specially marked containers.
Observe local regulations regarding waste
disposal. Do not short-circuit batteries or
storage batteries.

28. Please be aware that in the event of a fire,
toxic substances (gases, liquids etc.) that
may be hazardous to your health may
escape from the product.

29. Please be aware of the weight of the
product. Be careful when moving it;
otherwise you may injure your back or other
parts of your body.

30. Do not place the product on surfaces,
vehicles, cabinets or tables that for reasons
of weight or stability are unsuitable for this
purpose. Always follow the manufacturer's
installation instructions when installing the
product and fastening it to objects or
structures (e.g. walls and shelves).

31. Handles on the products are designed
exclusively for personnel to hold or carry
the product. It is therefore not permissible
to use handles for fastening the product to
or on means of transport such as cranes,
fork lifts, wagons, etc. The user is
responsible for securely fastening the
products to or on the means of transport
and for observing the safety regulations of
the manufacturer of the means of transport.
Noncompliance can result in personal injury
or material damage.

32. If you use the product in a vehicle, it is the
sole responsibility of the driver to drive the
vehicle safely. Adequately secure the
product in the vehicle to prevent injuries or
other damage in the event of an accident.
Never use the product in a moving vehicle if
doing so could distract the driver of the
vehicle. The driver is always responsible for
the safety of the vehicle; the manufacturer
assumes no responsibility for accidents or
collisions.

33. If a laser product (e.g. a CD/DVD drive) is
integrated in a Rohde & Schwarz product,
do not use any other settings or functions
than those described in the documentation.
Otherwise this may be hazardous to your
health, since the laser beam can cause
irreversible damage to your eyes. Never try
to take such products apart, and never look
into the laser beam.

funcionamiento).

3. Como en todo producto de fabricación
industrial no puede ser excluido en general
de que se produzcan al usarlo elementos
que puedan generar alergias, los llamados
elementos alergénicos (por ejemplo el
níquel). Si se producieran en el trato con
productos R&S reacciones alérgicas, como
por ejemplo urticaria, estornudos frecuentes,
irritación de la conjuntiva o dificultades al
respirar, se deberá consultar inmediatamente
a un médico para averigurar los motivos de
estas reacciones.

4. Si productos / elementos de construcción son
tratados fuera del funcionamiento definido de
forma mecánica o térmica, pueden generarse
elementos peligrosos (polvos de sustancia
de metales pesados como por ejemplo
plomo, berilio, níquel). La partición elemental
del producto, como por ejemplo sucede en el
tratamiento de materias residuales, debe de
ser efectuada solamente por personal
especializado para estos tratamientos. La
partición elemental efectuada
inadecuadamente puede generar daños para
la salud. Se deben tener en cuenta las
directivas nacionales referentes al
tratamiento de materias residuales.

5. En el caso de que se produjeran agentes de
peligro o combustibles en la aplicación del
producto que debieran de ser transferidos a
un tratamiento de materias residuales, como
por ejemplo agentes refrigerantes que deben
ser repuestos en periodos definidos, o
aceites para motores, deberan ser tenidas en
cuenta las prescripciones de seguridad del
fabricante de estos agentes de peligro o
combustibles y las regulaciones regionales
para el tratamiento de materias residuales.
Cuiden también de tener en cuenta en caso
dado las prescripciones de seguridad
especiales en la descripción del producto.

6. Ciertos productos, como por ejemplo las
instalaciones de radiación HF, pueden a
causa de su función natural, emitir una
radiación electromagnética aumentada. En
vista a la protección de la vida en desarrollo
deberían ser protegidas personas
embarazadas debidamente. También las
personas con un bypass pueden correr

peligro a causa de la radiación
electromagnética. El empresario está
comprometido a valorar y señalar areas de
trabajo en las que se corra un riesgo de
exposición a radiaciones aumentadas de
riesgo aumentado para evitar riesgos.

7. La utilización de los productos requiere
instrucciones especiales y una alta
concentración en el manejo. Debe de
ponerse por seguro de que las personas que
manejen los productos estén a la altura de
los requerimientos necesarios referente a
sus aptitudes físicas, psíquicas y
emocionales, ya que de otra manera no se
pueden excluir lesiones o daños de objetos.
El empresario lleva la responsabilidad de
seleccionar el personal usuario apto para el
manejo de los productos.

8. Antes de la puesta en marcha del producto
se deberá tener por seguro de que la tensión
preseleccionada en el producto equivalga a
la del la red de distribución. Si es necesario
cambiar la preselección de la tensión

para el funcionamiento a tomas de corriente
de contacto de seguridad y con conductor
protector conectado.

10. Queda prohibida toda clase de interrupción
intencionada del conductor protector, tanto
en la toma de corriente como en el mismo
producto ya que puede tener como
consecuencia el peligro de golpe de corriente
por el producto. Si se utilizaran cables o
enchufes de extensión se deberá poner al
seguro, que es controlado su estado técnico
de seguridad.

11. Si el producto no está equipado con un
interruptor para desconectarlo de la red, se
deberá considerar el enchufe del cable de
distribución como interruptor. En estos casos
deberá asegurar de que el enchufe sea de
fácil acceso y nabejo (medida del cable de

1 Putting into Operation

This Chapter describes putt ing i nto op erati on ( un packing, AC supply connection, s witchin g the meter on
and off), function testi ng and installing the m eter, the preset or defau lt settings and also c ontains front
and rear views of the meter.

Notes on putting into operation

Before putting the R&S NRP into operation, ensure that

• the sensor inputs are not overloaded,

• the meter’s outputs are not overloaded or wrongly connected,

• the ventilation holes are not obstruc ted.

The meter may be damaged if these precautions are not observed.

Unpacking the meter

When you have removed t he meter from its packing, check that nothing is missing using the deliver y
note and the accessory lists.

If there is any damage, contact the c arrier. Keep all the packing to suppor t any claims for compensa­tion.

It is also best to use the original packing if the meter has to be shipped or transported at a later date.

Caution

If the meter is rack-mounte d ensure there is a free flow of air through the h oles in the
side panels.

The R&S NRP can be installed in 19" racks using a variet y of rack adapters (see data sheet f or order
Nos.). The installation instructions come with the adapter.

AC supply vo ltage

The R&S NRP can be operated f rom AC lines wit h a voltage r ange of 10 0 V to 240 V and a fr equenc y
range of 50 Hz to 60 Hz. Note that a restric ted voltage range (100 V to 120 V) appl ies to 400 Hz net­works. The AC supply connec tor is at the rear of the meter. The meter sets itself automatically to the
applied voltage if it is in range.

AC supply fuses

The R&S NR P has two fuses as indicated b y the type plate. The fuses are accomm odated in a fuse
holder in the AC supp ly connector. The h older can b e pulled out to i nsert fuses . The power supp ly has

saved are lost as a result of this procedure.

Resetting and setting brightness and contrast

If you press the (Æ) key immediatel y after s witchi ng on the
R&S NRP, after about 3 s e conds th e R &S NRP g oes into a
state in which you can adjust brightness and contrast.

Initially, contrast and brightness are automatically set to
their default values. You can then make the settings you
want using the diagram on the screen.

ON state

Whenever the meter is switched off, its settings are saved. The next tim e it is switched on, these set­tings are automatically restored.

If the last setup befor e switch-off is to be restored, the R&S NRP must be switched of f
with the standby key ( Ø ). If the met er is tur ned off by dis conn ec tin g the A C s upp l y, it is
possible that the settings being used immediately beforehand are not saved.

2 Getting Started

This Chapter contains step -by-step instructio ns for simple measur ements and provides an introd uction
to the R&S NRP's basic modes of oper atio n. Each s tep is lis ted in ord er . The operating steps that are to
be performed are highlig hted in grey, while the sections between c ontain screenshots and also com­ments and references to more information.

The five sections describe the following:

) Measuring average power

Step-by-step introduction to standard power measure­ments with the R&S NRP.

) Window handling (p. 2.11) and
) Setting measurement functions

(p. 2.16)

Basic techniques for configuring measurement windows.

) Graphically representing power

versus time (Scope mode),

Graphical representation of the time characteristic.

) Measuring av. burst power

(Burst Av mode), p. 2.21

Measurement of burst power without external triggering.

) Measuring average power in de-

fined time interval, p. 2.22

Power measurem ent in one or m o re suc cess ive tim eslots
with internal or external triggering.

Some of the sections later on in this Chapter assume familiarity with the basic operating techniques
which are introduced in the firs t two sections. It is , therefore, ad visable to go thr ough the firs t two sec­tions before considering other topics.

Requirements

• Read the notes on putting the meter into operation in Chapter 1.

• A single-c hannel R&S NRP is sufficient for m ost of the examples used in the s equel. However, if

you want to work through all t he steps in the section ) Set ting measurement functions (p. 2.16),
you will need a dual-channel ins tr ument.

• An R&S NRP-Z1x or R&S NRP-Z2x sensor is requir ed f or the sec tion ) Measuring av. b urst po wer
(Burst Av mode) (p. 2.21); all other sections can be worked through with the Thermal Sensors
R&S NRP-Z5x.

• A signal source is required for the m easurements that ar e described. It is bes t to use a signal ge n-
erator whose level c an be adjusted. If a generat or of this type is not a vailable, th e R&S NRP’s inte­gral power reference (option R&S NRP-B1) can be used instead.

3 Manual Operation

This Chapter describes the controls, displays, etc, the screen layout and how to operate the R&S NRP.

Keys

Keys on the front panel of the meter are used to manuall y operate the instrument. There are se veral
groups of keys, each group having a different function:

Softkeys

The six softkeys are rock er switches – in other words, they
can be “rocked” backwards and forwards by pressing on
the right or left side of the key.
The softkey functio n is c ont ex t-s ens iti ve and is indicated by
screen labelling.

For more information on the softke ys see  Men u ha ndl ing
on p. 3.7 and  Dialog boxes and their control elements on
p. 3.8.

Hardkeys

F R E Q

P R E S E T

( )

Z E R O C A L

/

The hardkeys are a direc t way of activating th e main func­tions and are always available for use:

• Brightness/contrast

• Frequency entry

• Preset and setups

• Zeroing

For further inform ation on using the h ardke ys, see Chapter
4, section "Hardkeys".

Cursor keypad

The cursor-key functions are context-sensitive. They can
be used to

• Select the menu,

• Select the active window,

• Move the cursor in text boxes,

• Change the value of an entry in a text box,

• Select an element from a drop-down list,

• Adjust the brightness and contrast of the display.

With the exception of m oving the cursor, the functions re­ferred to above can also be activated using softkeys.

Keys R&S NRP

1144.1400.12 3.2 E-2

Enter / MENU key

M E N U

As the (¶) key (i.e. Enter ke y), it is used to c onf irm entr ies
in text fields and dialo g boxes and to confirm selections in
the drop-down lists.

As the (MENU) key, it is used to fold out and f old back the
menus next to the softkeys.

The function of the ke y is determined according to context
– in other words, the Enter or MENU function is always
selected automatically for the operator by the instrument.

ESC / LOCAL

E S C

L O C A L

/

This key is use d as an (ESC) ke y to escape f rom the entry
mode in text boxes a nd drop-down lists. It is also us ed to
close dialog boxes and menus without losing any entries
that have been made ( Title bar on p. 3.8).

As the (LOCAL) k ey, it is used to s witch the R&S NRP from
remote control mode (all controls disabled) to manual
mode.

The key is automatic ally assigned its f unction according to
context – in other words, th ere is no m anual as signm ent by
the operator.

DEL / 1 TRIG

T R I G

D E L / 1

The (DEL) k ey is used to delete numbers or text in a field
so that a completely new entry can be made.

As the (1 TRIG) k ey, it triggers single-shot m easurements
in the Scope mode.

The function of the k ey is selected a utomaticall y according
to context.

R&S NRP Screen layout

1144.1400.12 3.3 E-2

Screen layout

Window

The R&S NRP displays results in windows. A maximum of
four windows can be displayed simultaneously on the
screen. They are numbered 1 to 4. Windows have a title
bar which contains the nu mber (not user-assignab le) and a
name (user-selectable) for the window.

Windows do not have any control elements.

Menu bar


active menu

A menu bar is alwa ys displayed at the top of the screen. It
contains the names of the R&S NRP’s menus.

One of these names is alwa ys in inverse video and this is
the name of the active menu.

Menu selection





The menu you want to activate can be selected by pressing
the right- or left-ha nd side of the to pm ost r ocker switc h one
or more times.

Alternatively you can also use the cursor keys (ê) (û).

Folding menus out or back

(¶ MENU) folds out the active menu.
The usual PC conventi on is not f ollowed – instea d of drop-

ping down directl y below the menu name in the m enu bar,
menus fold out to the r ight-hand edge of the screen. T his
means that the m enu items are directly next to the r ocker
switches used to select them.

If you press the (¶ MENU) key again, the menu folds back.
The menu also folds out automaticall y if another menu is

selected.

side of the rocker switch.

Softkeys with dual assignments

Close | Expand ( )

Some softkeys are assigned two menu items. One is se­lected by pressing the lef t-hand side of the rocker switch,
the other, the right-hand side.

The two menu items are separated by a vertical line.

Dialog boxes and their controls R&S NRP

1144.1400.12 3.8 E-2

Dialog boxes and their controls

Dialog boxes contain chec k boxes, opti on fields, editi ng fields and dro p-down lists as control elem ents.
They are activated using the appr opriate rocker switch to their right. If two control elements are posi­tioned side by side, the e lement on the lef t is operated with th e left-hand sid e of the rocker s witch and
the element on the right with the right-hand side of the rocker switch.

Title bar

Dialog boxes have a title bar which displays the name of
the dialog box and the [¶] symbol which is a reminder that
the dialog box can be closed with the (¶ MENU) key.

Caution: Settings made in dialog boxes are immedi-

ately set on the R&S NRP – in other words
you do not need to clos e the dialog box to ac­tivate the settings in the box.

Dialog boxes with tabs

Channel-specific s ettings are made in a special page in a
super-ordinate dialog box . In the top row of the dialog box,
there are tabs which you can use to switch between pages.

Channels which do not have a sensor connected and
channels that have not been installed are shown in grey
and cannot be selected.

Check boxes

Check boxes are used to activate and de-activate func­tions. You can toggle between the two states by pres sing
the appropriate softkey.

Option fields

Option fields contain groups of mutually exclusive operat­ing modes.

When you press the left-ha nd side of the roc ker switch , the
next option on the left is selected. When you press the
right-hand side of t he rocker switc h, the next o ption on the
right is selected.

In the

System I/O dialog box, option fields are assigned to

only one side of a roc ker switch. It is theref ore only possi­ble to scroll through in one direction.

Editing fields

Entry active

Not active

Editing fields are us ed to e nter or modify numbers and tex t.
The editor is acti vated by pressing the appropr iate rocker
switch — or the appropriate side of the rocker switch if
there is a dual assignment.

Editing can be performed in overwrite mode, in dicated by
the marked char acter being in in verse video. Mo difications
can be made either with the (ô) (â) curs or keys or nu­meric/digit softkeys which are provided in a digit or letter
panel when the editor is activated.

The (ê) (û) cursor keys are used to sel ect the d igit to be
edited.

R&S NRP Dialog boxes and their controls

1144.1400.12 3.9 E-2

Editing fields (cont.)

In the editing fields for quantities with units, the left/right
cursor keys can be use d to selec t the un it too; t he up/ down
cursor keys are used to edit it. Us ually, the dig it panel also
contains a unit softkey which you can use to change the
unit whenever you want.

If you want to make a completel y new entr y, the wh ole f ield
can be cleared with the (DEL/1TRIG) key. In the insert

mode (indicated by the

Ι cursor), you can enter digits

and/or letters.
Any changes you make to a field c an be conf irm ed with the

(¶ MENU) ke y. When this k ey is pressed , the ne w value is
subjected to a validity check. If the check discovers an
error, a warning message is output.

You can quit the editor by pressing the (ESC) key; this
leaves the old values unchange d. Any warning messages
are cleared.

 Tip

To set the maximum or minimum value permitted for a
parameter, first m ove the insertion mark to the left edge of
the entry field b y using the (û) key. Then press the (â)
key (several times if necessary) to set the maximum per­missible valu e or the (ô) key to set the mimimum permis­sible value.

Editing fields with direct entry of val­ues

The Filter, Range, Trigger and Trigger Advanced dialog
boxes are designed such that you can read the values
even when the dialog box is open.

If you edit a value in a dialog box using the cursor keys
(ô) (â), the new value is accepted immediately when
you press a ke y. This feature allows you to quickly as sess
the effect of editing and to perform interactive adjustment.

If you enter a new value with the letter panel (see belo w),
however, the symbol [¶] appears ab ove the editing field
to indicate that the new value is not accepted until you
confirm it with the (¶ MENU) key.

Dialog boxes and their controls R&S NRP

1144.1400.12 3.10 E-2

Digit and letter panels

Panels which are displayed when an editing field is acti­vated (see above) are used to enter digits, letters and
units.

Entering letters with t he letter panel is like enter ing letters
on a phone ke ypad. The Caps key is use d to select upper
case for the next letter.

Caution! To edit the Trig ger Delay, you must s elect the

unit by means of the cursor keys (see above).

Drop-down lists

Drop-down lists are used to select an item from an “a la
carte” list. When the drop-down list is activated, the list
“folds out” upwards or downwards.

The up/down cursor keys, or one of the rocker switches
next to the list, are used to select items from folded out
pop-up menus. Confirm the selection with the (¶ MENU)
key or reject with the (ESC) key.

Window sizes and types

Results are displa yed in the m ain section of the scree n in windo ws. Windows c ome in three s izes: ha lf
height, quarter height and f ull height. In windows, values can be displa yed digitally or in a combined
digital and analog mode ( See Chapter 4, section "Dis playing measurem ent results", for instr uctions on
selecting these modes).

DIG window, full height

Analog window, full height

Scope window, full height

Scope window, half height

DIG window, half height

Analog window, half height

DIG window, quarter height

Analog window, quarter height

You can expand all opene d windows to full height by activa ting the

Expand function from the Windows

menu. In this state, the full-height windows can be displayed consecutively using the Window 1 2 3 4
menu item. The opened windo ws can be reduced to their previous sizes with th e

Arrange menu item.

Otherwise, it is not possibl e to change the size of the windo ws – the window size is determined by the
number of windows.

Test Measurement

The R&S NRP-Z power sensors are absolu tel y calibrated; a c alibra tion m eas urem ent after switching o n
the instrument is not nece ssary and also not planned. The sensors should be recalibrated in regular
intervals; for details on th is, please refer to the data sheet. However , overload, other damage or ex­treme operating conditions may cause the measurement uncertainty to exceed the specified values.

The option R&S NRP-B1 (sensor c heck source) makes it poss ible to check the reliabili ty of the sensor
by performing a test m easurement. In the case of sensors with a lead- in attenuator (pad) – R &S NRP­Z22, R&S NRP-Z23 and R&S NRP-Z24 – the test measurement can be m ade with or without an at­tenuator.

essential if the res ult exhibits f luctuations du e to modulat ion. W ith very
low frequency m odulation in particu lar, it is a goo d idea to set the si ze
of the sampling windo w so that it exactl y equ als the m odulat ion per iod,
so ensuring optimal display settling:

N = 1, 2, 3, …
This means that the m inimum theoretical meas urement time can only

be obtained with smoothing turned off.
The more modulati on periods f it into a sampli ng window, the less criti-

cal it is whether N is an integer or not. W ith smoothing on, about f ive
periods are enoug h to reduce f luctuations caus ed by m odulation to an
acceptable leve l – even if N is not a n integer. W ith more th an nine p e­riods, the fluctuations are imperc eptible. With smoothing of f, the situa­tion is much less favourabl e as instead of just f ive periods as many as
300 are required; the fluctu ations only complete ly disappear with m ore
than 3000 periods.

However, it is not advisab le to make the sampling window too wide by
selecting an excessively large N, as the intrinsic noise of the sensor
increases. To reduce dis play fluctua tions due to no ise, it is best to us e
the averaging filter. ( Filter / averaging, page 4.19)

Sampling Rate –

If a sensor contains a sam pling A/D converter, the sampling rate can

be adjusted to prevent alias ing effects for particular types of modula­tion signal. Aliasing can occur with some sensors because the sam­pling frequency is located within the video bandwidth, which means
that spectral components of the modulation signal can fall in th is fre­quency range. Changing the sampling rate will make the aliasing ef­fects disappear.

power.

If diode sensors from the R&S NRP-Z1x and R&S NRP-Z2x series are

Background information

Sampling window

As the sensor amplifiers use chopping, a measurement comprises at least two sampling windows and a sensor­specific deadtime of a few 100 µs. Samples at equal time intervals over the duration of a sampling window are
taken and a partial measurement result is formed from these samples. The partial measurement results of two
adjacent sampling windows are combined and the average is either output as the final result or is subjected to
further averaging as one of a number of intermediate results ( Filter / averaging, page 4.19).

In the remote control mode, the sampling window determines the minimum measurement time that can be
achieved (2 × sampling window + deadtime). However, there is no point in selecting sampling window times very
much smaller than 1 ms if, to reduce display noise, the averaging filter has to be used. Due to the unavoidable
deadtime of the order of a few 100 µs per sampling window, the measurement time does not drop in proportion to
the reduction in sampling window time. This may even mean that, to obtain a well-defined noise component in the
result, a greater measurement time overall is required, if a sampling window that is too small is selected.

Smoothing modulated signals

With smoothing turned off, the samples within a sampling window are given equal weighting and averaged, which
turns the instrument into an integrating device. As described above, optimal reduction of fluctuations in the meas­urement result due to modulation can be obtained, if the size of the sampling window is an exact integer multiple of
the modulation period. If this is not the case, modulation can have a considerable effect even if the sampling win­dow is many times greater than the modulation period. This situation can be improved considerably if the samples
are weighted (raised von-Hann window) before averaging. This is like video filtering and is exactly what happens
when smoothing is activated.

Background information

Dropout tolerance

The

Dropout parameter facilitates the clear identification of the burst end of modulated signals (e.g.

NADC). Without this parameter, the end of the burst might erroneously be detected within the burst
owing to the consid er ab le modulation-specific po wer drops of s uc h s igna ls.

Dropout is set at least for the

duration of modulation- dependent power drops within the burst; thus, the end o f the burst cannot be
detected until the set t ime has elapsed af ter the power has droppe d below the trigger t hreshold. If the
trigger threshold is exceeded again during the dropout time, the process restarts from the beginning.

• Trigger threshold and trigger event

• Trigger event, exclude intervals and measurement interval

• During the bur st the signa l frequentl y falls below t he trigger thres hold without the end of a burst be-

which means that the dropout time has not yet elapsed.

• During the dropo ut time indicate d below, the signa l no longer exc eeds the trigger thr eshold so that
the last falling slope in the burst is detected as the end of the burst.
