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
Vrms > 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

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 heat-
generating 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

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

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.

R&S NRP-Z11/-Z21 Unpacking the sensor
1137.7406.12 1.1 E-2
1 Putting into Operation
Follow the instructions below precisely to prevent damage to the sensor – particularly
when you are putting it into operation for the first time.
Unpacking the sensor
Remove the sensor from its packing and check that nothing is missing. Inspect all items for damage. If
you discover any damage, inform the carrier responsible immediately and keep the packing to support
any claims for compensation.
It is also best to use the original packing if the sensor is to be shipped or transported at a later date..
The sensor contains components which can be destroyed by electrostatic discharges. To
prevent this happening, never touch the inner conductor of the RF connector and never
open the sensor.
Connecting the sensor
To prevent EMI, the sensor must never be operated with its enclosure wholly or partially
removed. Only use shielded cables that meet the relevant EMC standards.
Never exceed the maximum RF power limit. Even brief overloads can destroy the sensor.
In many cases, the RF connector only requires manual tightening. However, for maximal
measurement accuracy, the RF connector must be tightened using a torque wrench with a
nominal torque of 1.36 Nm (12" lbs.).
Connecting the sensor R&S NRP-Z11/-Z21
1137.7406.12 1.2 E-2
Operation with the R&S NRP basic unit
Connecting the sensor to the R&S NRP basic unit
The sensor can be connected to the R&S NRP basic unit when it is in operation. The interface
connector must be inserted, red marking upwards, into one of the R&S NRP basic unit’s sensor
connectors. When the sensor is connected, it is detected by the R&S NRP basic unit and initialized.
Connecting the sensor to the DUT
The Sensor R&S NRP-Z11/-Z21 has a male N connector and so can be connected to any standard
female N connector. Using light pressure, and keeping the male N connector perpendicular, insert it into
the female N connector and tighten the N connector locking nut (right-hand thread).
PC control
Hardware and software requirements
The following requirements must be met if the sensor is to be controlled by a PC via an interface
adapter:
• The PC must have a USB port.
• The PC’s operating system must support the USB port. This is the case with Windows™ 98,
Windows™ ME, Windows™ 2000, Windows™ XP and more recent versions of the Windows™
operating system.
• The USB device drivers in the supplied NRP Toolkit software package must be installed.
If these requirements are met, the sensor can be controlled using a suitable application program such
as the NrpFlashup program contained in the NRP Toolkit (includes the modules Power Viewer, USB
Terminal, Firmware Update and Update S-Parameters).
When you insert the CD-ROM supplied with the R&S NRP, the NRP Toolkit is automatically installed on
your PC. The rest of the procedure is self-explanatory.
The sensor can be powered in two ways:
• Self-powered from a separate power supply via the Active USB Adapter R&S NRP-Z3.
• Bus-powered from the PC or a USB hub with its own power supply (self-powered hub) via the
Active USB Adapter R&S NRP-Z3 or via the Passive USB Adapter R&S NRP-Z4.
As the sensor is a high-power device, there is no guarantee that it can be powered from all types of
laptop or notebook in the bus-powered mode. To be sure, you should determine the current at the USB
connectors beforehand:
R&S NRP-Z11/-Z21 Connecting the sensor
1137.7406.12 1.3 E-2
• In the Windows™ start menu, select Settings – Control Panel
• Select the System icon
• Select the Hardware tab
• By clicking on the button with that name, start the Device Manager
• Open USB Controller (all USB controllers, hubs and USB devices are listed here)
• Double-click on USB Root Hub or select Properties in the context menu (use the
right-hand mouse button)
• Select the Power tab (Fig. 1-1). If the hub is self-powered and the total power
available is, as indicated by Hub Information, 500 mA per port, high-power devices
can be connected.
Fig. 1-1 Displaying the total available power of a USB port
If you have any doubts, ask the manufacturer if the USB port on your laptop or notebook can handle
high-power devices.

Operation via the Active USB Adapter R&S NRP-Z3
Figure 1-2 shows the configuration with the Active USB Adapter R&S NRP-Z3, which also makes it
possible to feed in a trigger signal for the Timeslot and Scope modes. The order in which the cables are
connected is not critical.

Fig. 1-2 Configuration with Active USB Adapter R&S NRP-Z3
The plug-in power supply for the R&S NRP-Z3 can be powered from a single-phase AC source with a
nominal voltage range of 100 V to 240 V and a nominal frequency between 50 Hz and 60 Hz. The plug-
in power supply autosets to the applied AC voltage. No manual voltage selection is required.
The plug-in power supply comes with four primary adapters for Europe, the UK, the USA and Australia.
No tools of any kind are required to change the primary adapter. The adapter is pulled out manually and
another adapter inserted until it locks (Fig. 1-3).
Fig. 1-3 Changing the primary adapter
R&S NRP-Z11/-Z21 Connecting the sensor
1137.7406.12 1.5 E-2
The plug-in power supply is short-circuit-proof and has an internal fuse. It is not possible to replace this
fuse or open the plug-in power supply.
The plug-in power supply is not intended for outdoor use.
Keep within the temperature range of 0°C to 50°C.
If there is any condensation on the plug-in power supply, dry it off before connecting it to
the AC supply.

2 Virtual Power Meter
You will find the NrpFlashup program for controlling sensors with a PC under Windows™ on the
CD-ROM that accompanies the sensor. The program comprises several modules which can be started
centrally via the Windows™ start-menu entry NRP Toolkit.
This section describes the Power Viewer program module. This is a virtual power meter which only
uses a cut-down set of the sensor’s functions. This means that after an extremely brief familiarization
period, the user can measure the average power of modulated signals.
The other modules in NrpFlashup are described in Chapter 3 of the operating manual (Terminal and
Update S-Parameters modules) or in the service manual (Firmware Update module).
Overview
Start the virtual power meter using the NRP Toolkit – Power Viewer start-menu entry. The Power
Viewer program window is displayed (Fig. 2-1).

3 Manual Operation
The previous section describes the Power Viewer program module supplied with the instrument. This
module simplifies the most frequently used function of a power meter – measuring the average power of
an RF signal of almost any modulation. Other program modules are also part of the supplied equipment
and can be selected in the Start menu:
• Power Viewer: A detailed description of this virtual power meter module is provided in section 2.
• Terminal: Program module for sending commands and command sequences to the sensor and for
displaying measurement results, status information and other data from the sensor
• Firmware Update: Program module for updating the sensor firmware
• Update S-Parameters: Program module for loading an s-parameter table into the sensor
Program module "Terminal"
Main control elements
With the USB terminal, commands and command sequences can be sent to the sensor in two different
ways:
• Commands are entered in the Input field (Fig. 3-1). Consecutive commands can be entered as
separate lines, one below the other. The buttons associated with the Input field are described in
Table 3-1.
• Commands or command sequences are stored in command files. Command files are created with a
text editor, for instance, and then stored. They can be called as often as required (Fig. 3-2). The
buttons of the Command File field are described in Table 3-2.

Program module "Firmware Update" R&S NRP-Z11/-Z21
1137.7406.12 3.6 E-2
Program module "Firmware Update"
A detailed description of the program module for firmware updates is provided in the Service Manual.
Program module "Update S-Parameters"
Fundamentals
With the Sensor R&S NRP-Z11/-Z21 the influence of any twoport connected to the input on the
measurement result can be corrected by way of calculation. A precondition is that a complete set of s-
parameters of the twoport is available in the frequency range in question. The set of calibration data in
the R&S NRP-Z11/-Z21 therefore includes an s-parameter table with up to 1000 measurement
frequencies. The real and the imaginary part of each frequency as well as the uncertainty of
s-parameters 11
s, 12
s, 21
s and 22
s can be stored. Since the measurement frequencies in the
s-parameter table are independent of the calibration frequencies, they can be set so that the twoport
frequency range of interest is optimally covered. The real and the imaginary parts between these
measurement frequencies are linearly interpolated, while the more substantial measurement uncertainty
at the two neighbouring frequency points is used for calculating the uncertainty of the measurement
result. Below the first and above the last measurement frequency, the values of the first and the last
measurement frequency are used, respectively.
The NrpFlashup program (menu item Update S-Parameters) is used for loading an s-parameter table.
To ensure compatibility with a great number of network analyzers, NrpFlashup can process
measurement data files in S2P format. All standard frequency units (Hz, kHz, MHz, GHz) and display
formats (real and imaginary part, linear magnitude and phase, magnitude in dB and phase) are
supported. The only restriction is that a reference impedance of 50 Ω must be used for the
s-parameters. Other noise parameters in the measurement data file are not evaluated.
Structure of the S2P measurement data file:
1. The option line has the following format:
# [<frequency unit>] [<parameter>] [<format>] [<R n>]
# identifies the option line.
The <frequency unit> may be Hz, kHz, MHz or GHz. If a frequency unit is not specified, GHz is
implicitly assumed.
If a parameter is specified, S must be used in <parameter> for s-parameter files. If a parameter
is not specified, S is implicitly assumed.
The <format> may be MA (linear magnitude and phase in degree), DB (magnitude in dB, phase
in degree) or RI (real and imaginary part). If a format is not specified, MA is implicitly assumed.
R is optional and followed by the reference impedance in Ω. If an entry is made for R, R50 must
be specified. If no entry is made, R50 is implicitly assumed.
The option line should therefore read:
# [HZ | KHZ | MHZ | GHZ] [S] [MA | DB | RI] [R 50]
2. The measurement frequencies in ascending order are specified as follows:
() () () ()
iiiii fsfsfsfsf 22122111 ,
where
()
ijk fs is the specified display format for the option line.

1137.7406.12 3.7 E-2
3. Comments: Any line starting with an exclamation mark (!) is interpreted as a comment line.
To characterize the measurement uncertainty of the s-parameter test system, another data file can
optionally be created. Without this file, the measurement uncertainty cannot be correctly calculated in
the sensor. The syntax of the uncertainty data file is similar to that of the S2P data file but U is specified
as <Parameter> in the option line so that the option line reads # Hz U for frequencies in Hz.
The measurement frequencies must not be identical to those of the S2P measurement data files. In
most cases a few entries will be sufficient to characterize the measurement uncertainty of the s-
parameter test system. An s-parameter uncertainty as high as that of the neighbouring measurement
frequencies of the uncertainty data file is then selected. If different values are available, the higher one
is chosen. This is illustrated in the example below:
Table 3-4 Uncertainties of the s-parameter test system (example)
f in GHz unc [sik(f)]
0.1 0.01
1.0 0.01
1.1 0.005
10.0 0.005
10.1 0.01
40.0 0.01
Table 3-5 Interpolated uncertainties of measurement frequencies for s-parameters (example)

1.0 0.01
1.05 0.01
1.1 0.005
1.15 0.005
1.2 0.005
At 1.05 GHz, the higher uncertainty of the two adjacent 1.0 GHz and 1.1 GHz measurement
frequencies is entered in the s-parameter table. If an uncertainty of 0.005 is desired for all frequencies
above 1.0 GHz, the first measurement frequency in the uncertainty data file must above 1.0 GHz, e.g.
1.000001 GHz.
Program module "Update S-Parameters" R&S NRP-Z11/-Z21
1137.7406.12 3.8 E-2
Structure of the uncertainty data file:
1. The option line has the following format:
# [<frequency unit>] <parameter> [<format>] [<R n>]
# identifies the option line.
The <frequency unit> may be Hz, kHz, MHz or GHz. If a frequency unit is not specified, GHz is
implicitly assumed.
U must be specified for <parameter> in uncertainty data files. If a parameter is not specified, S
is implicitly assumed and as a result an error message is triggered.
<format> is ignored in uncertainty measurement files; the entry is therefore irrelevant.
R is optional and followed by the reference impedance in Ω. If an entry is made for R, R50 must
be specified. If no entry is made, R50 is implicitly assumed.
The option line should therefore read:
# [HZ | KHZ | MHZ | GHZ] U [MA | DB | RI] [R 50]
2. Measurement frequencies in ascending order are specified in the following form:
()
[]
()
[]
()
[]

[]
iiiii fsfsfsfsf 22122111 unc unc unc unc .
The s-parameters uncertainties are forwarded as follows:
• as extended absolute uncertainties ( 2=k) for the magnitude of reflection parameters 11
s
and 22
s, for instance 0.015,
• as extended uncertainties ( 2=k) in dB for the magnitude of transmission parameters 21
s
and 12
s, for instance 0.015.
3. Comments: Any line starting with an exclamation mark (!) is interpreted as a comment line.
Two additional values must be specified when the s-parameters are loaded: the lower and the upper
nominal measurement limit of the sensor-twoport combination. If s-parameter correction is active, these
values are transferred by the sensor in response to SYSTem:INFO? The values cannot always be
derived from the lower or upper measurement limit of the sensor alone and from the loss or gain of the
preconnected twoport. The upper measurement limit of the sensor-twoport combination may also be
limited by the twoport’s maximum power-handling capacity. Furthermore, the lower measurement limit
may be raised not only by the loss but also by the inherent noise of the twoport. For this reason,
NrpFlashup allows these values to be entered.
The upper nominal measurement limit of the sensor-twoport combination entered when
loading the s-parameters should be carefully specified, as automatic test systems may
evaluate it and an incorrect value may cause the sensor and/or the twoport to be
overloaded.
R&S NRP-Z11/-Z21 Program module "Update S-Parameters"
1137.7406.12 3.9 E-2
Procedure
To load an s-parameter table into the calibration set of the sensor, proceed as follows:
1. Connect the sensor to the USB port of the PC and start NrpFlashup.
2. Activate Update S-Parameters in the menu. The corresponding dialog window is opened (Fig.
3-3).
3. Under S-Parameter File enter the search path and the name of the S2P file containing the
parameters. Press the Browse... button to open a file-opening dialog where the S2P measurement
data file can be easily selected.
4. Under Uncertainty File enter the search path and the name of the measurement uncertainty file
containing the measurement uncertainty of the s-parameter test system. Press the Browse...
button to open a file-opening dialog where the measurement uncertainty file can be easily selected.
5. Enter the upper and lower nominal measurement limit of the sensor-twoport combination in the
Lower Power Limit and Upper Power Limit fields.
6. Enter a name for the loaded s-parameter set in the S-Parameter Device Mnemonic field. This
name can later be queried with SYSTem:INFO? "SPD Mnemonic" and is displayed on the NRP
basic unit when s-parameter correction is switched on.
7. Activate S-Parameter Correction on by Default if the SENSe:CORRection:TRANsmission switch
should be automatically set to ON when the sensor is put into operation.
8. Press Start for loading. (The dialog is closed with OK and the set parameters are retained. When
the dialog is exited with Cancel, all parameter modifications are ignored.)
Fig. 3-3 Dialog window for loading an s-parameter table
During loading, the current calibration data set of the sensor is overwritten. To be on the safe side, a
backup copy of the current calibration data set is therefore automatically stored before s-parameters are
loaded. The names of the backup files have the structure <batch number>_<date><time>.bak, where
<batch number> is the batch number of the sensor, <date> the date of the s-parameter update in
yymmdd format and <time> the time of the s-parameter update in the format hhmmss.
Store the automatically created backup files on a separate data medium (e.g. diskette,
CD-ROM or network drive) and, if required, assign an meaningful name to them to
simplify reloading. With the aid of these files, a previously used calibration data set of the
sensor can be restored.

1137.7406.12 3.10 E-2
To reload the backup file of a calibration data set into the sensor, proceed as follows:
• Press the Restore... button. The Restore S-Parameters window is opened (Fig. 3-4).
• Enter the search path and the name of the backup file in the Backup File field. Press the Browse...
button to open a dialog where the backup file can be easily selected.
• Press OK to start the restore procedure. (With Cancel the dialog window is exited without data
being restored).

6 Remote Control – Commands
Notation
In the following sections, all commands implemented in the sensor are first listed in a table according to
command systems and are then described in detail. The notation is largely in line with the SCPI
standard.
Command tables For a quick overview of available commands, the commands are listed in a table
before they are described. These tables contain the following four columns:
Command: Commands and their tree structure.
Parameters: Possible parameters.
Unit: The basic unit of the physical parameters (must not be sent with
parameters).
Remarks: Identification of all commands
• that have no query form
• that are available as query only
Indentations The various levels of the SCPI command hierarchy are shown in the table by
indentations to the right. The lower the level, the greater the indentation to the right.
It should be noted that the complete notation of the command includes the higher
levels too.
Example:
SENSe:AVERage:COUNt is represented in the table as follows:
SENSe first level
:AVERage second level
:COUNt third level
In the individual description, the command is shown in full length. An example of the
command is given at the end of the description.
[?]
?A question mark in square brackets at the end of a command indicates that this
command can either be used as a setting command (without question mark) or as a
query (with question mark). If the question mark is not in square brackets, the
command is a query only.
Example:
SENSe:POWer:AVG:APERture[?]
SENSe:POWer:AVG:APERture 1e-3 sets the length of the sampling window to
1 ms.
SENSe:POWer:AVG:APERture? Returns the currently set length as a response.
*IDN? Queries the sensor identification string that of course cannot be changed. For
this reason, this command is only available as a query.
Special
characters | for
parameters
A vertical bar between parameters is used to separate alternative options (OR link).
Example:
NITiate:CONTinuous OFF | ON
The parameter OFF or ON can be entered.
{numeric
expression} A numeric expression in braces means that it has been rounded to the nearest
integral value.
<parameter>
<variable> A parameter or a variable in triangular brackets expresses its current value.
Remote Control - Commands R&S NRP-Z11/-Z21
1137.7406.12 6.2 E-2
Commands as per IEEE 488.2
The sensor supports a subset of the possible setting commands and queries (Common Commands and
Queries) in line with IEEE 488.2.
*IDN? – IDentification Query
*IDN? returns a string with information on the sensor’s identity (device identification code). In addition,
the version number of the installed firmware is indicated. The string for a sensor of type R&S NRP-Z21
has the following structure:
ROHDE&SCHWARZ,NRP-Z21,<serial number>,<firmware version>
<serial number>: Serial number in ASCII
<firmware version>: Firmware version number in ASCII
*RST – Reset
*RST sets the sensor to the default state, i.e. the default settings for all test parameters are loaded.
*TRG – Trigger
*TRG triggers a measurement. For this purpose, the sensor is in the WAIT_FOR_TRIGGER state and
the source for the trigger event is set to BUS (TRIGger:SOURce BUS).
*TST? – Self Test Query
*TST? starts a selftest and returns 0 (no error found) or 1 (an error has occurred). The selftest
comprises the following functions:
• RAM test
• Operating voltages
• Temperature measurement
• Calibration data set
• Noise
• Zero-point offsets.
R&S NRP-Z11/-Z21 Remote Control - Commands
1137.7406.12 6.3 E-2
SCPI Commands
The sensors R&S NRP-Z11/-Z21 are controlled via the groups of commands
• CALibration (zeroing)
• SENSe (measurement configurations)
• SYSTem
• TRIGger
• SERVice.
CALibration
Table 6-1 Commands of the CALibration system
Command Parameter Unit Remarks
CALibration
:DATA[?] <calibration data set as definite length block>
:LENGth? Bytes Query only
:ZERO
:AUTO[?] OFF | ON | ONCE
CALibration:DATA[?] <calibration data set as definite length block>
CALibration:DATA is used for writing a calibration data set in the flash memory of the sensor.
The query yields the calibration data set currently stored in the flash memory as a definite length block.
CALibration:DATA:LENGth?
CALibration:DATA:LENGth? yields the length in bytes of the calibration data set currently stored in the
flash memory. Programs that read out the calibration data set can use this information to determine the
capacity of the buffer memory required.
Remote Control - Commands R&S NRP-Z11/-Z21
1137.7406.12 6.4 E-2
CALibration:ZERO:AUTO[?] OFF | ON | ONCE
The commands CALibration:ZERO:AUTO ON and CALibration:ZERO:AUTO ONCE zeroes the three
measurement paths of the sensor. For this purpose, the test signal must be deactivated or the sensor
disconnected from the signal source. The sensor automatically detects the presence of any significant
power to be measured. This causes zeroing to be aborted and error message NRPERROR_CALZERO
to be output. The CALibration:ZERO:AUTO OFF is ignored. Zeroing takes four seconds at a minimum,
but at least as long as the selected averaging filter needs for settling (only fixed-filter mode).
Repeat zeroing
• during warm-up after switching on or connecting the instrument
• after a substantial variation of the ambient temperature
• after fastening the sensor to an RF connector at high temperature
• after several hours of operation
• when very low-power signals are to be measured, e.g. less than 10 dB above the
lower measurement limit.
For zeroing switch off the test signal and do not remove the sensor from the signal source.
Apart from keeping the thermal balance, this has the advantage that the noise
superimposed on the test signal (e.g. from a broadband amplifier) can be detected on
zeroing and does not impair the measurement result.
The query always yields 1 (= OFF).
Default setting
After a power-on reset, the zero offsets determined during the last calibration are used until the first
zeroing. Therefore, very slight zero offsets are to be expected with a warmed up sensor. Initialization by
means of *RST or SYSTem:INITialize has no influence on the current zero offsets.

SENSe:AVERage:COUNt[?] 1 to 65536
SENSe:AVERage:COUNt sets the number of measured values that have to be averaged for forming
the measurement result in the modes Continuous Average, Burst Average and Timeslot. The higher this
averaging factor, the less the measured values fluctuate and the longer the measurement time lasts.
The parameter is rounded off to the nearest power-of-two number.
The query yields the averaging factor used in the modes Continuous Average, Burst Average and
Timeslot.
The averaging function must be activated with SENSe:AVERage:STATe ON so that the
set averaging factor becomes effective.
Default setting: 4
SENSe:AVERage:COUNt:AUTO[?] OFF | ON | ONCE
SENSe:AVERage:COUNt:AUTO activates (auto-averaging) or deactivates (fixed-filter mode) automatic
determination of the averaging factor in the modes Continuous Average, Burst Average and Timeslot. If
auto-averaging is activated, the averaging factor is continuously determined and set depending on the
level of power and other parameters.
SENSe:AVERage:COUNt:AUTO ON activates auto-averaging and SENSe:AVERage:COUNt
:AUTO OFF deactivates it. On deactivation, the previous, automatically determined averaging factor is
used in the fixed-filter mode. The SENSe:AVERage:COUNt:AUTO ONCE command ensures that a new
averaging factor is determined by the filter automatic function under the current measurement
conditions and used in the fixed-filter mode.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: OFF
Remote Control - Commands R&S NRP-Z11/-Z21
1137.7406.12 6.8 E-2
SENSe:AVERage:COUNt:AUTO:MTIMe[?] 1.0 to 999.99
SENSe:AVERage:COUNt:AUTO:MTIMe sets the settling time upper limit of the averaging filter in the
auto-averaging mode for the Continuous Average, Burst Average and Timeslot modes and limits the
length of the filter.
The query yields the current settling time upper limit of the averaging filter in the auto-averaging mode
for the Continuous Average, Burst Average and Timeslot modes.
Default setting: 30.0 [s]
SENSe:AVERage:COUNt:AUTO:NSRatio[?] 0.0001 to 1.0
SENSe:AVERage:COUNt:AUTO:NSRatio determines the relative noise component in the measurement
result for the Continuous Average, Burst Average and Timeslot modes if auto-averaging is operated in
the corresponding mode (SENSe:AVERage:COUNt:AUTO:TYPE NSRatio). The noise component is
defined as the magnitude of the level variation in dB caused by the inherent noise of the sensor (two
standard deviations).
The query yields the relative noise component in the result for the Continuous Average, Burst Average
or Timeslot modes.
Default setting: 0.01 [dB]
SENSe:AVERage:COUNt:AUTO:RESolution[?] 1 to 4
SENSe:AVERage:COUNt:AUTO:RESolution sets the resolution index for the automatic averaging filter
in the Continuous Average, Burst Average and Timeslot modes if it is operated in the RESolution mode.
The resolution index equals the number of decimal places that have to be taken into account for the
further processing of the measurement result in dBm, dBµV or dB. The normal mode is designed in a
similar manner as for the predecessors R&S NRVS and R&S NRVD or other commercial power meters.
The higher the selected index, the better the measurement result is filtered without the last significant
place (0.01 dB with an index of 3) actually being set. The NSRatio setting is recommended instead.
The query yields the resolution index for the Continuous Average, Burst Average and Timeslot modes.
Default setting: 3
SENSe:AVERage:COUNt:AUTO:SLOT[?] 1 to <SENSe:POWer:TSLot:AVG:COUNt>
SENSe:AVERage:COUNt:AUTO:SLOT defines the timeslot, whose power is referenced by
auto-averaging in the Timeslot mode. The timeslot is addressed via its number, the counting beginning
with 1. The timeslot number must not exceed the number of the currently set timeslots. If a valid
timeslot number is initially set and then the number of timeslots reduced to a value that is smaller than
the initial timeslot number, the initial value is automatically set to the new timeslot number, i.e.
auto-averaging references the most recent timeslot.
The query yields the number of the current timeslot, whose power is referenced by auto-averaging in
the Timeslot mode.
Default setting: 1
R&S NRP-Z11/-Z21 Remote Control - Commands
1137.7406.12 6.9 E-2
SENSe:AVERage:COUNt:AUTO:TYPE[?] RESolution | NSRatio
SENSe:AVERage:COUNt:AUTO:TYPE defines the automatic averaging filter mode in the Continuous
Average, Burst Average and Timeslot modes. The RESolution parameter sets the mode usual for
power meters; NSRatio predefines the compliance to an exactly defined noise component.
The query yields
• 1 for RESolution,
• 2 for NSRatio.
Default setting: RESolution
SENSe:AVERage:RESet
SENSe:AVERage:RESet initializes the averaging filter for the Continuous Average, Burst Average or
Timeslot modes. This is useful if a high averaging factor is set in the SENSe:AVERage
:TCONtrol MOVing filter mode and if the power to be measured has significantly decreased since the
previous measurement, e.g. by several powers of ten. In this case, previous measurement results still
contained in the averaging filter strongly affect the settling of the display; as a result, the advantage of
the SENSe:AVERage:TCONtrol MOVing filter mode, i.e. the ability to detect trends in the measurement
result while the measurement is still in progress, is lost. The SENSe:AVERage:RESet command solves
this problem by deleting all previous measurement results that the averaging filter contains. After
initialization, the filter length gradually increases from 1 to its nominal value SENSe:AVERage:COUNt,
so that trends in the measurement result become quickly apparent. However, this procedure does not
shorten the measurement time required in order for the averaging filter to settle completely.
SENSe:AVERage:STATe[?] OFF | ON
SENSe:AVERage:STATe switches on or off the averaging filter for the Continuous Average, Burst
Average and Timeslot modes.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: ON
SENSe:AVERage:TCONtrol[?] MOVing | REPeat
SENSe:AVERage:TCONtrol (terminal control) defines the behaviour of the averaging filter in the
Continuous Average, Burst Average and Timeslot modes. As soon as a new measured value is shifted
to the FIR filter, a new average value is available at the filter output, which is obtained from the new
measured value and the other values stored in the filter.
The MOVing parameter defines that each new average value is output as a measurement result. This
allows tendencies in the result to be recognized during the measurement procedure.
The REPeat parameter defines that a new result is output after the FIR filter has been filled with new
measured values. This ensures that no redundant information is output.
The query yields
• 1 for MOVing,
• 2 for REPeat.
Default setting: MOVing
Remote Control - Commands R&S NRP-Z11/-Z21
1137.7406.12 6.10 E-2
SENSe:CORRection:DCYCle[?] 0.001 to 99.999
SENSe:CORRection:DCYCle sets the duty cycle to a percent value for the correction of pulse-
modulated signals. With the correction activated, the sensor calculates the signal pulse power from this
value and the mean power. Since the duty cycle is only useful in the Continuous Average mode and the
normal mode, it is evaluated only there.
The query yields the current duty cycle in percent.
Default setting: 1.0 [%]
SENSe:CORRection:DCYCle:STATe[?] OFF | ON
SENSe:CORRection:DCYCle:STATe ON activates the duty cycle correction and thus the pulse-power
measurement whereas SENSe:CORRection:DCYCle:STATe OFF deactivates it.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: OFF
SENSe:CORRection:OFFSet[?] –200.0 to 200.0
SENSe:CORRection:OFFSet defines a fixed offset in dB, which is used to correct the measured value.
(When a log scale is used, the offset is added to the measured value; this is the reason why the
command has this name.)
The attenuation of an attenuator located ahead of the sensor or the coupling attenuation of a directional
coupler is taken into account with a positive offset, i.e. the sensor calculates the power at the input of
the attenuator or directional coupler. A negative offset can be used to correct the influence of a gain
connected ahead.
The query yields the set offset in dB.
Default setting: 0.0 [dB]
SENSe:CORRection:OFFSet:STATe[?] OFF | ON
SENSe:CORRection:OFFSet:STATe ON activates the offset correction and
SENSe:CORRection:OFFSet:STATe OFF deactivates it.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: OFF
R&S NRP-Z11/-Z21 Remote Control - Commands
1137.7406.12 6.11 E-2
SENSe:CORRection:SPDev:STATe[?] OFF | ON
SENSe:CORRection:SPDevice:STATe ON activates the s-parameter data set for a component
(attenuator, directional coupler) connected ahead of the sensor. Parameter OFF deactivates it.
The use of s-parameters instead of a fixed offset
(see group of commands SENSe:CORRection:OFFSet)
allows more precise measurements, since the interactions between the sensor, the source and
components connected between them can be taken into account. (For detailed information on loading
s-parameter data sets, refer to section 3.) The sensor has no factory-set s-parameter data set. In this
state, the SENSe:CORRection:SPDevice:STATe ON command generates an error message.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting:
The factory-set default setting of the sensor is OFF. On loading an s-parameter table, the default setting
can be redefined (see section 3).
SENSe:FREQuency[?] 10.0e6 to 8.0e9 (NRP-Z11) or 18.0e9 (NRP-Z21)
SENSe:FREQuency transfers the carrier frequency of the RF signal to be measured; this frequency is
used for the frequency-response correction of the measurement result. The center frequency is set for
broadband signals (spread-spectrum signals, multicarrier signals).
The query yields the set carrier frequency in Hz.
Default setting: 50.0e6 [Hz]
Remote Control - Commands R&S NRP-Z11/-Z21
1137.7406.12 6.12 E-2
SENSe:FUNCtion[?] <sensor_function>
SENSe:FUNCtion <sensor_function> sets the sensor to one of the following measurement modes:
Table 6-3 Measurement modes
<sensor_function> Description of the measurement mode
"POWer:AVG" Continuous Average
After occurrence of the trigger event, the mean power is measured in a time interval (sampling
window) whose width is defined with SENSe:POWer:AVG:APERture.
The single measurements are performed in pairs to obtain a more accurate measurement result by
differentiation. With the averaging function activated, this operation is repeated the number of times
specified by the averaging factor. With the averaging function activated, the actual measurement time
is thus
2 × <SENSe:AVERage:COUNt> × <SENSe:POWer:AVG:APERture>
and with deactivated averaging function
2 × <SENSe:POWer:AVG:APERture>.
Trigger events start one or several measurements in the Continuous Average mode (depending on the
TRIGger:COUNt parameter).
"POWer:TSLot:AVG" Timeslot
The power is measured in a defined number of consecutive timeslots. Up to 128 timeslots have the
same width, which is defined by SENSe:POWer:TSLot :WIDTh. Their quantity is defined by
SENSe:POWer:TSLot:COUNt. The measurement result is an array, which contains as many elements
as timeslots. Each element represents the average power in one of the timeslots. After each
occurrence of the trigger event, a measurement is performed in all timeslots. The single
measurements are also performed in pairs in this mode to obtain a more accurate measurement result
by differentiation. With the averaging function activated, this operation is repeated the number of times
specified by the averaging factor. With the averaging function activated, the actual measurement time
is thus
2 × <SENSe:AVERage:COUNt> × <SENSe:POWer:TSLot:AVG:WIDTh>
and with deactivated averaging function
2 × <SENSe:POWer:TSLot:AVG:WIDTh>.
Note that a corresponding number of trigger events must be available.
"POWer:BURSt:AVG" Burst Average
This mode is used for the measurement of the average power of repetitive single bursts, for example.
The time interval (integration time) in which the average power is measured is not predefined. Instead,
a special algorithm detects the beginning and end of the burst and ensures the synchronization of the
sampling window. However, the user must define the dropout tolerance, a time criterion for detecting
the pulse or burst end, using SENSe:POWer:BURSt:DTOLerance.
In the Burst Average mode, external trigger events (irrespective of the setting of the TRIGger:SOURce
parameter) and the TRIGger:DELay parameter are ignored.
"XTIMe:POWer" Scope
The Scope mode is similar to the Timeslot mode. Since, however, up to 1024 consecutive timeslots
(called "points" here) are possible, the maximum averaging factor is limited to 8192 due to the storage
capacity. In the Scope mode, other limits than in the Timeslot mode apply to the timeslot width.
SENSe:TRACe:REALtime ON optimizes the time resolution. The differentiation and averaging filter are
ignored.
R&S NRP-Z11/-Z21 Remote Control - Commands
1137.7406.12 6.13 E-2
Time intervals that are excluded from the measurement can be set at the beginning and the end of the
sampling window or timeslot in the measurement modes Burst Average and Timeslot.
(SENSe:TIMing:EXCLude:STARt and -:STOP).
The query yields
• 1 for "POWer:AVG",
• 2 for "POWer:TSLot:AVG",
• 4 for "POWer:BURSt:AVG",
• 8 for "XTIMe:POWer".
Default setting: "POWer:AVG"
SENSe:POWer:AVG:APERture[?] 0.0001 to 0.3
SENSe:POWer:AVG:APERture defines the time interval (sampling window) for the Continuous Average
mode; measured values are continuously recorded in this interval. In manual operation, the default
setting of 20 ms in conjunction with the activated smoothing (see
SENSe:POWer:AVG:SMOothing:STATe) is sufficient in most cases. Another value, which is normally
higher, is required when the measurement result shows variations due to modulation. Especially with
low-frequency modulation, it is useful to adapt the size of the sampling window exactly to the
modulation period, which yields an optimum stable display.
Table 6-4 Optimum selection of the sampling window size (N = 1, 2, 3, …)
Smoothing Optimum sampling window size
OFF N × modulation period / 2
ON N × modulation period × 2
The theoretically shortest measurement time can then be obtained only with smoothing deactivated. As
the number of modulation periods that fit into a sampling window increases, the issue of whether N is
an integer becomes more critical. With smoothing activated, approx. 5 periods are sufficient to reduce
variations due to modulation to an acceptable extent; variations are no longer perceptible with more
than 9 periods. With smoothing deactivated, the situation is significantly unfavourable. In this case, 5
instead of 300 periods are required and the variations completely disappear as of 3000 periods.
The query yields the currently set width of the sampling window in seconds.
Default setting: 0.02 [s]
SENSe:POWer:AVG:BUFFer:SIZE[?] 1 to 1024
SENSe:POWer:AVG:BUFFer:SIZE sets the buffer size for the buffered Continuous Average mode.
The query yields the current buffer size for the buffered Continuous Average mode.
Default setting: 1

SENSe:POWer:AVG:BUFFer:STATe[?] OFF | ON
The buffered Continuous Average mode is activated with ON and deactivated with OFF. In this mode,
the results generated by trigger events are collected in the sensor until the buffer is filled. All results are
then transferred as block data. The measurement rate obtained is thus higher than in the non-buffered
Continuous Average mode. The maximum measurement rate is obtained by combining the buffered
mode with multiple triggering (see parameter TRIGger:COUNt). The size of the result buffer is set with
the SENSe:POWer:AVG:BUFFer:SIZe command.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: OFF
SENSe:POWer:AVG:SMOothing:STATe[?] OFF | ON
The ON parameter activates a smoothing filter for modulated signals in the Continuous Average mode
and OFF deactivates it. The smoothing filter is a steep-edge digital lowpass filter used to suppress
variations of results caused by low-frequency modulation. This parameter should be activated to reduce
variations in results due to modulation when the size of the sampling window cannot or should not be
exactly adapted to the modulation period. If the selected sampling window is 5 to 9 times larger than a
modulation period, the variations in display are normally sufficiently reduced. With smoothing
deactivated, 300 to 3000 periods are required to obtain the same effect.
With smoothing deactivated, the sampling values are considered equivalent and averaged in a
sampling window, which yields an integrating behaviour of the measuring instrument. As described
above, optimum suppression of variations in the result is thus obtained when the size of the sampling
window is exactly adapted to the modulation period. Otherwise, the modulation can have a
considerable influence, even if the sampling window is much larger than the modulation period. The
behaviour can be considerably improved by subjecting sampling values to weighting (raised-von-Hann
window), which corresponds to video filtering. This is exactly what happens with activated smoothing.
Since the smoothing filter increases the inherent noise of the sensor by approx. 20%, it should remain
deactivated if it is not required.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: ON
SENSe:POWer:BURSt:DTOLerance[?] 0.0 to 0.003
SENSe:POWer:BURSt:DTOLerance defines the dropout tolerance, a parameter for reliably detecting
the burst end in the Burst Average mode with modulated signals (e. g. with digital standards NADC,
PDC, PHS, etc.). The dropout tolerance should be selected larger than the longest amplitude drop and
smaller than the gap between two consecutive bursts. The default value is sufficient for all usual digital
communication standards.
The query yields the dropout tolerance for the Burst Average mode.
Default setting: 0.0001 [s]

SENSe:POWer:TSLot:AVG:COUNt[?] 1 to 128
For the Timeslot mode, SENSe:POWer:TSLot:AVG:COUNt sets the number of consecutive timeslots
that are to be processed after each trigger event.
The query yields the number of consecutive timeslots.
Default setting: 1
SENSe:POWer:TSLot:AVG:WIDTh[?] 0.0001 to 0.1
SENSe:POWer:TSLot:AVG:WIDTh sets the length of a timeslot in seconds for the Timeslot mode.
The query yields the length of a timeslot in seconds for the Timeslot mode.
Default setting: 0.001 [s]
SENSe:RANGe[?] 0 to 2
SENSe:RANGe selects the measurement path of the sensor. The sensor has three separate
measurement paths. Path 1 is the most sensitive, path 2 medium and path 3 the least sensitive.
SENSe:RANGe 0 selects path 1, SENSe:RANGe 1 path 2 and SENSe:RANGe 2 path 3.
The dynamic ranges of these measurement paths depend on temperature and are model-specific.
Reference values are 40 µW(–14 dBm) for the most sensitive measurement path, 4 mW (6 dBm) for the
medium one and 400 mW (26 dBm) for the least sensitive.
The query yields
• 0 for path 1,
• 1 for path 2,
• 2 for path 3.
If the measurement path is selected manually (SENSe:RANGe:AUTO OFF), the currently selected
measurement path is output. With automatic selection, the last path that was set manually is output. It is
therefore immediately reset after deactivating the automatic function.
Default setting: 2 (least sensitive path)

1137.7406.12 6.16 E-2
SENSe:RANGe:AUTO[?] OFF | ON
SENSe:RANGe:AUTO ON activates the automatic selection of the measurement path and
SENSe:RANGe:AUTO OFF deactivates it.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: ON
SENSe:RANGe:AUTO:CLEVel[?] –20.0 to 0.0
SENSe:RANGe:AUTO:CLEVel is used to reduce the transition range between measurement paths 1
and 2 or 2 and 3 by the indicated value (in dB). This can improve the measurement accuracy for
signals with a high peak-to-average ratio, since the headroom for modulation peaks becomes larger.
The disadvantage is that the S/N ratio is reduced at the lower limits of the transition ranges.
The query yields the offset of transition ranges between measurement channels 1 and 2 or 2 and 3.
Default setting: 0.0 [dB]
SENSe:SAMPling[?] FREQ1 | FREQ2
SENSe:SAMPling is used to vary the sampling frequency of the analog-digital converter in the sensor.
With parameter specification FREQ1 the sampling frequency is 133.400 kHz, and 119.467 kHz with
parameter FREQ2. This is provided to suppress interfering low-frequency mixture products from signal
components and the sampling frequency.
The query yields
• 1 for FREQ1,
• 2 for FREQ2.
Default setting: FREQ1
SENSe:SGAMma:CORRection:STATe[?] OFF | ON
SENSe:SGAMma:CORRection:STATe ON initiates the use of the complex reflection coefficient of the
source defined with SENSe:SGAMma:MAGNitude and SENSe:SGAMma:PHASe for the correction of
interactions between the sensor, the source and the components connected between them (see
SENSe:CORRection:SPDevice:STATe). This compensates for the source mismatch, which often
largely contributes to measurement uncertainty.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: OFF

1137.7406.12 6.17 E-2
SENSe:SGAMma:MAGNitude[?] 0.0 to 1.0
SENSe:SGAMma:MAGNitude defines the magnitude of the complex reflection coefficient of the source.
A value of 0.0 corresponds to an ideal matched source and a value of 1.0 to total reflection.
The query yields the set magnitude.
Default setting: 0.0
SENSe:SGAMma:PHASe[?] –360.0 to 360.0
SENSe:SGAMma:MAGNitude defines the phase angle (in degrees) of the complex reflection coefficient
of the source.
The query yields the set phase angle.
Default setting: 0.0 [°]
SENSe:TRACe:AVERage:COUNt[?] 1 to 65536
SENSe:TRACe:AVERage:COUNt is used to set the number of measured values to be averaged in the
Scope mode for the formation of the measurement result. The higher this averaging factor, the lesser
the fluctuation the measured values and the longer the measurement time. The parameter is rounded
off to the next power-of-two number.
The query yields the averaging factor used in the Scope mode.
The averaging function must be activated with SENSe:TRACe:AVERage:STATe ON so
that the set averaging factor becomes effective.
Default setting: 4
SENSe:TRACe:AVERage:COUNt:AUTO[?] OFF | ON | ONCE
SENSe:SWep:AVERage:COUNt:AUTO activates (auto-averaging) or deactivates (fixed-filter mode) the
automatic determination of the averaging factor in the Scope mode. If auto-averaging is activated, the
averaging factor is continuously determined and set depending on the level of power and other
parameters.
SENSe:TRACe:AVERage:COUNt:AUTO ON activates auto-averaging and SENSe:TRACe
:AVERage:COUNt:AUTO OFF deactivates it. When deactivation occurs, the previous, automatically
determined averaging factor is used in the fixed-filter mode. The SENSe:TRACe:AVERage
:COUNt:AUTO ONCE command ensures that a new averaging factor is determined by the filter
automatic function under the current measurement conditions and that this factor is used in the fixed-
filter mode.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: OFF
Remote Control - Commands R&S NRP-Z11/-Z21
1137.7406.12 6.18 E-2
SENSe:TRACe:AVERage:COUNt:AUTO:MTIMe[?] 1.0 to 999.99
SENSe:TRACe:AVERage:COUNt:AUTO:MTIMe sets the settling time upper limit of the averaging filter
in the auto-averaging mode for the Scope mode and limits the length of the filter.
The query yields the current settling time upper limit of the averaging filter in the auto-averaging mode
for the Scope mode.
Default setting: 30.0 [s]
SENSe:TRACe:AVERage:COUNt:AUTO:NSRatio[?] 0.0001 to 1.0
SENSe:TRACe:AVERage:COUNt:AUTO:NSRatio determines the relative noise component in the
measurement result for the Scope mode if auto-averaging is operated in the corresponding mode
(SENSe:TRACe:AVERage:COUNt:AUTO:TYPE NSRatio). The noise component is defined as the
magnitude of the level variation in dB caused by the inherent noise of the sensor (two standard
deviations).
The query yields the relative noise component in the measurement result in the Scope mode.
Default setting: 0.01 [dB]
SENSe:TRACe:AVERage:COUNt:AUTO:RESolution[?] 1 to 4
SENSe:TRACe:AVERage:COUNt:AUTO:RESolution sets the resolution index for the automatic
averaging filter in the Scope mode when it is operated in the RESolution mode. The resolution index is
equal to the number of decimal places that have to be taken into account for the further processing of
the measurement result in dBm, dBµV or dB. Thus, the design of the normal mode is similar to that for
the predecessors R&S NRVS and R&S NRVD or other commercial power meters. The higher the
selected index, the better the measurement result is filtered without the last significant place (0.01 dB
with an index of 3) being actually set. The NSRatio setting is recommended instead.
The query yields the resolution index for the Scope mode.
Default setting: 3
SENSe:TRACe:AVERage:COUNt:AUTO:POINt[?] 1 to <SENSe:TRACe:POINts>
SENSe:TRACe:AVERage:COUNt:AUTO:SLOT defines the "point" whose power is referenced by
auto-averaging in the Scope mode. The "point" is addressed via its number, the counting beginning
with 1. The "point" number must not exceed the number of the currently set "points". If a valid "point"
number is initially set and then the number of "points" reduced to a value that is smaller than the initial
"point" number, the initial value is automatically set to the new "point" number, i.e. auto-averaging
references the most recent "point".
The query yields the number of the current "point" whose power is referenced by auto-averaging in the
Scope mode.
Default setting: 1

SENSe:TRACe:AVERage:COUNt:AUTO:TYPE[?] RESolution | NSRatio
SENSe:TRACe:AVERage:COUNt:AUTO:TYPE defines the mode of the automatic averaging filter in the
Scope mode. The RESolution parameter sets the mode usual for power meters; NSRatio predefines the
compliance to an exactly defined noise component.
The query yields
• 1 for RESolution,
• 2 for NSRatio.
Default setting: RESolution
SENSe:TRACe:AVERage:STATe[?] OFF | ON
SENSe:TRACe:AVERage:STATe switches the averaging filter on or off for the Scope mode.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: ON
SENSe:TRACe:AVERage:TCONtrol[?] MOVing | REPeat
SENSe:TRACe:AVERage:TCONtrol (terminal control) defines the behaviour of the averaging filter in
the Scope mode. As soon as a new measured value is shifted to the FIR filter, a new mean is available
at the filter output, which is obtained from the new measured value and the other values stored in the
filter.
The MOVing parameter defines that each new average value is output as a measurement result. This
allows trends in the result to be recognized during the measurement procedure.
The REPeat parameter defines that a new result is output after the FIR filter has been filled with new
measured values. This ensures that no redundant information is output.
The query yields
• 1 for MOVing,
• 2 for REPeat.
Default setting: MOVing
SENSe:TRACe:MPWidth?
SENSe:TRACe:MPWidth? provides the minimum point width for the Scope mode, i.e. time resolution in
seconds is determined as a function of the TRIGger:SOURce parameter while taking into consideration
how the sensor operates. The display may be incorrect if
<SENSe:TRACe:POINts> × <SENSe:TRACe:MPWidth> < SENSe:TRACE:TIME>
One way to prevent this is to decrease the number of points of the Scope measurement sequence.

SENSe:TRACe:OFFSet:TIME[?] – (<TRIGger:DELay> + 0.005) to 100.0
This command is used to shift the timeslot for measured-data acquisition along the time axis in the
Scope mode without modifying the value of TRIGger:DELay. Positive values yield an additional delay
and negative values a correspondingly earlier measured-data acquisition.
The query yields the set time in seconds.
Default setting: 0.0 [s]
SENSe:TRACe:POINts[?] 1 to 1024
This command defines the time resolution of the measurement result. Each "point" represents a time
interval whose duration is obtained from the length of the timeslot (command SENSe:TRACe:TIME)
divided by the number of "points". The measurement result for a "point" equals the average power over
the associated time interval.
The query yields the number of set "points".
Default setting: 100
SENSe:TRACe:REALtime[?] OFF | ON
SENSe:TRACe:REALtime ON suppresses the measured-value acquisition in pairs so that single
operations can be recorded in this setting. Since the averaging filter of the sensor is not used,
SENSe:AVERage:STATe is ignored, but is not affected.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: OFF
SENSe:TRACe:TIME[?] 0.0001 to 0.3
SENSe:TRACe:TIME sets the duration of the timeslot in the Scope mode. This timeslot is divided into a
number of equal intervals, in which the average power is determined. The number of intervals equals
the number of test points, which is set with the command SENSe:TRACe:POINts.
The query yields the duration of the timeslot in the Scope mode (in s).
Default setting: 0.01 [s]
SENSe:TIMing:EXCLude:STARt[?] 0.0 to 0.1
SENSe:TIMing:EXClude:STARt defines the exclusion time at the beginning of the measurement

ABORt
ABORt interrupts the current measurement and sets the sensor to the IDLE state (normal case).
However, if the sensor is in the continuous measurement mode (setting INITiate:CONTinuous ON), the
IDLE state is immediately exited and the sensor enters the WAIT_FOR_TRIGGER state.
INITiate:CONTinuous[?] OFF | ON
INITiate:CONTinuous ON activates the continuous measurement mode. In this mode, a new
measurement is automatically started when a measurement is terminated. The sensor first enters the
WAIT_FOR_TRIGGER state and begins with the measurement as soon as the trigger condition is
fulfilled. Once the measurement is completed, the sensor again enters the WAIT_FOR_TRIGGER
state. The sensor will measure continuously assuming continuous trigger events.
In contrast, each measurement cycle must be explicitly started with the INITiate:IMMediate command
after the INITiate:CONTinuous OFF command has been sent. After triggering and completion of the
measurement, the sensor enters the IDLE status and remains in this status until a new measurement is
started with the INITiate:IMMediate command.
R&S NRP-Z11/-Z21 Remote Control - Commands
1137.7406.12 6.27 E-2
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: OFF
INITiate:IMMediate
INITiate:IMMediate starts a single measurement cycle. The sensor first changes from the IDLE state to
the WAIT_FOR_TRIGGER state and begins with the measurement as soon as the trigger condition is
fulfilled. Once the measurement is completed, the sensor again enters the IDLE state. Since the
command is ignored during measurement, it normally has no effect in the continuous mode (setting
INITiate:CONTinuous ON).
TRIGger:ATRigger:STATe[?] OFF | ON
TRIGger:ATRigger:STATe ON causes an artificial trigger event to be triggered if no trigger is recorded
more than 10 s after the measurement has been started (only in the Scope mode).
TRIGger:ATRigger:STATe OFF deactivates the trigger automatic function.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: OFF
TRIGger:COUNt[?] 1 to 2 × 109
This setting is designed for applications in which several consecutive measurements have to be
performed by sending the INITiate:IMMediate command only once, e.g. to obtain a higher measurement
speed. The gap between a single measurement and the continuous measurement mode is thus closed.
The number of measurements is defined with the parameter associated with the TRIGger:COUNt
command. This number equals the number of results yielded by the sensor at the end of the
measurement.
The TRIGger:COUNt command does not define the number of trigger events required for
performing the entire measurement task. The number may vary depending on the
measurement mode.
A further increase in the measurement speed can be obtained by combining the mode
used with the buffered mode. The results are not made available immediately but as a
block at the end of the measurement sequence (see group commands
SENSe:POWer:AVG:BUFFer).
The query yields the number of measurements performed with the INIT:IMMediate command after a
measurement start.
Default setting: 1
Remote Control - Commands R&S NRP-Z11/-Z21
1137.7406.12 6.28 E-2
TRIGger:DELay[?] x to 100.0
TRIGger:DELay defines the delay (in seconds) between the occurrence of the trigger event and the
beginning of the measurement itself for the Timeslot and Scope modes. This parameter is ignored in
the Burst Average mode. Pretriggering is obtained by means of negative values; with bus-triggered
measurements (see TRIGger:SOURce), the parameter must be set to positive values or zero to avoid
measurement errors.
The query yields the set trigger delay for the Timeslot and Scope modes (in seconds).
Lower limit x of the parameter
Modes Continuous Average, Burst Average and Timeslot: x = –0.005
Mode Scope: x = – (<SENSe:TRACe:OFFSet:TIME> + 0.005)
Default setting: 0.0 [s]
TRIGger:DELay:AUTO[?] OFF | ON
TRIGger:DELay:AUTO ON ensures by means of an automatically determined delay that a
measurement is only started after the sensor has settled. This is important when thermal sensors are
used. The automatically determined delay is ignored if a longer period was set with TRIGger:DELay.
This does not overwrite the value of TRIGger:DELay. TRIGger:DELay:AUTO OFF deactivates this
function.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: ON
TRIGger:HOLDoff[?] 0.0 to 10.0
TRIGger:HOLDoff suppresses trigger events within the set holdoff time (in s), starting from the time of
the last successful triggering.
The query yields the set holdoff time (in s).
Default setting: 0.0 [s]
TRIGger:HYSTeresis[?] 0.0 to 10.0
TRIGger:HYSTeresis sets the hysteresis of the internal trigger threshold (parameter TRIGger:LEVel).
Hysteresis is the magnitude (in dB) by which the trigger signal level falls below the trigger threshold
(with positive trigger edge) to enable triggering again. The case is exactly the opposite with a negative
trigger edge. The trigger hysteresis setting is only relevant to the INTernal trigger source.
The query yields the trigger hysteresis in dB.
Default setting: 0.0 [dB]
TRIGger:IMMediate
TRIGger:IMMediate triggers a generic trigger event that causes the sensor to exit immediately the
WAIT_FOR_TRIGGER state irrespective of the trigger source and the trigger delay and begin with the
measurement. The command is the only means of starting a measurement when the trigger source is
set to HOLD.

TRIGger:SLOPe[?] POSitive | NEGative
TRIGger:SLOPe defines the edge of the trigger event with internal and external triggering in the
Timeslot and Scope modes. In this connection, positive means increasing envelope power (with internal
triggering) or increasing voltage (with external triggering). As in the Burst Average mode, this command
has no effect in conjunction with trigger sources BUS, HOLD and IMMediate.
The query yields
• 1 for POSitive,
• 2 for NEGative.
Default setting: POSitive
TRIGger:SOURce[?] BUS | EXTernal | HOLD | IMMediate | INTernal
TRIGger:SOURce sets the trigger source.
• BUS: Triggering with command *TRG or TRIGger:IMMediate.
• EXTernal: Triggering via USB Adapter R&S NRP-Z3. Relevant trigger parameters:
TRIGger:DELay and TRIGger:SLOPe.
• HOLD: Triggering only with command TRIGger:IMMediate.
• IMMediate: Automatic triggering without explicit event.
• INTernal: Triggering by the measurement signal. Relevant trigger parameters:
TRIGger:LEVel, TRIGger:DELay and TRIGger:SLOPe (not in the Burst Average mode).
The query yields
• 1 for BUS,
• 2 for EXTernal,
• 4 for HOLD,
• 8 for IMMediate,
• 16 for INTernal.
Default setting: IMMediate

1 Performance Test
Preliminary Remarks
Verifying the data sheet specifications for the Power Sensors R&S NRP-Z11 and R&S NRP-Z21
requires a considerable amount of equipment and care. Rohde & Schwarz therefore recommends using
the Power Calibration System R&S NRVC or corresponding equipment that yields the same accuracy.
The tests are to be carried out directly at the manufacturer, its representatives or subsidiaries or at
calibration sites that are equipped accordingly.
A quick test (see page 1.5) is recommended for checking the sensor with simple means.
Test Instructions
• The tests are to be performed at an ambient temperature of 20°C to 25°C. The DUT should be
connected to the (activated) R&S NRP base unit for at least 30 minutes before the tests are
performed.
• The test limits used in the following sections are based on the data sheet for the sensors
R&S NRP-Z11 and R&S NRP-Z21. The test limits are valid only on the conditions defined in the
corresponding test step. They are therefore not legally binding as accuracy specifications; only data
sheet specifications are legally binding.

For detailed information about the performance test, refer to the operating manual for Calibration Kit
R&S NRVC.
SWR measurement has to be carried out on a separate network analyzer. Evaluation is performed by
Calibration Software Recal.
Performance Test with Other Measuring Equipment
Checking Absolute Measuring Accuracy
The sensor contains three measurement paths. Individual calibration factors are stored for these
measurement paths in the sensor. The measurement paths therefore have to be checked separately.
(Table 1-1 and Table 1-2). The maximum permissible error depends on the calibration uncertainties of
the sensor (Table 1-2) and the uncertainties of the calibration system. It is recommended to combine
both uncertainties according to the RSS method (square root based on the sum of squares) and to use
the expanded combined uncertainty as the test limit.
To calibrate measurement path 1, the measurement result of measurement path 2 can be used if the
calibration system does not provide a calibration power of 10 µW or if its uncertainty is too high. In this
case, only the displayed difference between the two measurement paths will be checked (Table 1-3).

• Set measurement path in Sensor – Range menu on the R&S NRP.
• Set calibration frequency in Frequency menu on the R&S NRP.
• Read power on the R&S NRP and compare with power value of calibration system. At least three
measurements are recommended, with the sensor set to a different position with respect to the
output connector of the calibration system each time.
Checking the Linearity
The linearity check is performed at 50 MHz with autoranging activated. The reference power is 1 mW
(0 dBm). The maximum permissible linearity error depends on the linearity uncertainty of the sensor
(Table 1-4) and the linearity uncertainty of the calibration system. It is recommended to combine both
uncertainties according to the RSS method (square root based on the sum of squares) and to use the
expanded combined uncertainty as the test limit.

Procedure:
• Perform zeroing (without power applied).
• Set autoranging in Sensor – Range menu on the R&S NRP.
• Set 50 MHz in Frequency menu on the R&S NRP.
• Apply level of 0 dBm and activate Relative On in the Measurement menu on the R&S NRP. Use
the current measurement value as the reference value (Reset). Set unit to dB.
• Set the calibration level and compare the relative level measured by the R&S NRP with that of the
calibration system.

1137.7406.82 1.5 E-1
Quick Test
The following tests are used to check the R&S NRP-Z11 and R&S NRP-Z21 with simple means. If the
tests are passed, compliance of the sensors with the specifications within the complete frequency and
power range is largely ensured.
The test consists of:
• Zeroing.
• Absolute measuring accuracy at 0 dBm (50 MHz).
• Linearity when changing the measurement path (50 MHz).
• Input resistance (for DC voltage/current).
Test Instructions
• The tests are to be performed at an ambient temperature of 15°C to 35°C. The DUT should be
connected to the (activated) R&S NRP base unit for at least 30 minutes before the tests are
performed.
• The test limits used in the following sections are based on the data sheet but are valid only on the
conditions defined for the corresponding test step. They are therefore not binding as far as accuracy
is concerned but are strictly data sheet information.
• The entries made on the Power Meter R&S NRP are abbreviated as follows:
[<KEY>] Press front-panel key, e.g. [FREQ].
[<SOFTKEY>] Press softkey, e.g. [Range].
[<nn unit>] Enter value and confirm with unit, e.g. [3 GHz].
Successive entries are separated by [:], e.g. [ FREQ : 3 GHz ].

2 Adjustment
Preliminary Remarks
The Sensors R&S NRP-Z11 and R&S NRP-Z21 cannot be adjusted manually but have to be adjusted
by updating the calibration data in the memory. Calibration Software Recal, which is part of the
equipment supplied with the Calibration Kit R&S NRVC, is therefore required. The measurement results
for the absolute calibration of the three measurement paths which can be obtained during a
performance test (see Section 1) form the basis of the adjustment. The Calibration Kit R&S NRVC is
recommended but is not mandatory.
To ensure that the measuring accuracy corresponds to the data sheet values after the adjustment, the
calibration system must not have any inaccuracies that are higher than those given in the table below.

Description of Block Diagram
The Sensors R&S NRP-Z11 and R&S NRP-Z21 can determine the average power of almost any
modulated RF signal over a large dynamic range. They include all modules required for analog and
digital signal processing and provide fully corrected measured values. Communication with the
R&S NRP base unit is handled via a USB interface.
Three detectors are used to obtain the large dynamic range of 90 dB (–67 dBm to +23 dBm); the input
signal is fed unattenuated to path 1, attenuated by 20 dB to path 2 and attenuated by 40 dB to path 3.
Sensitivity is highest on path 1, medium on path 2 and lowest on path 3.
Depending on the RF input signal level, one or two test paths are driven at such a level that these paths
can be evaluated. A channel is always either driven at a very low level or overdriven. The output
voltages of the three detectors are amplified and digitized independently of each other to obtain a
continuous transition between the test paths. The digital values provided by the A/D converters undergo
various corrections (zero offset, temperature, linearity). A weighting algorithm then decides which path
or – in transition ranges – which two paths are to be evaluated, and forms a weighted measured value.
Integration values that represent the average power of the RF signal in a predefined integration period
are derived by averaging all sampling values within the integration period.
The final measured values are the averaged result from several integration values.
Microwave Detector
The microwave detector A3 is a hybrid circuit. It contains the three test paths and a thermistor for
temperature measurement. The detector has an RF signal input and a flexstrip connector for output
signals, control signals and operating voltages with the following assignment:
Table 3-1 Assignment of flexstrip connector W3
Connector Signal name Description

The casing of the detector is at ground potential.
R&S NRP-Z11/-Z21 Design and Circuit Description
1137.7406.82 3.3 E-1
Analog Board
The analog board A2 contains three test channels of the same design, each consisting of an
instrumentation amplifier, a buffer amplifier and a 14-bit A/D converter. The instrumentation amplifiers
amplify the output difference voltage of the detectors and convert it into a ground-referenced voltage.
The buffer amplifiers are quickly settling operational amplifiers with negative current feedback; they
isolate the instrumentation amplifiers from the current peaks occurring at the A/D converter inputs. The
A/D converters operate on the successive approximation principle. They have serial outputs.
The serial output data streams of the A/D converters are subjected to serial-parallel conversion in a
CPLD and stored in three addressable registers. The digital board consecutively addresses and reads
out these registers.
The analog board also comprises an 8-bit D/A converter for generating a noise-line large-scale dither
signal that is controlled by the digital board with a sequence of pseudo-random digital values.
The analog board contains a four-channel 12-bit A/D converter for measuring the substrate temperature
of the detector as well as for monitoring the operating voltages ±5 V and +1.75 V. The 12-bit A/D
converter is supplied by the 3.3 V operating voltage of the digital board and is thus operational even if
the voltage supply of the analog board is defective. It is connected to the synchronous serial interface of
the digital board and utilizes the MICROWIRE™ protocol.
The +5 V operating voltage of the analog board is generated from +3.3 V by a charge pump doubler
with subsequent linear regulator. The 5 V operating voltage is generated by a switching regulator with a
very low output ripple voltage.
Digital Board
The digital board A1 mainly consists of a controller based on a microcontroller Intel StrongARM
SA1110, two SRAMs (together 1 Mbyte) as random access memory and two flash PROMs (together
2 Mbyte).
The interface to the R&S NRP base unit is formed by connector X1 on the digital board. Besides the
four lines for the USB interface, the sensor cable contains two signal lines for applying a differential
trigger signal.
The connection to the analog board is established by press-in connector X2.
The digital board contains two DC/DC converters that generate the voltages +3.3 V and +1.75 V (for the
microcontroller core) from the +5 V operating voltage.

R&S NRP-Z11/-Z21 Installation of New R&S NRP-Z11/-Z21 Software
1137.7406.82 4.1 E-1
4 Firmware Update/Installation of Options
Chapter 4 provides information on the software update and the installation of options. Descriptions
enclosed with the software update or options can be filed here.
Installation of New R&S NRP-Z11/-Z21 Software
Use the Firmware Update program module to load new firmware for the Power Sensors R&S NRP-Z11
and NRP-Z21. The module is part of the R&S NRP Toolkit that is supplied on a CD-ROM together with
the power sensors and enables you to update the boot loader and the application firmware.
The current firmware versions can be downloaded from the R&S homepage on the Internet, since the
CD-ROM accompanying the power sensors contains the firmware status at the time of delivery.
Hardware and software requirements
The system requirements for a firmware update are the same as for the operation of the power sensor
on a PC (an update via the power meter is not possible):
• PC with free USB port.
• USB Interface Adapter R&S NRP-Z3 or R&S NRP-Z4.
• Operating system Windows™ 98, Windows™ ME, Windows™ 2000, or Windows™ XP.
• The R&S NRP Toolkit software must already be installed on your PC.
• One of the following files must be selected (depending on the software component to be updated):
• <Type>_Sensor<Version Number>.nrp Application
• Bootloader_<Version Number>.nrp, Boot loader
The files are available in the \software\firmware\sensors directory of the CD-ROM.
Installation of New R&S NRP-Z11/-Z21 Software R&S NRP-Z11/-Z21
1137.7406.82 4.2 E-1
Preparation
½ Connect the R&S NRP power sensor to the PC using one of the two USB interface adapters.
½ If a second R&S NRP-Z power sensor or an R&S NRP is connected to the PC, unplug these devices
from the PC.
½ Shortly afterwards, the PC should have identified the new USB hardware and assigned the
appropriate driver from the R&S NRP Toolkit to the power sensor (brief message in a small
window).
If you forgot to install the R&S NRP Toolkit beforehand, Windows will try in vain to
find a USB driver for the power sensor. If this happens, the R&S NRP-Zxx is
highlighted by a yellow exclamation mark in the Windows device manager. In this
case, proceed as follows:
½ Abort the dialog for driver installation.
½ Install the R&S NRP Toolkit from the CD-ROM.
Then manually assign the USB driver from the toolkit to the power sensor.
½ Go to Control Panel – Add/Remove Hardware and start the hardware assistant to
search for new components.
½ Mark the R&S NRP-Zxx in the list of hardware components and complete the driver
installation.
½ Unplug the power sensor and reconnect it.
R&S NRP-Z11/-Z21 Installation of New R&S NRP-Z11/-Z21 Software
1137.7406.82 4.3 E-1
Updating the application firmware
The update can be started as follows:
½ Either double-click the icon of the update file named
<Type>_Messkopf_<Version Number>.nrp
½ Or start NRP Toolkit – Firmware Update from the
Windows Start menu.
The dialog box on the left is displayed next.
½ If the update was started via the Windows Start menu,
enter the file name of the application firmware in the
Firmware File box (or search for the name by using the
Browse button).
½ Click the Start button to start the file transfer, which is
performed automatically.
½ Observe the following:
• Do not disconnect the power sensor from the PC.
• Neither connect nor disconnect the power supply for the
R&S NRP-Z3 adapter.
• Exit the Firmware Update program only after it has been
completely executed.
½ During the update, the State Messages box informs you
of the progress. The update has been completed
successfully if the message ’Device <Type
Designation><Serial Number> is active’
appears.
½ You can then use the power sensor for measuring.
Potential problems
- Error in the compatibility and consistency checks.
In this case, the update is aborted and an error message
is output.
½ Unplug the power sensor, reconnect it and start the
update again.

Updating the boot loader
The boot loader update is similar to the update of the
application firmware (see above).
½ Instead of the application, however, you must load the
new boot loader named
Bootloader_<Version Number>.nrp
Strictly observe the warnings under "Updating the
application firmware", since the destruction of the boot
loader will generally require a repair of the power sensor.
Potential problems
- The power sensor cannot be accessed after the update
(error message).
½ Exit the Firmware Update program, unplug the power
sensor from the PC and reconnect it. The power sensor is
now ready for operation.
