Basic Safety Instructions
Electrical safety
If the information on electrical safety is not observed either at all to the extent necessary, electric shock,
fire and/or serious personal injury or death may occur.
1. Prior to switching on the product, always ensure 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.
2. In the case of products of safety class I with movable power cord and connector, operation is
permitted only on sockets with an earthing contact and protective earth connection.
3. 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.
4. If the product does not have a power switch for disconnection from the AC supply network, the plug of
the connecting cable is regarded as the disconnecting device. In such cases, always ensure that the
power plug is easily reachable and accessible at all times (corresponding to the length of connecting
cable, approx. 2 m). Functional or electronic switches are not suitable for providing disconnection from
the AC supply network. If products without power switches are integrated into racks or systems, a
disconnecting device must be provided at the system level.
5. Never use the product if the power cable is damaged. Check the power cable on a regular basis to
ensure that it is in proper operating condition. By taking appropriate safety measures and carefully
laying the power cable, you can ensure that the cable will not be damaged and that no one can be
hurt by, for example, tripping over the cable or suffering an electric shock.
6. The product may be operated only from TN/TT supply networks fused with max. 16 A (higher fuse
only after consulting with the Rohde & Schwarz group of companies).
7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the
socket. Otherwise, sparks that result in fire and/or injuries may occur.
8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric
shocks.
9. 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.
10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial
computers, comply with the IEC60950-1/EN60950-1 or IEC61010-1/EN 61010-1 standards that apply
in each case.
11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in
operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the
product.
12. 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 licensed electrician.
13. 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 anyone who has access to the product, as
well as the product itself, is adequately protected from injury or damage.
1171.0000.42-05.00
Page 3
Basic Safety Instructions
14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of
lightning) can reach the product. Otherwise, the person operating the product will be exposed to the
danger of an electric shock.
15. Any object that is not designed to be placed in the openings of the housing must not be used for this
purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries.
16. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and
operating positions", item 1. Therefore, the equipment must be protected against penetration by
liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product
itself may be damaged, which can also lead to personal injury.
17. Never use the product under conditions in which condensation has formed or can form in or on the
product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water
increases the risk of electric shock.
18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network
or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such
as alcohol, acetone or diluents for cellulose lacquers.
Operation
1. Operating the products requires special training and intense concentration. Make sure that persons
who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries
or material damage may occur. It is the responsibility of the employer/operator to select suitable
personnel for operating the products.
2. Before you move or transport the product, read and observe the section titled "Transport".
3. As with all industrially manufactured goods, the use of substances that induce an allergic reaction
(allergens) such as nickel cannot be generally excluded. If you develop an allergic reaction (such as a
skin rash, frequent sneezing, red eyes or respiratory difficulties) when using a Rohde & Schwarz
product, consult a physician immediately to determine the cause and to prevent health problems or
stress.
4. Before you start processing the product mechanically and/or thermally, or before you take it apart, be
sure to read and pay special attention to the section titled "Waste disposal", item 1.
5. Depending on the function, certain products such as RF radio equipment can produce an elevated
level of electromagnetic radiation. Considering that unborn babies require increased protection,
pregnant women must be protected by appropriate measures. Persons with pacemakers may also be
exposed to risks from electromagnetic radiation. The employer/operator must evaluate workplaces
where there is a special risk of exposure to radiation and, if necessary, take measures to avert the
potential danger.
6. Should a fire occur, the product may release hazardous substances (gases, fluids, etc.) that can
cause health problems. Therefore, suitable measures must be taken, e.g. protective masks and
protective clothing must be worn.
7. If a laser product (e.g. a CD/DVD drive) is integrated into a Rohde & Schwarz product, absolutely no
other settings or functions may be used as described in the product documentation. The objective is to
prevent personal injury (e.g. due to laser beams).

aspectos de seguridad (p. ej. el enchufe, los transformadores o los fusibles), solamente podrán ser
sustituidos por partes originales. Después de cada cambio de partes relevantes para la seguridad
deberá realizarse un control de seguridad (control a primera vista, control del conductor de
protección, medición de resistencia de aislamiento, medición de la corriente de fuga, control de
funcionamiento). Con esto queda garantizada la seguridad del producto.
Baterías y acumuladores o celdas
Si no se siguen (o se siguen de modo insuficiente) las indicaciones en cuanto a las baterías y
acumuladores o celdas, pueden producirse explosiones, incendios y/o lesiones graves con posible
consecuencia de muerte. El manejo de baterías y acumuladores con electrolitos alcalinos (p. ej. celdas de
litio) debe seguir el estándar EN 62133.
1. No deben desmontarse, abrirse ni triturarse las celdas.
2. Las celdas o baterías no deben someterse a calor ni fuego. Debe evitarse el almacenamiento a la luz
directa del sol. Las celdas y baterías deben mantenerse limpias y secas. Limpiar las conexiones
sucias con un paño seco y limpio.
3. Las celdas o baterías no deben cortocircuitarse. Es peligroso almacenar las celdas o baterías en
estuches o cajones en cuyo interior puedan cortocircuitarse por contacto recíproco o por contacto con
otros materiales conductores. No deben extraerse las celdas o baterías de sus embalajes originales
hasta el momento en que vayan a utilizarse.
4. Mantener baterías y celdas fuera del alcance de los niños. En caso de ingestión de una celda o
batería, avisar inmediatamente a un médico.
5. Las celdas o baterías no deben someterse a impactos mecánicos fuertes indebidos.

6. En caso de falta de estanqueidad de una celda, el líquido vertido no debe entrar en contacto con la
piel ni los ojos. Si se produce contacto, lavar con agua abundante la zona afectada y avisar a un
médico.
7. En caso de cambio o recarga inadecuados, las celdas o baterías que contienen electrolitos alcalinos
(p. ej. las celdas de litio) pueden explotar. Para garantizar la seguridad del producto, las celdas o
baterías solo deben ser sustituidas por el tipo Rohde & Schwarz correspondiente (ver lista de
recambios).
8. Las baterías y celdas deben reciclarse y no deben tirarse a la basura doméstica. Las baterías o
acumuladores que contienen plomo, mercurio o cadmio deben tratarse como residuos especiales.
Respete en esta relación las normas nacionales de eliminación y reciclaje.

1. El producto puede tener un peso elevado. Por eso es necesario desplazarlo o transportarlo con
precaución y, si es necesario, usando un sistema de elevación adecuado (p. ej. una carretilla
elevadora), a fin de evitar lesiones en la espalda u otros daños personales.
2. Las asas instaladas en los productos sirven solamente de ayuda para el transporte del producto por
personas. Por eso no está permitido utilizar las asas para la sujeción en o sobre medios de transporte
como p. ej. grúas, carretillas elevadoras de horquilla, carros etc. Es responsabilidad suya fijar los
productos de manera segura a los medios de transporte o elevación. Para evitar daños personales o
daños en el producto, siga las instrucciones de seguridad del fabricante del medio de transporte o
elevación utilizado.
3. Si se utiliza el producto dentro de un vehículo, recae de manera exclusiva en el conductor la
responsabilidad de conducir el vehículo de manera segura y adecuada. El fabricante no asumirá
ninguna responsabilidad por accidentes o colisiones. No utilice nunca el producto dentro de un
vehículo en movimiento si esto pudiera distraer al conductor. Asegure el producto dentro del vehículo
debidamente para evitar, en caso de un accidente, lesiones u otra clase de daños.
Eliminación
1. Si se trabaja de manera mecánica y/o térmica cualquier producto o componente más allá del
funcionamiento previsto, pueden liberarse sustancias peligrosas (polvos con contenido de metales
pesados como p. ej. plomo, berilio o níquel). Por eso el producto solo debe ser desmontado por
personal especializado con formación adecuada. Un desmontaje inadecuado puede ocasionar daños
para la salud. Se deben tener en cuenta las directivas nacionales referentes a la eliminación de

1 General Information
The Rohde & Schwarz FS-K40 application extends the functionality of the R&S FSP,
R&S FSU and R&S FSQ spectrum analyzers to enable phase noise measurements.
This manual supports the user in working with R&S FS-K40. It aids the preparation,
execution and evaluation of a measurement and gives many helpful hints and examples.
For the user wanting to make a quick start to using R&S FS-K40, the Quick Start Guide
section below works step-by-step through an ordinary phase noise measurement. The
remainder of this section describes all of the basic information about how the R&S FS-K40
application works, without covering phase noise measurements in detail. A detailed
description of all measurement modes, settings and results can be found in section 2.

1.1 Introduction to R&S FS-K40 & Phase Noise
Measurements
Phase Noise Measurement Software R&S FS-K40 extends the measurement capabilities
of Rohde&Schwarz spectrum analyzers to give a phase noise tester. The R&S FSP, R&S
FSU & R&S FSQ are ideal for this purpose because of their low inherent phase noise and
noise figure. The high phase noise measurement speed is achieved through the high sweep
rates of all analyzers. It is possible to trade off speed against accuracy at small resolution
bandwidths (M1 kHz) by using either FFT or digital filters. The software allows different
settings within a phase noise diagram, e.g. FFT close to the carrier and analog/digital filters
far off the carrier.
1.2 Installation
From the analyzer select firmware update.
1. Press the SETUP hardkey followed by NEXT, FIRMWARE UPDATE and finally the
FIRMWARE UPDATE softkey. Following the instructions displayed.
Once the installation has completed the analyzer will reboot.
Once the option has been installed it needs to be activated:

Setup of the softkey area
A softkey in its normal state, where its function is available, is coloured grey with a 3D
border.
A softkey that is disabled, because its function is not available, is coloured grey without
a 3D border. Softkeys may become disabled because of the state of the instrument or
because other settings disable the function associated with the softkey.
An active softkey (highlighted in green) is used when the softkey selects an item or
view. For example, the GENERAL SETTINGS softkey will be highlighted green when
the General Settings view is displayed.
A toggle softkey is used to change the value of a parameter that has only two states.
Each press of the softkey toggles the value of the parameter. The current parameter
value is highlighted in green in the lower half of the softkey label. For example, in the
marker menu, the MARKER softkey will have either NORM or DELTA highlighted in
green depending on whether the marker is a normal or delta marker.
When no function is assigned to a softkey then no softkey label will be shown.

If the Verify Frequency and Level parameter is selected in the General Settings
viewthen FS-K40 will
then check to see if there is a Signal within the specified Frequency and Level
Tolerance ranges relative to the specified Signal Frequency and Level. If no Signal is
found, or a Signal is found, which is outside the tolerance range then a message will
be displayed in the status bar (“No signals found within tolerance range”) and the
measurement will be aborted.
Whilst a measurement sweep is running, changing any of the setting in the General
Settings or Meas Settings views will cause the measurement to be aborted, apart from
the following settings:

Any parameters that are not available for editing will have a grey background. This usually
occurs when one parameter setting makes another parameter invalid, for example if the
Verify Frequency and Level is switched off then none of the parameters below this (Frequency
Tolerance and Level Tolerance) have any meaning, so these parameters are greyed out.
When a particular parameter is selected within the General Settings view the status bar
changes to display information about the valid settings for the selected parameter.

Measurements & Settings
R&S FS-K40
For a sweep count = 0 , a running average is calculated according to the following formula:
TRACE = 9 * TRACE + meas. value
10
Due to the weighting between the new measured value and the trace average, past
values have practically no influence on the displayed trace after about ten sweeps.
With this setting, signal noise is effectively reduced without need for restarting the
averaging process after a change of the signal. If the sweep count is >1, averaging
takes place over the selected number of sweeps. In this case the displayed trace is
determined during averaging according to the following formula:
n-1
TRACEn = 1/n
[
(Ti) + meas. valuen
]
i=1
where n is the number of the current sweep (n = 2 ... SWEEP COUNT). No averaging
is carried out for the first sweep but the measured value is stored in the trace memory.
With increasing n, the displayed trace is increasingly smoothed since there are more
single sweeps for averaging.
After the selected number of sweeps the average trace is saved in the trace memory.
Until this number of sweeps is reached, a preliminary average is displayed.
After completion of averaging, ie when the averaging length defined by SWEEP
COUNT is attained, a running averaging is continued with CONTINUOUS SWEEP
according to the following formula:
TRACE = (N – 1) * TRACEold + meas.Value
N
Where
Trace = new trace
Traceold = old trace
N = SWEEP COUNT
The display "N of N" does not change any more until a new start is triggered.
In the SINGLE SWEEP mode, the sweeps are stopped when the selected number of
sweeps is attained. The number of the current sweep and the total number of sweeps
are shown on the display: "3 of 200".

active traces in the selected diagram.
The setting of the sweep count in the trace menu is equivalent to the setting in the

Remote SENS:SWE:COUN 64
SMOOTHING
The SMOOTHING softkey is ON (the softkey is green), the trace on the screen will be
smoothed by the smoothing percentage (see general settings for noise). Toggling this
softkey will have an immediate effect on the active trace on display. Each trace (trace1,
trace2 and trace3) can be smoothed/unsmoothed individually.
The smoothing algorithm used is as follows:
Where: s = the trace sample number, y(s) = the phase noise at sample s, x = the
sample offset from s, and n = the width of the sliding window. When x exceeds the
boundary samples, the boundary sample is used, i.e. if the trace has samples
numbering 0 to 500 then with n = 5 and s = 0 the average is calculated as:
If both trace averaging and smoothing are specified then trace smoothing is applied
first, and averaging is performed on the smoothed trace.
When smoothing is applied to a trace, the original (unsmoothed) trace is still held in
memory. This makes it possible to toggle between a smoothed and unsmoothed trace
without the need to run a new measurement sweep.

ASCII FILE EXPORT
The ASCII FILE EXPORT softkey stores the active trace in ASCII format on a floppy
disk.
The file consists of the header containing important scaling parameters and a data
section containing the trace data.
The data of the file header consist of three columns, each separated by a semicolon:
parameter name; numeric value; basic unit
The data section starts with the keyword " Trace;<n>;" (<n> = number of stored trace),
followed by the measured data in two columns which are also separated by a
semicolon. The first column contains the frequency value, the second contains the
corresponding Phase noise value.
This format can be read in from spreadsheet calculation programs, eg MSExcel.
It is necessary to define ’;’ as a separator.
Different language versions of evaluation programs may require a different handling of
the decimal point. It is therefore possible to select between separators ’.’ (decimal
point) and ’,’ (comma) using softkey DECIM SEP.

3.1 Description of commands
This section specifies all the remote control commands specific to the R&S FS-K40
option. Only those commands provided for this option are specified. For details of
remote control commands provided by the host analyzer please refer to the analyzer
user manual.
3.1.1 Notation
In the following sections, all commands implemented in the instrument are first listed in
tables and then described in detail, arranged according to the command subsystems.
The notation is adapted to the SCPI standard. The SCPI conformity information is
included in the individual description of the commands.
Table of Commands
Command:
In the command column, the table provides an overview
of the commands and their hierarchical arrangement
(see indentations).
Parameter:
The parameter column indicates the requested
parameters together with their specified range.
Unit:
The unit column indicates the basic unit of the physical
parameters.
Comment:
In the comment column an indication is made on:
– whether the command does not have a query form,
– whether the command has only one query form
– whether the command is implemented only with a
certain option of the instrument
Indentations
The different levels of the SCPI command hierarchy are
represented in the table by means of indentations to the
right. The lower the level, the further the indentation to
the right. Please note that the complete notation of the
command always includes the higher levels as well.
Example: SENSe:FREQuency:CENTer is represented
in the table as follows:
Individual description
first level
SENSe
second level
:FREQuency
third level
:CENTer
The individual description contains the complete
notation of the command. An example for each
command, the *RST value and the SCPI information are
included as well.
Upper/lower case notation Upper/lower case letters are used to mark the long or short
form of the key words of a command in the description
Software Manual 1161.8209.42 - 04
63
Remote Control
R&S FS-K40
(see Section 3.5.2). The instrument itself does not
distinguish between upper and lower case letters.
Special characters
|
A selection of key words with an identical effect exists
for several commands. These keywords are indicated in
the same line; they are separated by a vertical stroke.
Only one of these keywords needs to be included in the
header of the command. The effect of the command is
independent of which of the keywords is used.
Example: SENSe:FREQuency:CW|:FIXed
The two following commands with identical meaning can
be created. They set the frequency of the fixed
frequency signal to 1kHz:
SENSe:FREQuency:CW
1E3
=
SENSe:FREQuency:FIXed 1E3
A vertical stroke in parameter indications marks
alternative possibilities in the sense of "or". The effect of
the command is different, depending on which
parameter is used.
Example: Selection of the parameters for the command
DISPlay:FORMat FULL | SPLit
If parameter FULL is selected, full screen is displayed, in
the case of SPLit, split screen is displayed.
[]
Key words in square brackets can be omitted when
composing the header (cf. Section 3.5.2, Optional
Keywords). The full command length must be accepted
by the instrument for reasons of compatibility with the
SCPI standards. Parameters in square brackets can be
incorporated optionally in the command or omitted as
well.
{}
Parameters in braces can be incorporated optionally in
the command, either not at all, once or several times.
Description of parameters
Due to the standardisation, the parameter section of
SCPI commands consists always of the same
syntactical elements. SCPI has therefore specified a
series of definitions, which are used in the tables of
commands. In the tables, these established definitions
are indicated in angled brackets (<...>) and will be briefly
explained in the following (see also Section 3.5.5,
"Parameters").
<Boolean>
This keyword refers to parameters which can adopt two
states, "on" and "off". The "off" state may either be
indicated by the keyword OFF or by the numeric value
0, the "on" state is indicated by ON or any numeric value
other than zero. Parameter queries are always returned
the numeric value 0 or 1.
<numeric_value>
<num>
Software Manual 1161.8209.42 - 04
These keywords mark parameters which may be
entered as numeric values or be set using specific
keywords (character data).The following keywords given
below are permitted:
64
Remote Control
R&S FS-K40
MINimum
This keyword sets the parameter to the
smallest possible value.
MAXimum
This keyword sets the parameter to the
largest possible value.
DEFault
This keyword is used to
parameter to its default value.
UP
This keyword increments the parameter
value.
DOWN
This keyword decrements the parameter
value.
The numeric values associated to
MAXimum/ MINimum/DEFault can be
queried by adding the corresponding
keywords to the command. They must be
entered following the quotation mark.
Example: SENSe:FREQuency:CENTer?
MAXimum
returns the maximum possible numeric
value of the center frequency as result.
reset

3.15 Status reporting registers
The status reporting system (see FIg. 23) stores all information on the present
operating state of the instrument, e.g. that the instrument presently carries out a
calibration and on errors which have occurred. This information is stored in the status
registers and in the error queue. The status registers and the error queue can be
queried via IEC bus.
The information is of a hierarchical structure. The register status byte (STB) defined in
IEEE 488.2 and its associated mask register service request enable (SRE) form the
uppermost level. The STB receives its information from the standard event status
register (ESR) which is also defined in IEEE 488.2 with the associated mask register
standard event status enable (ESE) and registers STATus:OPERation and
STATus:QUEStionable which are defined by SCPI and contain detailed information on
the instrument.
The IST flag ("Individual STatus") and the parallel poll enable register (PPE) allocated
to it are also part of the status reporting system. The IST flag, like the SRQ, combines
the entire instrument status in a single bit. The PPE fulfils the same function for the IST
flag as the SRE for the service request.
The output buffer contains the messages the instrument returns to the controller. It is
not part of the status reporting system but determines the value of the MAV bit in the
STB and thus is represented in

3.15.1 Description of the Status Registers
All the status registers shown in FIg. 23 are the same as those provided by the base
system, with the exception of the following:
STATus:OPERation – Although this register is provided by R&S FSP Kernel main,
R&S FS-K40 makes use of bit 4 in this register which are not used within R&S FSP
Kernel main
STATus:QUESTionable:ACPLimit – This register is provided by the analyser and is not
available from the R&S FS-K40 command tree
STATus:QUESTionable:LIMit2 – This register is provided by the analyser and is not
available from the R&S FSQ-K40 command tree

3.16 Error Reporting
Error reporting for the K40 option is carried out using the Service Request (SRQ)
interrupt in the GPIB interface. When an error occurs a Service Request interrupt will
be generated. The master can then query the slave instrument for the error that
triggered the interrupt Errors are queried through the “SYSTem:ERRor” command.

Status Bar Message
Description
Cannot run measurement - no traces are active
This message is displayed when all the traces are switched off or in
VIEW mode.
Set the trace mode of atleast one trace to be
CLRWRT/AVG/MAXHOLD/MINHOLD
No signals found within tolerance range
This message is only displayed when the Verify Frequency & Level
parameter is set in the General Settings view. This indicates that no
input signal could be identified within the supplied tolerances of the
specified frequency and level. Check that the Frequency and Level
parametes are set correctly. If further measurement executions give
this message then try increasing the frequency and/or level tolerance
ranges.
Frequency offset out of range:
This message is similar to the above, but is displayed after the initial
verification has been successfully performed and indicates that the
current subsweep is outside tolerance.
Level out of range:
