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 2000 m above sea
level, max. transport altitude 4500 m above
sea level.
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.

1171.0000.42-03.00 Sheet 2

Safety Instructions

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/operator 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
(corresponding to the 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. 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, 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 (higher fuse only after consulting with
the Rohde & Schwarz group of companies).

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

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

16. For measurements in circuits with voltages
V

> 30 V, suitable measures (e.g.

rms

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. 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.

be made first before any other connection
is made. The product may be installed and
connected only by a license 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

unless otherwise specified (see also safety
instruction 1.). If this is not taken into
account, there exists the danger of electric
shock for the user or damage to the
product, which can also lead to personal
injury.

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

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

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

Installing FS-K4 on PCs

FS-K4 is designed to work with Windows 9x (95, 98 and ME), Windows NT, Windows 2000 and
Windows XP. Please make sure that one of these operating systems is installed before continuing.

To control your Spectrum Analyzer from a PC us ing FS-K4, you must first install a G PIB interface card
in your computer, and then connect the PC and Spectrum Analyzer using a GPIB Cable. FS-K4
supports the following cards:

Supplier Model

Rohde & Schwarz PS-B4 model 04
National Instruments PCII/IIA, AT-GPIB/TNT (PnP ), AT-GPIB/TNT, PCI-GPIB, PCMCIA-GPIB

Rohde & Schwarz cannot guarantee or provide support for FS-K4 when used with any other
manufacturer's GPIB interface products.

Before running FS-K4 please use the setup and self -tes t sof tware, supplied with the card, to ensure that
all driver settings are set to their default 'f actory' condition, and that the board is functioning correctly.
Please consult the documentation supplied with the card to learn how to do this.

FS-K4 Software Setup

To install FS-K4, proceed as follows:

1. Start Microsoft Windows

It is strongly recommended that you exit all Windows programs that may be running now.
This includes anti-virus software, office suite toolbars, information management software,

FS-K4 Installation Instructions

Installing FS-K4 on FSIQ, ESIB and FSE with FSE-B15 Option

If your spectrum analyzer (FSIQ, ESIB or FSEx with FSE-B15) is s uitably configured, no ex ternal PC will
be required for phase noise measurements and your analyzer will constitute an independent phase
noise test set.

FS-K4 is designed to work with firmware version 2.x or higher. If your Spectrum Analyzer is fitted with an
earlier version, please ask your Rohde & Schwarz representative to arrange for an upgrade.

If you want to run FS-K4 on your FSE Spectrum Analyzer, you must have the FSE-B15 Computer
Option fitted. If you do not already have this option, please ask your Rohde & Schwarz representative for
details.

The installation of the FS-K4 described below requires the administrator login. The user name is
"Administrator", the password for the administrator login is 894129 for the instrument.

On power-up following the installation under the administrator identification, the NT login window is
displayed (no autologin). The user nam e entry is to be replaced by "instrument" and "instr ument" as the
according password. This change re-enables the autologin.

FS-K4 Software Setup

To install FS-K4 on the FSIQ, ESIB or FSE with FSE-B15 option proceed as follows:

1. First connect the keyboard and mouse, and turn on the spectrum analyzer

2. Wait until the spectrum analyzer has initialized

3. Press the ALT and Print Screen/Sys Rq k eys together. The analyzer display will switch to computer
mode, showing the Windows screen

4. Insert the installation disk in drive A.

5. Now follow the same instructions as described in “Installing FS-K4 on PCs” sub-section “FS-K4
Software Setup” from step 3.

Note: You can switch the display back to Spectrum Analyzer mode, by pressing ALT + Print

Screen again.

1108.0107.42 11 E-6

Installation Instructions FS-K4

Installing FS-K4 on FSQ, FSU, FSP or ESPI Analyzers running Windows NT

If your FSQ, FSU, FSP or ESPI analyzer is suitably configured, no external PC will be required for phase
noise measurements and your analyzer will constitute an independent phase noise test set.

To install and operate the FS-K4 software a PS/2 keyboard is necessary e.g. PSP-Z2 (Order No.

1091.4100.02). When using other type of keyboards without built-in roll-key it is recommended to

connect a PS/2 mouse to the rear of the analyzer. Do not connect keyboard and mouse with the power
switched on.

Prior to the installation of FS-K4 the internal connections between FS-K4 and the analyzer must be
ensured:

• Installation of network card driver (with built-in option FSP-B16 this is already included in the
installation of option)

• Installation of TCP/IP network protocol

• Installation of RSIB interface libraries.

Note: The WINDOWS NT files required for the installation of network drivers, protocols and

services are located in the "C:\I386" directory.

Installation of the netw ork card driver for analyzers without the LAN interface option

The basic prerequisite f or the installation of the TCP/IP pr otocol is that a network card dr iver is built in.
In the absence of such a card a so-called loopback adapter takes over for the missing func tion. The
adapter is part of the Windows NT.

The installation procedure is as follows after the power-up of the analyzer and start of the firmware:

¾ Open the start menu of Windows NT with the key combination <CTRL>-<ESC> .
¾ Select menu items SETTINGS – CONTROL PANEL – NETWORK.

¾ Answer the question "Do you want to

install it now?" with "Yes".

FS-K4 How to Use FS-K4

2 How to Use FS-K4

When measuring with FS-K4 there are three basic steps to work through:

1. Creating an Analyzer Setup, i.e., defining the sweep parameters and, if required, the limit line (p23),

2. Making a Measurement, i.e., performing the sweep, analyzing and storing the results (p27),

3. Generating a Report (p29)

Creating an Analyzer Setup

A complete Analyzer Setup consists of the following components:

1. Sweep Setup Defines how each measurem ent should be made suc h as signal fr equency and
level, offset start and stop f requencies, display reference level and range, and
report configuration.

2. Limit Line Defines the maximum allowed noise level for each frequency in the
measurement band.

In order to make a measurement you must have a Sweep Setup, however the Limit Line is optional.
You can load these components using any combination of the following methods:

1. Creating New Setup Files (p23)

2. Loading an Existing File (p25)

Once you have assembled and activated the necessary files in memory you can store the complete
Analyzer Setup for later re-use, see Saving a File (p26).

Creating New Setup Files

Before starting to make measurements with FS-K4 you should build a library of setup files. Sweep Setup
files are dependent on Limit Line files, so you should create them in the order shown below.

1. Creating a New Limit Line (p23)

2. Creating a New Sweep Setup (p24)

Each Sweep Setup file will also contain an embedded copy of any Limit Line file that it uses.

Note: When measurement results are saved, copies of all the files used to make the

measurement are stored in the result data file. In this way future examination of res ults will
remain independent of any setup file modifications that occur after a measurement is made.

Creating a New Limit Line

To create a new limit line:

1. Choose New (p31) from the file menu.

2. Select Limit Line in the New box.

3. If you want to base the new limit on an existing one, choose a file name in the Template box. To help

you, the description of the selected file name is displayed in the Description box.

4. Otherwise if want to create a new limit from scratch, choose none in the Template box.

5. Choose the OK button to load the selected template and open the Limit Line (p39) editor.

6. If you have chosen to work with a template f ile, it will be displayed in the editor. Otherwise, the editor

will be empty.

1108.0107.42 23 E-6

How to Use FS-K4 FS-K4

7. First, enter a name for the new limit line in the Nam e box. T his nam e is used to create the file nam e

for the limit when stored to disk . Thus it is restricted to eight character s in length and m ay consist
only of characters which may be used in a DOS file name.

8. Now enter limit line samples into the Values table entry box.

9. To enter a new fr equency in the left hand column of the table, move the highlight to the correct cell

and type the new value. To specify a unit of measurement, append Hz, kHz, MHz or GHz to the
value. In each case, the f ir st letter is suf ficient in either upper or lower case. To ac cept the new value
either click on the tick button, or press the T AB key, or press the ENTER key. To reject the new
value and retain the old one either click on the cross button, or press the ESCAPE key.

Note: The

ENTER and ESCAPE only behave as described above when the ins ertion point appears

in the value entry box to the right of the tick button. Normally, the
the highlighted button and the

ESCAPE key corresponds to the Cancel button.

ENTER key corresponds to

1. To enter a new level in the right hand column, simply move to the correct row, type the value in

dBc/Hz and accept it. There is no need to enter the unit of measurement.

2. You must enter at least two samples in ascending order of frequency with the lowest frequency at the

top of the table. The total number of samples entered is shown by the Samples field.

3. If you enter an illegal or out-of-range value, a message will be displayed in the Status Bar (p54)

showing the range of acceptable values

4. If you did not load a template file, choose the Activate button to turn the limit line on.

5. Finally, choose the OK button to confirm the new limit line.

You can store the new limit line for later re-use, see Saving a File (p26).

Creating a New Sweep Setup

To create a new Sweep setup:

1. Choose New (p31) from the file menu.

2. Select Analyzer Setup in the New box.

3. If you want to base the new setup on an existing one, choose a f ile name in the Template box. T o

help you, the description of the selected file name is displayed in the Description box.

4. Otherwise if you want to create a new setup from scratch, choose none in the Template box

5. Choose the OK button to load the selected template and open the Sweep Setup (p35) editor.

6. If you have chosen to work with a template f ile, it will be displayed in the editor. Otherwise, the editor

will be pre-set to the default setup for the current Analyzer type.

7. First choose the Analyzer type and options with which the new setup will be used. This controls the

range of frequencies that may be used, and the availability of FFT Filters..

8. Enter the frequency of the c arrier you wish to measur e in the Signal Frequenc y box. You can specify

the unit by appending GHz, kHz, MHz or GHz. In each case, the first letter is sufficient in either upper
or lower case.

9. In the Signal Level box, enter the magnitude of the carrier in dBm. This value is used to set the

analyzer reference level.

10. If you do not know the precise frequenc y of the carrier you wish to measure, select the Verify Signal

Frequency and Level box. This enables a search, within a defined f requency tolerance range re lative
to the specified Signal Frequency, for the carr ier of greatest magnitude. T he frequency and level of
this carrier are then accur ately measured. If the resultant level is less that the specified Signal Level
less a defined Level Tolerance, the m easurement is aborted. Otherwise, the resultant frequency is
used in place of the specified Signal F requency, and the measured level is used to set the analyzer
reference level, overriding the value specified in the Signal Level box.

11. If enabled, enter a value in the Frequency Tolerance box. This def ines the offset, either side of the

specified Signal Frequency, within which the carrier is guaranteed to be. FS-K4 will search for a
carrier between Signal Frequency - Frequency Tolerance and Signal Frequency + Frequency
Tolerance.

1108.0107.42 24 E-6

FS-K4 How to Use FS-K4

12. If enabled, enter a value in the Level Tolerance box. T his defines the off set relative to the specified

Signal Level above which the carrier is guaranteed to be.

13. The Minimum Offset and Maximum Offset boxes allow you to select the range of frequencies to

measure. Each contains a list of positive offsets from the carrier. The Maximum Offset must be
greater than the Minim um Off set, and the Signal Frequenc y + Maximum Of fset m ust be les s than or
equal to the maximum frequency of the analyzer.

14. T he Max imum Level and Level Range boxes ref er to F S-K4’s Gr aph rather than the analyzer display.

The Maximum Level is specified in dBc/Hz since the displayed data is normalized to the carrier level.

15. The trace may be offset by a fixed number of dBs entered in the Trace Offset box.

16. Optionally the trace may also be smoothed by calculating the average of samples in a sliding

window, see Smoothing Window in Sweep Setup (p35) for details.

17. Choose the Report button to display the Report Setup (p37) dialogue box. This allows you to set

initial values for various report text f ields, and select which elements of the report to include. Once
these values are set, choose the OK button to accept any changes

18. In special circumstances you can further optimize the measurement by modifying the parameters

shown in the Advanced Sweep Setup ( p37) dialogue box . T o open this choos e the Advanced button,
then once new values have been set, choose the OK button to accept any changes.

19. Choose the OK button in the Sweep Setup dialogue box to confirm the new Sweep setup.

Loading an Existing File

To load an existing file from disk:

1. Choose Open (p31) from the file menu.

2. If you wish to load a file from a default dir ectory, as defined in the Default Paths (p48) dialogue box,

6. Select the drive containing the file you want to load in the Drives box.

7. Select the directory containing the file you want to load in the Directories box.

8. Type the name of the file you want to load in the File Descr iption box or select it in the file list box

below.

9. Choose the OK button to confirm your selection and load the file.

10. If loading the c hos en f ile will aff e ct any unsaved changes to the files in memor y, FS-K4 will ask if you

want to save the changes. You will be asked this question f or eac h m odified f ile, and if you decide to
save a modified file the Save As (p32) dialogue box will be displayed.

11. If ther e is measured data in memory and loading the chos en f ile will direc tly affec t the way in which a

measurement is made, FS-K4 will warn you that all measured data will be discarded.

Exactly how the contents of memory gets changed depends on the type of file loaded as shown in the
table below:

1108.0107.42 26 E-6

FS-K4 How to Use FS-K4

Making a Measurement

Measuring with FS-K4 consists of three steps:

1. Making a Sweep Measurement (p27)

2. Using the Marker menu commands for Analyzing Sweep Results (p28)

3. Storing the results for later re-use, as described in Saving a File (p26).

In cases where the phase noise of the unit under test is comparable to the inherent phase noise of the
analyzer, a two stage measurement may be used to improve the accuracy of the final result.

To make a two stage measurement:

1. First connect a reference source to the analyzer.

2. Make a Sweep Measurement as described above.

3. Choose Trace to Reference (p44) from the Sweep menu to copy the trace into the reference buffer.

4. Now connect the unit under test.

5. Make a second Sweep Measurement.

6. Choose Corrected (p41) from the View menu.

7. T he application will perform a linear subtraction of the refer ence trace from the uncorrected trace,

and plot the result.

Once a two stage measurement is complete you can

• Switch back to the uncorrected trace by choosing Uncorrected (p41) from the View menu.

• Display the reference trace by choosing Reference (p41) from the View menu. The Normal and Delta

marker displays will change to inc lude calculated level of fsets f rom the mar ker level to the r eferenc e
trace.

To stop using the Reference Trace:

• Choose Clear Reference (p44) in the Sweep menu.

Making a Sweep Measurement

To run a Sweep:

• Choose Start (p43) from the Sweep menu.

The Analyzer will be configured according to the current Analyzer Setup. If this fails, an information
dialogue will be displayed describing the problem and the measurement will be aborted.

If the Verify Frequency and Level f unc tion is s elec ted in the Sweep Setup (p35) dialogue box, F S-K4 will
then check to s ee if ther e is a Signal within the spec if ied F requenc y and Level Toleranc e ranges re lative
to the specified Signal Frequency and Level. If no Signal is f ound, or a Signal is f ound, which is outside
the tolerance range, an information dialogue will be displayed describing the problem, and the
measurement will be aborted.

After a short delay the Analyzer will start measuring and automatic ally uploading the Sweep results to
the computer. The Status Bar (p54) message changes to read "Sweep running...(0%)", and as data is
received the value inside the parentheses is updated to show the ratio of sam ples received to the total
expected, expressed as a percentage.

The overall sweep is divided into a number of sub-bands, which are measured separately. This is
optimized to provide the best combination of measurement accuracy and speed.

1108.0107.42 27 E-6

How to Use FS-K4 FS-K4

If the Graph is visible, data will be plotted as soon as it is received. In many cases, the Sweep will
generate more sam ples than can be displayed. A data reduction algorithm is used to ensure that the
level represented by each pixel column in the displayed trace represents the max imum value measured
for the band of frequencies it represents. This data reduction process does not affect the raw data
uploaded from the Analyzer; which may be viewed, once the sweep is complete, by zooming in until
every pixel column represents a single raw data sample. FS-K4 can store up to 20,000 samples in
memory.

If the RF Overload warning is activated whilst measuring a sub-band, the input attenuation will be
increased by 10dB and the sub-band will be re-measured.

If the sweep cannot be completed f or any reason, an information dialogue will be displayed describing
the problem and the measurement will be aborted.

Whilst the sweep is in progress you can:

1. Use the Normal (p45) and Delta (p45) Mark ers. T hese m ay be turned on using the com m ands in the

Marker menu and m oved along the trac e using either the k eyboard cursor keys, or by positioning the
mouse pointer and then clicking the left mouse button.

2. Abort the sweep by choosing Stop (p43) from the Sweep menu. An information dialogue will be

displayed confirming this action and the measurement will be aborted.

Analyzing Sweep Results

The Marker menu provides a number of tools to help you examine the phase noise trace.

1. The Normal (p45) marker displays the phase noise level measured at a specific frequency.

2. The Delta (p45) marker displays the offset frequency and level relative to the Normal marker.

3. When the Delta m ark er is enabled, Next Marker (p45) allows you to select which m ark er ’s f requency

may be varied using the mouse and/or cursor keys.

4. Use the Measure at Marker (p45) command in the Mark er menu to re-measure phase nois e at the

current marker frequency.

5. T he Zoom function allows you to view the Sweep r esults in greater detail, ultim ately rem oving the

effects of data compression so that the raw data is displayed.
If the marker is in Normal mode, the Zoom In (p45) command will redr aw the Graph, changing the

frequency span to show one tenth of the previous span, center ed on the mark er fr equency. Zoom In
may be used repeatedly until only raw data is displayed, with no data reduction. Zoom Out (p46) has
the opposite effect, increasing the span by a factor of ten centered on the marker, whilst
Original Diagram (p46) returns the display to the span defined by the Sweep Setup.

When the marker is in Delta m ode, Zoom In changes the span to show frequencies between the
reference and delta markers.

In addition, the View menu provides three ex tra com m ands for displaying calculated values for Residual
Phase Modulation, Residual Frequency Modulation, and RMS Jitter respectively. When the Delta
marker is enabled, the calculation is perfo rm ed on the m easur ed values lying between the two marker s.
Otherwise, all measured values are taken into account.

Frequency

Enter the frequency of the carrier whose phase noise you wish to measure.
Specify the unit by appending GHz, kHz, MHz or GHz. In eac h case, the first letter is sufficient in
either upper or lower case.

Level

Magnitude of carrier in dBm.

Verify Frequency

Enables a search, across a frequency tolerance range, for the carrier of greatest magnitude.
Resultant carrier frequency and level are m easured. If the level is within a level tolerance range,
the measured values override the specified Signal Frequency and Level. Otherwise the
measurement is aborted.
This should be used when carrier frequency is not known precisely and when a very small
Minimum Offset is used.

1108.0107.42 35 E-6

Menu Commands FS-K4

Frequency Tolerance

Range, either side of Signal Frequency, within which the carrier is known to be.
Specify unit as for Frequency.

Level Tolerance

Offset relative to Signal Level above which the carrier is know to be.

Display

X-Axis
Minimum Offset

Select the offset at which to start the sweep.

Maximum Offset

Select the offset at which to finish the sweep.

Y-Axis
Maximum Level

Enter the value you want at the upper extent of the Graph’s level axis. Phas e Noise levels are
normalized to the carrier level and expressed in dBc/Hz.

Level Range

Enter the range of values you want for the Graph’s level axis in dB.

Tools
Trace Offset

Enter any fixed offset in dB. This value will be added to each measured value.

Smoothing Window

The trace may be smoothed by calculating the linear average of sample values in a sliding
window. Enter the width of the window as a number of samples.
The width must be a positive, odd, integer, less than 200, i.e. 0 < n < 200, n mod 2 = 1. The
default value of 1 turns smoothing off.
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:

FS-K4 Menu Commands

Sweep Menu

The Sweep menu comprises the com mands used for st arting and terminating a measurem ent and for
storing and deleting the reference trace.

Start command (Sweep Menu)

Use this command to begin a new Sweep measurement using the current Analyzer Setup file.

Note: Any displayed Sweep results will be cleared by this command.

FS-K4 starts by configuring the analyzer according to the current Analyzer Setup. If for any reason the
Analyzer does not respond, an error message will be displayed describing the problem. See
Communication Problems (p65) for more information.
If the Verify Frequency and Level f unc tion is s elec ted in the Sweep Setup (p35) dialogue box, F S-K4 will
then check to s ee if ther e is a Signal within the spec if ied F requenc y and Level Toleranc e ranges re lative
to the specified Signal Frequency and Level. If no Signal is f ound, or a Signal is f ound, which is outside
the tolerance range, an information dialogue will be displayed describing the problem, and the
measurement will be aborted.
As soon as the Sweep starts, "Sweep running... (0%)" will appear in the Status Bar. The perc entage
indicator will increase each time a new bloc k of data is dis played and is calculated as the ratio of values
received to total values expected.
The overall sweep is divided into a number of sub-bands, which are measured separately. This is
optimized to provide the best combination of measurement accuracy and speed. If the RF Overload
warning is activated whilst m easuring a sub-band, the input attenuation will be increased by 10dB and
the sub-band will be re-m easured. If the sweep cannot be completed for any reason, an information
dialogue will be displayed describing the problem and the measurement will be aborted.
Once the Sweep is finish, "Sweep complete" appears in the Status Bar.

Stop command (Sweep Menu)

Use this command to terminate a Sweep measurement.
"Sweep aborted" will appear in the Status bar (p54), an information dialogue will be displayed confirming
the action, and FS-K4 will stop the Sweep.

Mode command (Sweep Menu)

Use this com mand to switch repetitive Sweeping on and off and also to choose between Graph ( p55)
display modes Clear/Write and Max. Hold.
A sub-menu appears when this command is selected with the following options:

Clear/Write

Use this command to disable repetitive Sweeping and select Clear/Write display mode.
The Sweep will then end at the stop frequency of the Sweep.
A check mark appears next to the command name when this mode is selected.

Repeat Clear/Write

Use this command to enable repetitive Sweeping in the Clear/Write display mode.
The Sweep will then automatically re-start each tim e the Analyzer reaches the stop frequency of
the Sweep. In Clear/Write m ode, the Graph panel displays only those values measured during
the current pass.
A check mark appears next to the command name when this mode is selected.

1108.0107.42 43 E-6

Menu Commands FS-K4

Repeat Max. Hold

Use this command to enable repetitive Sweeping in the Max. Hold display mode.

The Sweep will then automatically re-start each tim e the Analyzer reaches the stop frequency of
the Sweep. In Max. Hold mode, the Graph displays the maximum value measured at each
frequency during all passes since the Repeat Max. Hold command was used.
A check mark appears next to the command name when this mode is selected.

Trace to Reference command (Sweep Menu)

Use this command to copy the main Sweep trace into the Reference Trace Buffer.
You can then make a new measur ement or load an exis ting Result Data file and com pare the traces in
the following ways:

• use the Reference (p41) command in the View menu to display the reference with the main
trace then,

• use the Graph (p55) panel to compare them visually or

• use the Markers (p56) to compare them point by point or

• use the Corrected (p41) command in the View menu to display the calculated difference

between the main and reference traces.

Note: Both traces must be measured using the same Analy zer setup. The reference tr ace will be

cleared as soon as an incompatible setup is loaded.

Use this command to toggle control of marker frequency between the Normal and Delta markers.

Measure at Marker command (Marker M enu) )

Use this command to measure phase noise using the analyzer’s Phase Noise Marker at the current
marker frequency.
If the mar ker frequency is not between the analyzer’s current start and stop f requencies, the sub-band
containing it will be swept first using the current Analyzer Setup parameters.
This command provides a convenient method for checking Phase Noise at spot frequencies.

Note: This command is disabled whilst a Sweep measurement is running.

Zoom In command (Marker Menu) )

Use this command to magnify a selected portion of the measured spectrum displayed by the Graph
(p55).

This may be us ed when more values have been m easured than can be represented on the horizontal
axis due to insuf ficient display resolution. The frequency axis of the Gr aph is expanded and all traces
and the limit lines are redrawn. The level axis is not affected.
You can use the Zoom In c ommand repeatedly until all detail is visible at which point the comm and is
disabled.
The frequency range covered by the zoom function depends on the marker mode:

Normal (p45) T he frequency axis is expanded to show 10% of the dis play width

centered on the current mark er frequenc y. In the vicinity of the start
and stop frequencies the software performs an adaptation.

Analyzer command (Options Menu)

Use this command to modify the default Analyzer type, address and start-up conditions.

Note: At st artup, FS-K4 will check to see if the analyzer it was las t used with is present. If not, it

checks to see if it is running on the analyzer itself. It this fails, it checks each GPIB address.

• If no analyzer is found, FS-K4 assumes that you will connect an analyzer later, and selects the
analyzer type used most recently as the default.

• If FS-K4 is running on the analyzer, it selects the internal, DDE communications method, which
bypasses the GPIB, and sets this analyzer and communications method as the new default.

• Finally, if an analyzer is found at a GPIB address, it is selected as the new default.

This comm and allows you to override these settings when an analyzer is connected to the bus after
startup.

Dialogue Box Options

Use DDE

When FS-K4 is run on the analyzer, this enables control of the analyzer without using the GPIB.

Use GPIB

When FS-K4 is not run on the analyzer, this enables control of the analyzer using the GPIB.

Address

Select the bus addres s of the Analyzer you want to work with. If the analyzer is connected and
turned on when you start FS-K4, this value will be set automatically.

Log Text Files

Each time a new sweep measurem ent is started, the log is cleared. FS-K4 then tries to initialize the
analyzer and will log the result, for example:

Initialization
==============

Analyzer type FSEB 30+B2+B4+B5 initialized successfully.

If the Carrier Search function is enabled, its results will appear next. The analyzer sweeps a span of
twice the Frequency Tolerance, centered on the Signal Frequency specified in the Sweep Setup
dialogue. If the peak exceeds the reference level, the reference level is increased by 10dB and the
sweep repeated. The peak is then accur ately measured using the frequency counter and marker. For
example:

Carrier search starting
=======================

Center 100 MHz, Span 2 kHz
RBW 2 kHz, Reference level -15.00 dBm
Sweep, Max Hold x 1, result OK
Peak found at 50.0000661 MHz, 2.94 dBm

Sweep, ClearWrite x 1, result OK
Carrier found at 149.9999939 MHz, 2.94 dBm

If no Signal is found or if the Signal is outside the specified tolerances, the measurement will be aborted.
The Reference Level and any Level Offset to be us ed during the Phase Nois e sweep are then logged,
for example:

Ref. Level will be set to 2.94 dBm for offsets less than 10 kHz.
Ref. Level will be set to -17.06 dBm for offsets greater than 10 kHz

Level Offset is 0.00 dB

Input attenuation is norm ally calculated to obtain a signal level of up to +5dBm at the m ixer input for
offsets greater than 10 k Hz. However since the f requenc y response of the f ront end is not guaranteed to
be flat, it is nec essary to check whether any additional attenuation will be required for offsets from 10
kHz to 100 MHz. Above this, the carrier is well outside the edges of the resolution bandwidth filter and
not additional attenuation is required.

A check is made to see if the RF O verload warning is ac tivated with the calculated input attenuation. If it
is activated, the attenuation is increased in 10dB steps until the overload is removed.

RF Overload Check starting
==========================

1108.0107.42 72 E-6

FS-K4 Data Storage Format

Input Attenuation set to 0 dB
Sweep, Average x 1, result *** RF Over Range ***
Input Attenuation set to 10 dB
Sweep, Average x 1, result OK

Attenuation will be offset by 10 dB, in the range 10 kHz to 100 MHz

The Phase Noise measurem ent then s tarts. T he overall sweep is divided into one or m ore sub-sweeps
depending on the specified start and stop offsets. For each sub-sweep the following information is
logged:

Start Decade Number Sub-sweep within decade
Absolute Start Frequency Absolute Stop Frequency
Resolution Bandwidth Video Bandwidth
Main PLL Bandwidth Input Attenuation
Reference level Normalization Factors

In addition the analyzer’s Phase Noise Marker is used to meas ure at six points equally spaced across
the sub-band and the results are listed along with the results from the sub-band and the computed
difference. For example:

Sweep 1, Start Decade = 3, Sub-band = 1
Offsets 1kHz to 10kHz relative to 149.9999939MHz

RBW set to 200Hz
PLL Bandwidth set to HIGH, FFT Filter is ON
Input Attenuation set to 20 dB
Reference level set to 2.90 dBm
Sweep, Average x 1, result OK

Normalization factors for Model 7

---------------------------------­ RBW = 200Hz , => 23.01 dB
