Preparing for Use

Windows Operating System

2.2 Windows Operating System

The instrument contains the Windows 7 operating system which has been config­ured according to the instrument's features and needs. Changes in the system
setup are only required when peripherals like keyboard or a printer are installed
or if the network configuration does not comply with the default settings. After the
R&S FSW is started, the operating system boots and the instrument firmware is
started automatically.

To ensure that the instrument software functions properly, certain rules must be
adhered to concerning the operating system.

Risk of causing instrument unusability

The instrument is equipped with the Windows 7 operating system. Addi­tional software can therefore be installed on the instrument. The use and
installation of additional software may impair instrument function. Thus, run
only programs that Rohde & Schwarz has tested for compatibility with the
instrument software.

The drivers and programs used on the instrument under Windows 7 have
been adapted to the instrument. Existing instrument software must always
be modified using only update software released by Rohde & Schwarz.

The following program packages have been tested:

R&S Power Viewer Plus - virtual power meter for displaying results of the

●

Power Sensor R&S NRP-Zxx (install only this component!)
Symantec Endpoint Security – Virus-protection software

●

FileShredder - for reliable deletion of files on the hard disk

●

2.2.1 Virus Protection

Users must take appropriate steps to protect their instruments from infection.
Beside the use of strong firewall settings and regularly scanning any removable
storage device used with a Rohde & Schwarz instrument, it is also recommended
that anti-virus software be installed on the instrument. While Rohde & Schwarz
does NOT recommend running anti-virus software in the background ("on-

access" mode) on Windows-based instruments, due to potentially degrading
instrument performance, it does recommend running it during non-critical hours.

For details and recommendations, see the Rohde & Schwarz White Paper "Mal­ware Protection" available at http://www.rohde-schwarz.com/appnote/1EF73.

2.2.2 Service Packs and Updates

Microsoft regularly creates security updates and other patches to protect Win­dows-based operating systems. These are released through the Microsoft Update
website and associated update server. Instruments using Windows, especially
those that connect to a network, should be updated regularly.

For more details and information on configuring automatic updates see the R&S
White Paper "Malware Protection" (available at http://www.rohde-schwarz.com/

appnote/1EF73).

2.2.3 Login

Windows 7 requires that users identify themselves by entering a user name and
password in a login window. By default, the R&S FSW provides two user
accounts: an administrator account ("Instrument") with unrestricted access to the
computer/domain, and a standard user account ("NormalUser") with limited
access. In both cases the initial password is 894129. Note that this password is
very weak, and it is recommended that you change the password for both users
after initial login. You can change the password in Windows 7 for any user at any
time via "Start > Control Panel > User Accounts".

Secure User Mode

If the secure user mode option (R&S FSW-K33) is installed, an additional
account is provided: the "SecureUser", also with the password 894129.

When the secure user mode is activated the first time after installation, the
user is prompted to change the passwords for all user accounts in order to
improve system security.

For details see chapter 2.7, "Protecting Data Using the Secure User Mode",
on page 31.

For the administrator account, an automatic login function is active by default. If
activated, login is carried out automatically for the administrator (with full access)

Installing USB devices is easy under Windows, because all USB devices are
plug&play. After a device is connected to the USB interface, automatically
searches for a suitable device driver.

Preparing for Use

If Windows does not find a suitable driver, it will prompt you to specify a directory
that contains the driver software. If the driver software is on a CD, connect a USB
CD-ROM drive to the instrument before proceeding.

When a USB device is subsequently disconnected from the R&S FSW, Windows
immediately detects the change in hardware configuration and deactivates the
corresponding driver.

All USB devices can be connected to or disconnected from the instrument during
operation.

Connecting a memory stick or CD-ROM drive

If installation of a memory stick or CD-ROM drive is successful, Windows informs
you that the device is ready to use. The device is made available as a new drive
and is displayed in Windows Explorer. The name of the drive depends on the
manufacturer.

Connecting a keyboard

The keyboard is detected automatically when it is connected. The default input
language is English – US.

However, you can also connect foreign language keyboards; currently the follow­ing languages are supported for the R&S FSW:

German

2.5 Setting Up a Network (LAN) Connection

The R&S FSW is equipped with a network interface and can be connected to an
Ethernet LAN (local area network). Provided the appropriate rights have been
assigned by the network administrator and the Windows firewall configuration is
adapted accordingly, the interface can be used, for example:

To transfer data between a controlling device and the test device, e.g. in order

●

to run a remote control program.
See chapter "Remote Control" in the R&S FSW User Manual.

To access or control the measurement from a remote computer using the

●

"Remote Desktop" application (or a similar tool)
To connect external network devices (e.g. printers)

●

To transfer data from a remote computer and back, e.g. using network folders

●

This section describes how to configure the LAN interface. It includes the follow­ing topics:

chapter 2.5.1, "Connecting the Instrument to the Network", on page 26

●

chapter 2.5.2, "Assigning the IP Address", on page 27

●

Note that only user accounts with administrator rights can configure LAN net­works.

LXI

The R&S FSW complies with LXI Class C. LXI gives you direct access to
the LAN settings described below.

For further information on the LXI interface refer to the User Manual.

R&S®FSW

Preparing for Use

Setting Up a Network (LAN) Connection

2.5.1 Connecting the Instrument to the Network

There are two methods to establish a LAN connection to the instrument:

A non-dedicated network (Ethernet) connection from the instrument to an

●

existing network made with an ordinary RJ-45 network cable. The instrument
is assigned an IP address and can coexist with a computer and with other
hosts on the same network.

A dedicated network connection (Point-to-point connection) between the

●

instrument and a single computer made with a (crossover) RJ-45 network
cable. The computer must be equipped with a network adapter and is directly
connected to the instrument. The use of hubs, switches, or gateways is not
required, however, data transfer is still performed using the TCP/IP protocol.
An IP address has to be assigned to the instrument and the computer, see

chapter 2.5.2, "Assigning the IP Address", on page 27.

Note: As the R&S FSW uses a 1 GBit LAN, a crossover cable is not neces-
sary (due to Auto-MDI(X) functionality).

Risk of network failure

Before connecting the instrument to the network or configuring the network,
consult your network administrator. Errors may affect the entire network.

► To establish a non-dedicated network connection, connect a commercial

RJ-45 cable to one of the LAN ports.
To establish a dedicated connection, connect a (crossover) RJ-45 cable
between the instrument and a single PC.

If the instrument is connected to the LAN, Windows automatically detects the net­work connection and activates the required drivers.

The network card can be operated with a 1 GBit Ethernet IEEE 802.3u interface.

R&S®FSW

Preparing for Use

Setting Up a Network (LAN) Connection

2.5.2 Assigning the IP Address

Depending on the network capacities, the TCP/IP address information for the
instrument can be obtained in different ways.

If the network supports dynamic TCP/IP configuration using the Dynamic Host

●

Configuration Protocol (DHCP), all address information can be assigned auto­matically.

If the network does not support DHCP, or if the instrument is set to use alter-

●

nate TCP/IP configuration, the addresses must be set manually.

By default, the instrument is configured to use dynamic TCP/IP configuration and
obtain all address information automatically. This means that it is safe to establish
a physical connection to the LAN without any previous instrument configuration.

Risk of network errors

Connection errors can affect the entire network. If your network does not
support DHCP, or if you choose to disable dynamic TCP/IP configuration,
you must assign valid address information before connecting the instrument
to the LAN. Contact your network administrator to obtain a valid IP address.

Assigning the IP address on the instrument

1. Press the SETUP key.

2. Press the "Network + Remote" softkey.

3. Select the "Network" tab.

4. In the "Network + Remote" dialog, toggle the "DHCP On/Off" setting to the

required mode.
If DHCP is "Off", you must enter the IP address manually, as described in the
following steps.
Note: When DHCP is changed from "On" to "Off", the previously set IP
address and subnet mask are retrieved.
If DHCP is "On", the IP address of the DHCP server is obtained automatically.
The configuration is saved, and you are prompted to restart the instrument.
You can skip the remaining steps.
Note: When a DHCP server is used, a new IP address may be assigned each
time the instrument is restarted. This address must first be determined on the
instrument itself. Thus, when using a DHCP server, it is recommended that

27Getting Started 1312.9420.02 ─ 15

R&S®FSW

Setting Up a Network (LAN) Connection

you use the permanent computer name, which determines the address via the
DNS server (see "Using a DNS server to determine the IP address"
on page 28 and chapter 2.5.3, "Using computer names", on page 29).

5. Enter the "IP Address", for example 192.0.2.0. The IP address consists of four

number blocks separated by dots. Every block contains 3 numbers in maxi­mum.

6. Enter the "Subnet Mask", for example 255.255.255.0. The subnet mask con-

sists of four number blocks separated by dots. Every block contains 3 num­bers in maximum.

7. Select "Configure Network".

If you have entered an invalid IP address or subnet mask, the message "out of
range" is displayed in the status line. If the settings are correct, the configura­tion is saved, and you are prompted to restart the instrument.

8. Confirm the displayed message ("Yes" button) to restart the instrument.

Preparing for Use

Using a DNS server to determine the IP address

If a DNS server is configured on the R&S FSW, the server can determine the cur­rent IP address for the connection using the permanent computer name.

1. Obtain the name of your DNS domain and the IP addresses of the DNS and

WINS servers on your network.

2. Press the SETUP key and then the "Network + Remote" softkey.

3. In the "Network" tab, select the "Open Dialog 'Network Configuration" button.

4. Double-tap the "Local Area Connection" icon.

5. In the "Local Area Connection Status" dialog box, select the "Properties" but-

ton.
The items used by the LAN connection are displayed.

6. Tap the entry named "Internet Protocol Version 4 (TCP/IPv4)" to highlight it.

8. On the "General" tab, select "Use the following DNS server addresses" and

enter your own DNS addresses.

For more information refer to the Windows operating system Help.

2.5.3 Using computer names

In a LAN that uses a DNS server (Domain Name System server), each PC or
instrument connected in the LAN can be accessed via an unambiguous computer
name instead of the IP address. The DNS server translates the host name to the
IP address. This is especially useful when a DHCP server is used, as a new IP
address may be assigned each time the instrument is restarted.

Each instrument is delivered with an assigned computer name, but this name can
be changed.

To change the computer name

1. Press the SETUP key and then the "Network + Remote" softkey.

The current "Computer Name" is displayed in the "Network" tab.

2.5.4 Changing the Windows Firewall Settings

A firewall protects an instrument by preventing unauthorized users from gaining
access to it through a network. Rohde & Schwarz highly recommends the use of
the firewall on your instrument. Rohde & Schwarz instruments are shipped with
the Windows firewall enabled and preconfigured in such a way that all ports and
connections for remote control are enabled. For more details on firewall configu­ration see the Rohde & Schwarz White Paper "Malware Protection" (available at

http://www2.rohde-schwarz.com/file_13784/1EF73_0E.pdf) and the Windows

Help system.

Note that changing firewall settings requires administrator rights.

5. If necessary, toggle the "Date and Time Format" between German (DE) and

US.

After you have made a change and closed the dialog box, the new date and
time is also adopted by the instrument.

2.7 Protecting Data Using the Secure User Mode

During normal operation, the R&S FSW uses a solid-state drive to store its oper­ating system, instrument firmware, instrument self-alignment data, and any user
data created during operation. If necessary, the solid-state drive can be removed
from the R&S FSW and locked in a secure place to protect any classified data it
may contain.

Redirecting storage to volatile memory

Alternatively, to avoid storing any sensitive data on the R&S FSW permanently,
the secure user mode was introduced (option R&S FSW-K33). In secure user
mode the instrument’s solid-state drive is write-protected so that no information
can be written to memory permanently. Data that the R&S FSW normally stores
on the solid-state drive is redirected to volatile memory instead, which remains
available only until the instrument is switched off. This data includes:

Windows 7 operating system files

●

Firmware shutdown files containing information on last instrument state

●

Self-alignment data

●

General instrument settings such as the IP address

●

Measurement settings

●

User data created during operation

●

● Any data created by other applications installed on the R&S FSW, for example

text editors (Notepad), the Clipboard, drawing tools etc.

Data that is stored in volatile memory can be accessed by the user just as in nor­mal operation; however, when the instrument’s power is removed, all data in this
memory is cleared. Thus, in secure user mode, the instrument always starts in a
defined, fixed state when switched on.

In order to store data such as measurement results permanently, it must be
stored to an external storage device, such as a memory stick.

31Getting Started 1312.9420.02 ─ 15

R&S®FSW

Protecting Data Using the Secure User Mode

Limited storage space

The volatile memory used to store data in secure user mode is restricted to
256 MB. Thus, a "Memory full" error may occur although the hard disk indi­cates that storage space is still available.

Storing required data permanently

Any data that is to be available for subsequent sessions with the R&S FSW, such
as predefined instrument settings, transducer factors or self-alignment data, must
be stored on the instrument permanently, prior to activating the secure user
mode.

Self-alignment data

Note that self-alignment data becomes invalid with time and due to temper­ature changes. Therefore, to achieve optimal accuracy, it may be preferable
to perform a new self-alignment at the start of each new session on the
R&S FSW.

Preparing for Use

Restricted operation

Due to the fact that permanent storage is not possible, the following functions are
not available in secure user mode:

Firmware update

●

Activating a new option key

●

Activating and deactivating secure user mode

Only a user with administrator rights can activate the secure user mode. Once
activated, a restart is required. The special user "SecureUser" is then logged on
to the R&S FSW automatically (using the automatic login function, see chap-

ter 2.2.3.1, "The Automatic Login Function", on page 20). While the secure user

mode is active, a message is displayed in the status bar at the bottom of the
screen.

R&S®FSW

Protecting Data Using the Secure User Mode

Secure Passwords

By default, the initial password for both the administrator account ("Instru­ment") and the "SecureUser" account is "894129". When the secure user
mode is activated the first time after installation, you are prompted to
change the passwords for all user accounts in order to improve system
security. Although it is possible to continue without changing the pass­words, it is strongly recommended that you do so.

You can change the password in Windows 7 for any user at any time via
"Start > Control Panel > User Accounts".

In order to deactivate the secure user mode, the "SecureUser" must log off and
the "Instrument" user (administrator) must log on.

Switching users when using the automatic login function

Preparing for Use

In the "Start" menu, select the arrow next to the "Shut down" button and
then "Log off".

The "Login" dialog box is displayed, in which you can enter the different
user account name and password.

The secure user mode setting and automatic login is automatically deactivated
when the "Instrument" user logs on. The "SecureUser" is no longer available.

The secure user mode setting is available in the general system configuration set­tings (SETUP key > "System Configuration" softkey > "Config" tab > "Secure
User Mode": "ON", see the R&S FSW User Manual).

Remote control

Initially after installation of the R&S FSW-K33 option, secure user mode must be
enabled manually once before remote control is possible. This is necessary to
prompt for a change of passwords.

(Analog) Baseband Input 50 Ω Connectors (optional)

The R&S FSW Analog Baseband Interface option (R&S FSW-B71) provides four
BASEBAND INPUT BNC connectors on the front panel of the instrument for ana­log I and Q signals.

47Getting Started 1312.9420.02 ─ 15

R&S®FSW

The upper BNC connectors BASEBAND INPUT I and BASEBAND INPUT Q are
used to input single-ended signals, the positive signal input for differential signals,
as well as input from active Rohde & Schwarz probes (R&S RT-ZSxx and differ­ential probes RT-ZDxx).

The lower BNC connectors Ī and Ǭ are used to input the negative signal for differ­ential signals.

Instrument Tour

Front Panel View

For complex signal input (I+jQ), always use two identical cables for the I
and Q connectors (same length, same type, same manufacturer). Other­wise, time delay or gain imbalance may occur between the different cables,
which cannot be calibrated.

All connectors have a fixed impedance of 50 Ω and may receive a maximum input
level of 4 Vpp each.

Risk of instrument damage

Do not overload the BASEBAND INPUT connectors. An input voltage of 4 V
must never be exceeded. Noncompliance will destroy the Analog Baseband
Interface components.

Input via the Analog Baseband Interface can be enabled in the I/Q Analyzer, the
Analog Demodulation application, or in one of the optional applications that proc­ess I/Q data (where available).

For more information on the Analog Baseband Interface (R&S FSW-B71) see the
R&S FSW I/Q Analyzer and I/Q Input User Manual.

3.1.14 TRIGGER INPUT / OUTPUT

The female TRIGGER INPUT connector for external trigger or gate input is used
to control the measurement by means of an external signal. The voltage levels
can range from 0.5 to 3.5 V. The default value is 1.4 V. The typical input impe­dance is 10 kΩ.

The female BNC TRIGGER INPUT / OUTPUT connector can be used to receive
a second external signal or to provide a signal to another device. The signal is
TTL compatible (0 V / 5 V). You can control the connector usage in the "Trigger"
settings (TRIG key).

The rear panel provides a third TRIGGER INPUT / OUTPUT connector, see

chapter 3.2.10, "TRIGGER 3 INPUT/ OUTPUT", on page 54.

3.1.15 EXT MIXER Connector (optional)

External mixers can be connected at the EXT MIXER LO OUT/IF IN and IF IN
female connectors to increase the available frequency range. This connector is
optional and only available with R&S FSW-B21.

If no external mixers are connected to the R&S FSW, cover the two front connec­tors LO OUT / IF IN and IF IN with the supplied SMA caps.

3.1.16

RF INPUT 50 Ω

A device under test (DUT) can be connected to the R&S FSW to provide RF input
which is then analyzed. The DUT is connected to the instrument's RF INPUT via
a cable equipped with an appropriate connector.

Risk of instrument damage

Do not overload the input. For maximum allowed values, see the data
sheet. For AC-coupling, a DC input voltage of 50 V must never be excee­ded. For DC-coupling, DC voltage must not be applied at the input. In both
cases, noncompliance will destroy the input mixers.

Bandwidth Extension 160 MHz/ 320 MHz/ 500 MHz with IF
WIDE OUTPUT Connector (R&S FSW-B160/-B320/-B500/­U160/-U320)

The signal analysis bandwidth of the R&S FSW can be extended by a hardware
option (R&S FSW-B160/-B320/-B500 or R&S FSW-U160/-U320). The bandwidth
extension allows for a linear bandwidth up to a maximum of 160 MHz (with option
B160/U160), 320 MHz (with option B320/U320), or 500 MHz (with option B500),
with an output sample rate of up to 10 GHz. While the extension can be activated
or deactivated manually in the R&S FSW base unit (I/Q Analyzer application), it is
activated automatically in some applications that also support I/Q data analysis.
See the application-specific documentation for details.

The bandwidth extension option R&S FSW-B320/-U320 requires a refer­ence board revision 3.14 or higher.

The bandwidth extension option R&S FSW-B500 requires a reference
board (1312.8075.06) revision 4.06 or higher and a motherboard

1313.4180.02 or 1313.7698.02.

Together with the bandwidth extension an additional IF output connector is provi­ded (IF WIDE OUTPUT). As opposed to the default IF/VIDEO/DEMOD OUTPUT
connector, the IF output frequency of the optional connector cannot be defined
manually, but is determined automatically depending on the center frequency. For
details on the used frequencies see the data sheet. The IF WIDE OUTPUT con­nector is used automatically when the bandwidth extension is activated (i.e. for
bandwidths > 80 MHz).

IF OUTPUT (2 GHz)

The female SMA connector is only available for instrument models
R&S FSW43/50/67 and can be used to provide intermediate frequency (IF) output
of approximately 2 GHz at a frequency of 2 GHz.

Output is activated in the software (INPUT/OUTPUT key).

For details see the User Manual.

3.2.9

Digital Baseband Interface (R&S FSW-B17) and R&S EX­IQ-BOX

The R&S FSW Digital Baseband Interface option (R&S FSW-B17) provides an
online digital I/Q data interface on the rear panel of the instrument for input and
output. The digital input and output can be enabled in the base unit or in one of
the applications (where available).

Optionally, an R&S EX-IQ-BOX can be connected to the Digital Baseband Inter­face to convert signal properties and the transmission protocol of the R&S FSW
into user-defined or standardized signal formats and vice versa.

Since the Digital I/Q input and the Analog Baseband input use the same
digital signal path, both cannot be used simultaneously. When one is activa­ted, established connections for the other are disconnected. When the sec­ond input is deactivated, connections to the first are re-established. This
may cause a short delay in data transfer after switching the input source.

3.2.10 TRIGGER 3 INPUT/ OUTPUT

The additional female BNC TRIGGER INPUT / OUTPUT connector can be used
to receive a third external signal or to provide a signal to another device. The sig­nal is TTL compatible (0 V / 5 V). You can control the connector usage in the
"Trigger" settings (TRIG key).

3.2.11 SYNC TRIGGER OUTPUT/INPUT

The SYNC TRIGGER OUTPUT/INPUT connectors allow you to synchronize sev­eral devices (e.g. two R&S FSWs) with respect to the trigger signal, but also the
reference frequency. A 100 MHz signal can be output as a trigger or reference
signal to another device, and an external trigger or reference signal can be
received at the input connector by the R&S FSW.

Displaying a Spectrogram

4.2 Displaying a Spectrogram

In addition to the standard "level versus frequency" spectrum display, the
R&S FSW also provides a spectrogram display of the measured data. A spectro­gram shows how the spectral density of a signal varies over time. The x-axis
shows the frequency, the y-axis shows the time. A third dimension, the power
level, is indicated by different colors. Thus you can see how the strength of the
signal varies over time for different frequencies.

1. Tap the "Overview" softkey to display the general configuration dialog box.

2. Tap the "Display Config" button.

The SmartGrid mode is activated, and the evaluation bar with the available
evaluation methods is displayed.

3.

Drag the "Spectrogram" icon from the evaluation bar to the diagram area. The
blue area indicates that the new diagram would replace the previous spectrum
display. Since we do not want to replace the spectrum, drag the icon to the
lower half of the display to add an additional window instead.

4. Close the SmartGrid mode by tapping the "Close" icon at the top right corner

of the toolbar.

You see the spectrogram compared to the standard spectrum display. Since
the calibration signal does not change over time, the color of the frequency
levels does not change over time, i.e. vertically. The legend at the top of the
spectrogram window describes the power levels the colors represent.

4.3 Activating Additional Measurement Channels

The R&S FSW features multiple measurement channels, i.e. you can define sev­eral measurement configurations in parallel and then switch between the chan­nels automatically to perform the measurements sequentially. We will demon­strate this feature by activating additional measurement channels for a different
frequency range, a zero span measurement, and an I/Q analysis.

Understanding the Display Information

5.1.1 Channel Bar

Using the R&S FSW you can handle several different measurement tasks (chan­nels) at the same time (although they can only be performed asynchronously).
For each channel, a separate tab is displayed on the screen. In order to switch
from one channel display to another, simply select the corresponding tab.

Alternatively, if many tabs are displayed, select the tab selection list icon at the
right end of the channel bar and select the channel you want to switch to from the
list.

MultiView tab

An additional tab labelled "MultiView" provides an overview of all active channels
at a glance. In the "MultiView" tab, each individual window contains its own chan­nel bar with an additional button. Tap this button to switch to the corresponding
channel display quickly.

Understanding the Display Information

Icons in the channel bar

The icon on the tab label indicates that the displayed trace no longer matches
the current instrument settings. This may be the case, for example, if a trace is
frozen and the instrument settings are changed. As soon as a new measurement
is performed, the icon disappears.

The icon indicates that an error or warning is available for that measurement
channel. This is particularly useful if the MultiView tab is displayed.

An orange "IQ" (in MSRA mode only) indicates that the results displayed in the
MSRA application(s) no longer match the data captured by the MSRA Master.
The "IQ" disappears after the results in the application(s) are refreshed.

The icon indicates the currently active channel during an automatic measure­ment sequence (Sequencer functionality).

Channel-specific settings

Beneath the channel name, information on channel-specific settings for the mea­surement are displayed in the channel bar. Channel information varies depend­ing on the active application.

In the Spectrum application, the R&S FSW shows the following settings:

5.5 Displaying Results

The R&S FSW provides several instrument applications for different analysis
tasks and different types of signals, e.g. 3G FDD, I/Q analysis or basic spectrum
analysis. For each application, a new measurement channel is created and dis­played in a separate tab on the screen.

R&S®FSW

Operating the Instrument

Displaying Results

The results of a measurement channel can be evaluated in many different ways,
both graphically and numerically. For each evaluation method the results are dis­played in a separate window in the tab.

The R&S FSW allows you to configure the display to suit your specific require­ments and optimize analysis.

5.5.1 Activating and Deactivating Channels

When you activate an application, a new measurement channel is created which
determines the measurement settings for that application. The same application
can be activated with different measurement settings by creating several chan­nels for the same application. Whenever you switch channels, the corresponding
measurement settings are restored. Each channel is displayed in a separate tab
on the screen.

An additional tab ("MultiView") provides an overview of all currently active chan­nels at once.

Only one measurement can be performed at any time, namely the one in the cur­rently active channel. However, in order to perform the configured measurements
consecutively, a Sequencer function is provided.

that channel are deleted.

5.5.2 Laying out the Result Display with the SmartGrid

Measurement results can be evaluated in many different ways, for example
graphically, as summary tables, statistical evaluations etc. Each type of evalua­tion is displayed in a separate window in the channel tab. Up to 16 individual win­dows can be displayed per measurement channel (i.e. per tab). To arrange the
diagrams and tables on the screen, the Rohde & Schwarz SmartGrid function
helps you find the target position simply and quickly.

(For details on evaluation methods see the User Manual.)

Principally, the layout of the windows on the screen is based on an underlying
grid, the SmartGrid. However, the SmartGrid is dynamic and flexible, allowing for
many different layout possibilities. The SmartGrid functionality provides the fol­lowing basic features:

Windows can be arranged in columns or in rows, or in a combination of both.

●

Windows can be arranged in up to four rows and four columns.

●

R&S®FSW

Operating the Instrument

Displaying Results

Windows are moved simply by dragging them to a new position on the screen,

●

possibly changing the layout of the other windows, as well.
All evaluation methods available for the currently selected measurement are

●

displayed as icons in the evaluation bar. If the evaluation bar contains more
icons than can be displayed at once on the screen, it can be scrolled verti­cally. The same evaluation method can be displayed in multiple windows
simultaneously.

New windows are added by dragging an evaluation icon from the evaluation

●

bar to the screen. The position of each new window depends on where you
drop the evaluation icon in relation to the existing windows.

All display configuration actions are only possible in SmartGrid mode. When

●

SmartGrid mode is activated, the evaluation bar replaces the current softkey
menu display. When the SmartGrid mode is deactivated again, the previous
softkey menu display is restored.

5.5.2.1 Background Information: The SmartGrid Principle

SmartGrid display

During any positioning action, the underlying SmartGrid is displayed. Different
colors and frames indicate the possible new positions. The position in the Smart­Grid where you drop the window determines its position on the screen.

Fig. 5-1: Moving a window in SmartGrid mode

The brown area indicates the possible "drop area" for the window, i.e. the area in
which the window can be placed. A blue area indicates the (approximate) layout
of the window as it would be if the icon were dropped at the current position. The
frames indicate the possible destinations of the new window with respect to the
existing windows: above/below, right/left or replacement (as illustrated in fig-

ure 5-2). If an existing window would be replaced, the drop area is highlighted in a

darker color shade.

Positioning the window

The screen can be divided into up to four rows. Each row can be split into up to
four columns, where each row can have a different number of columns. However,
rows always span the entire width of the screen and may not be interrupted by a
column. A single row is available as the drop area for the window in the Smart­Grid. The row can be split into columns, or a new row can be inserted above or
below the existing row (if the maximum of 4 has not yet been reached).

Once the evaluation icon has been dropped, icons in each window provide delete
and move functions.

The "Move" icon allows you to move the position of the window,

possibly changing the size and position of the other displayed win-

dows.

The "Delete" icon allows you to close the window, enlarging the

display of the remaining windows.

5.5.2.2 How to Activate SmartGrid Mode

All display configuration actions are only possible in SmartGrid mode. In Smart­Grid mode the evaluation bar replaces the current softkey menu display. When
the SmartGrid mode is deactivated again, the previous softkey menu display is
restored.

► To activate SmartGrid mode, do one of the following:

●

Select the "SmartGrid" icon from the toolbar.

● Select the "Display Config" button in the configuration "Overview".

● Select the "Display Config" softkey from the MEAS CONFIG menu.

The SmartGrid functions and the evaluation bar are displayed.

5.5.2.3 How to Add a New Result Window

Each type of evaluation is displayed in a separate window. Up to 16 individual
windows can be displayed per measurement channel (i.e. per tab).

1. Activate SmartGrid mode.

All evaluation methods available for the currently selected measurement are
displayed as icons in the evaluation bar.

2. Select the icon for the required evaluation method from the evaluation bar.

If the evaluation bar contains more icons than can be displayed at once on the
screen, it can be scrolled vertically. Touch the evaluation bar between the
icons and move it up or down until the required icon appears.

3. Drag the required icon from the evaluation bar to the SmartGrid, which is dis-

played in the diagram area, and drop it at the required position. (See chap-

ter 5.5.2.5, "How to Arrange the Result Windows", on page 98 for more

information on positioning the window).

The splitters are not available in SmartGrid mode.

► To change the size of two neighboring windows, drag the splitter between the

windows in either direction.

5.5.4 Switching Between a Split and Maximized Window Dis-

play

To get an overview of the results, displaying several windows at the same time
may be helpful. However, the individual windows may become rather small. In
this case it is useful to maximize an individual window to the entire screen tempo­rarily in order to analyze the results in more detail.

To switch between a split and a maximized display without having to close and
re-open windows, press the SPLIT/MAXIMIZE key on the front panel. In maxi­mized display, the currently focused window is maximized. In split display, all
active windows are displayed.
