R&S®ESW
Windows Operating System
Tested software
The drivers and programs used on the instrument under Microsoft Windows are adapted to the instrument. Only install update software released by Rohde & Schwarz to modify existing instrument software.
You can install additional software on the instrument; however, additional soft­ware can impair instrument function. Thus, run only programs that Rohde & Schwarz has tested for compatibility with the instrument software.
The following program packages have been tested:
Symantec Endpoint Security – virus-protection software
FileShredder - for reliable deletion of files on the hard disk
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.
Preparing for Use
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.
Note that changing firewall settings requires administrator rights.
Virus protection
Take appropriate steps to protect your instruments from infection. Use strong fire­wall settings and scan any removable storage device used with a Rohde & Schwarz instrument regularly. It is also recommended that you install anti-virus software on the instrument. Rohde & Schwarz does NOT recommend running anti-virus software in the background ("on-access" mode) on Windows­based instruments, due to potentially degrading instrument performance. How­ever, Rohde & Schwarz does recommend running it during non-critical hours.
For details and recommendations, see the following Rohde & Schwarz white paper:

Considerations for Test Setup
Preparing for Use

4.13 Performing a Self-Alignment

When strong temperature changes occur in the environment of the R&S ESW, or after updating the firmware, you have to perform a self-alignment to align the data to a reference source.
During self-alignment, do not connect a signal to the RF input connector. Running a self-alignment with a signal connected to the RF input can lead to false mea­surement results.
Performing a self-alignment
Before performing this functional test, make sure that the instrument has reached its operating temperature (for details, refer to the data sheet).
A message in the status bar ( "Instrument warming up..." ) indicates that the oper­ating temperature has not yet been reached.
Depending on the installation settings, an automatic self-alignment is performed each time the instrument is switched on. A dialog is displayed indicating how much warm-up time is still required before self-alignment can be performed.
1. Press the [Setup] key.
2. Press the "Alignment" softkey.
3. Select the "Start Self Alignment" button in the "Alignment" dialog box.
Once the system correction values have been calculated successfully, a mes­sage is displayed.
To display the alignment results again later

4.14 Considerations for Test Setup

Cable selection and electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
33Getting Started 1328.4922.02 ─ 09
R&S®ESW
Protecting Data Using the Secure User Mode
To suppress electromagnetic radiation during operation:
Use high-quality shielded cables, for example, double-shielded RF and LAN cables.
Always terminate open cable ends.
Ensure that connected external devices comply with EMC regulations.
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a DUT.
NOTICE! Risk of electrostatic discharge. Electrostatic discharge can damage
the electronic components of the product and the device under test (DUT). Ground yourself to prevent electrostatic discharge damage: a) Use a wrist strap and cord to connect yourself to ground.
b) Use a conductive floor mat and heel strap combination.
Preparing for Use
Signal input and output levels
Information on signal levels is provided in the data sheet. Keep the signal levels within the specified ranges to avoid damage to the R&S ESW and connected devices.

4.15 Protecting Data Using the Secure User Mode

During normal operation, the R&S ESW uses a solid-state drive to store its oper­ating system, instrument firmware, instrument self-alignment data, and any user data created during operation.
Redirecting storage to volatile memory
Alternatively, to avoid storing any sensitive data on the R&S ESW permanently, the secure user mode was introduced (option R&S ESW-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 ESW 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 operating system files
34Getting Started 1328.4922.02 ─ 09
R&S®ESW
Protecting Data Using the Secure User Mode
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 ESW, for exam­ple, text editors (Notepad), the clipboard, or drawing tools.
Users can access data that is stored in volatile memory just as in normal opera­tion. However, when the instrument’s power is switched off, all data in this mem­ory is cleared. Thus, in secure user mode, the instrument always starts in a defined, fixed state when switched on.
To store data such as measurement results permanently, it must be stored to an external storage device, such as a memory stick.
Preparing for Use
Limited storage space
The volatile memory used to store data in secure user mode is restricted to 256 MB. Thus, a "Memory full" error can 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 ESW must be stored on the instrument permanently, before activating the secure user mode. This includes predefined instrument settings, transducer factors and self-align­ment data.
Self-alignment data
Note that self-alignment data becomes invalid with time and due to tempera­ture changes. Therefore, to achieve optimal accuracy, it can be preferable to perform a new self-alignment at the start of each new session on the R&S ESW.
Restricted operation
Since permanent storage is not possible, the following functions are not available in secure user mode:
Firmware update
35Getting Started 1328.4922.02 ─ 09
R&S®ESW
Protecting Data Using the Secure User Mode
Activating a new option key
Furthermore, since the "SecureUser" used in secure user mode does not have administrator rights, administrative tasks such as LAN configuration and some general instrument settings are not available. Refer to the description of the basic instrument setup ([SETUP] menu) to find out which functions are affected.
Activating and deactivating secure user mode
Only a user with administrator rights can activate (and deactivate) the secure user mode. Once activated, a restart is required. The special user "SecureUser" is then logged on to the R&S ESW automatically using the auto-login function. While the secure user mode is active, a message is displayed in the status bar at the bottom of the screen.
Secure passwords
Preparing for Use
By default, the initial password for both the administrator account 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 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 Microsoft Windows for any user at any time via:
"Start > Settings > Account > SignIn Options > Password > Change"
To deactivate the secure user mode, the "SecureUser" must log off and a user with administrator rights must log on.
Switching users when using the auto-login function
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 auto-login is automatically deactivated when another user logs on. The "SecureUser" is no longer available.
For users with administrator rights, the secure user mode setting is available in the general system configuration settings ([Setup] key > "System Configuration"

The first RF Input supports a frequency range from 2 Hz to f tion range from 0 dB to 75 dB. The second RF Input supports a frequency range
from 2 Hz to 1 GHz and an attenuation range from 10 dB to 75 dB. Attenuation
and an attenua-
max
42Getting Started 1328.4922.02 ─ 09
R&S®ESW
levels smaller than 10 dB at RF Input 2 are only possible when the pulse limiter is not active (refer to the User Manual for more information).
Risk of instrument damage
Do not overload the RF 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.
When measuring unknown signals, do not use a 0 dB attenuation level. Otherwise, the input mixer may be damaged or destroyed.
When measuring unknown signals on the second RF input, turn on the pulse limiter feature. Otherwise, the input mixer may be damaged or destroyed in case of high power signals.

Touch gestures in diagrams change measurement settings
When you change the display using touch gestures, the corresponding mea­surement settings are adapted. This is different to selecting an area on the screen in zoom mode, where merely the resolution of the displayed trace points is changed temporarily (graphical zoom).
You can prevent the firmware from changing specific settings using the options in the context menu for the measurement zoom icon. By default, the reference level is locked and thus not changed automatically due to touch gestures.

6.6 Displaying Results

The R&S ESW provides several instrument applications for different analysis tasks and different types of signals, for example the Receiver application, the Spectrum application or the I/Q Analyzer. For each application, a new measure­ment channel is created and displayed in a separate tab on the screen.
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 ESW allows you to configure the display to suit your specific require­ments and optimize analysis.

6.6.1 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.

6.6.2 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 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.
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.

6.6.2.1 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.
Figure 6-5: 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 6-6). 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 windows.
The "Delete" icon allows you to close the window, enlarging the display of the remaining windows.
6.6.2.2 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
80Getting Started 1328.4922.02 ─ 09

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.
6.6.4 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 re­open 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.
