Connecting an external monitor
Screen resolution and format
The touchscreen of the R&S ZNL is calibrated for a 16:10 format. If you connect a monitor or projector using a different format (e.g. 4:3), the calibration
is not correct and the screen does not react to your touch actions properly.
The touchscreen has a screen resolution of 1280x800 pixels. Usually, the
display of the external monitor is a duplicate of the instrument's monitor.
If you configure the external monitor to be used as the only display in the
Windows configuration dialog box ("Show only on 2"), the maximum screen
resolution of the monitor is used. In this case, you can maximize the
R&S ZNL application window and see even more details. You cannot
change the monitor's screen resolution via the standard Windows configuration dialog box.
The R&S ZNL supports a minimum resolution of 1280x768 pixels.
Preparing for use
1. Connect the external monitor to the R&S ZNL.
2. Press the [Setup] key.
3. Press the "Display" softkey.
4. Select the "Configure Monitor" tab in the "Display" dialog box.

5. If necessary, change the screen resolution. Consider the information in the
note above.
6. Select the instrument for display:
● "Display 1" : internal monitor only
● "Display 2" : external monitor only
● "Duplicate" : both internal and external monitor
7. Tap "Apply" to try out the settings before they are accepted permanently, then
you can easily return to the previous settings, if necessary.
8. Select "OK" if the settings are suitable.
Fixing a wrong touchscreen mapping
For instruments that are equipped with a system image version < 0.8, the touchscreen function is erroneously mapped to the external monitor by default. This
mismatch is particularly inconvenient in extended display mode, where touch gestures on the instrument screen actually operate on the external screen. In duplicate monitor mode, touch screen operation also malfunctions if the resolutions of
the internal and external display do not match.
Preparing for use
To fix the mapping between touchscreen and display, connect an external monitor
to the R&S ZNL and proceed as follows:
1. Select [Setup] > "Display" > "Configure Monitor" > "Display Switch" to bring up
the Windows 10 "PROJECT" notification window.
Or press [Win]+[P] on a connected keyboard.
2. Select "Extend".
3. In the Windows task bar, search for "tablet" and select "Tablet PC Settings"
4. In the "Tablet PC Settings" dialog, select "Setup…". Enter the administrator
password to proceed.
Observe the message "Touch this screen to identify it as the touchscreen" on
the internal touch screen.
5. Tap on the internal touch screen.
6. Press [ENTER].
Observe the message "Touch this screen to identify it as the touchscreen" on
the external screen.
7. If the external monitor is also a touchscreen, tap on it.

Preparing for use
3.10 Windows operating system
The instrument contains the Windows 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 a keyboard or a printer are installed
or if the network configuration does not comply with the default settings. After the
R&S ZNL is started, the operating system boots and the instrument firmware is
started automatically.
Tested software
The drivers and programs used on the instrument under 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. They are released through the Microsoft Update
website and associated update server. Update instruments using Windows regularly, especially instruments that connect to a network.

Windows operating system
Firewall settings
A firewall protects an instrument by preventing unauthorized users from gaining
access to it through a network. Rohde & Schwarz highly recommends using the
firewall on your instrument. Rohde & Schwarz instruments are shipped with the
Windows firewall enabled. 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.
Preparing for use
For details and recommendations, see the following Rohde & Schwarz white
paper:

Preparing for use
Logging on
3.11 Logging on
Windows requires that users identify themselves by entering a user name and
password in a login window. By default, the R&S ZNL provides two user
accounts:
●
"Instrument" : a standard user account with limited access
●
"Admin" or "Administrator" (depends on firmware image): an administrator
account with unrestricted access to the computer/domain
Some administrative tasks require administrator rights (e.g. the configuration of a
LAN network). Refer to the description of the basic instrument Setup ([Setup]
menu) to find out which functions are affected.
Passwords
For all default user accounts, the initial password is 894129. Note that this password is very weak, and we strongly recommend that you change the password for
both users after initial login. An administrator can change the password in Windows for any user at any time via "Start > Settings > Account > SignIn Options >
Password > Change".
Auto-login
When shipped, the instrument automatically logs on the default "Instrument" user
to Windows using the default password. This function is active until an administrator explicitly deactivates it or changes the password.
Changing the password and use of auto-login function
Note that when you change the default password, the default auto-login
function no longer works!
In this case, you must enter the new password manually to log on.
