If necessary, also ground the product using the grounding terminal
The maximum power consumption and the typical power consumption of the individual
analyzer models are listed in the data sheet.
The R&S ZNBT is protected by a fuse located below the AC power switch. For fuse
replacement, see the corresponding section in the maintenance chapter of the user
manual. There is no such fuse on the R&S ZNB.
Risk of data loss due to voltage dips
For a R&S ZNBT40 with 24 ports, a voltage dip with a duration of 18 ms or higher can
cause a spontaneous reboot of the instrument. I.e. in its maximum configuration, the
R&S ZNBT40 does not fully comply with standard EN 61326-2-1, chapter 6.4.101.
The reboot time is approximately 90 s. Note that the instrument settings after a spontaneous reboot are those that were active before the most recent regular shutdown or
reboot. Settings that have been changed since then are lost. To preserve changes in
the active setup, you must perform a regular shutdown or reboot.

ment on and off", on page 17.
The analyzer is equipped with a Windows® operating system which has been configured according to the instrument's features and needs. Changes in the system configuration can be necessary to:
●
Establish a LAN connection
●
Customize the properties of the external accessories connected to the analyzer
●
Call up additional software tools
Modifications of the operating system
The operating system is adapted to the network analyzer. To avoid impairment of
instrument functions, only change the settings described in this manual. Existing software must be modified only with update software released by Rohde & Schwarz. Likewise, only programs authorized by Rohde & Schwarz for use on the instrument must
be executed.
All necessary settings can be accessed from the Windows "Start" menu, in particular
from the "Control Panel". To open the "Start" menu, press the Windows key in the toolbar or on an external keyboard.
User accounts and password protection
The analyzer uses a user name and password as credentials for remote access. Two
user accounts with different levels of access are available on the instrument:
●
"instrument" is the default account with standard rights to change system settings.
Use this account for normal operation of the analyzer.
●
"Admin" is the account for administering the operating system. This account is
required, for instance, if you wish to install programs on the analyzer.
[For instruments running Windows 7, this account is named "Administrator".]
In the factory configuration, "894129" is preset as a password for both users. To protect
the analyzer from unauthorized access, it is recommended to change the preset passwords.
To switch from one user account to another, log off from Windows and then log on
again. The "switch user" functionality is disabled on the R&S ZNB/ZNBT.

associated update server. Update instruments using Windows regularly, especially
instruments that connect to a network.
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 Windows-based 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:

Remote operation in a LAN
Printer configuration
Use the "Printer Setup" dialog of the firmware (System – [Print] > "Print...") or the Windows® printer management to configure the printer properties and printing preferences.
A LAN cable can be connected to the LAN connector on the rear panel of the analyzer.
To establish a LAN connection, proceed as follows:
1. Refer to Chapter 3.12.1, "Assigning an IP address", on page 25.
2. Connect a CAT6 or CAT7 LAN cable to the LAN port.
The LAN port of the analyzer is an auto-crossover Ethernet port. You can connect it to
a network, but you can also set up a direct connection to a computer or another instrument. For both connection types, you can use either crossover or straight through
(patch) cables.
The IP address information is shown in the System – [Setup] > "Remote Settings" softtool tab. For the R&S ZNBT, it is also shown on the Mini display.
3.11.6 Connecting a USB cable for remote control
Instruments equipped with the latest controller board can also be remote controlled via
USB. To prepare for remote control operation, connect a suitable USB 2.0 or 3.0 cable
to the type B "USB Device" port on the rear panel of the instrument. With direct connection to a master device, a connecting cable A-B (plug type A onto plug type B) must
be used.
For more information, refer to the Remote Control chapter of your analyzer's help system or user manual.
3.12 Remote operation in a LAN
A LAN connection is used to integrate the analyzer into a home/company network.
LAN connectivity offers several applications, e.g.:
●
Transfer data between a controller and the analyzer, e.g. to run a remote control
program.
●
Control the measurement from a remote computer using Remote Desktop or a similar application.
●
Use external network devices (e.g. printers).
The analyzer uses a user name and password as credentials for remote access; see
note on "User accounts and password protection" on page 19 for details. To protect the
analyzer from unauthorized access, it is recommended to change the factory setting.

3.12.1 Assigning an IP address
Preparing for use
Remote operation in a LAN
Depending on the network capacities, the TCP/IP address information for the analyzer
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 analyzer is set to use alternate
TCP/IP configuration, the addresses must be set manually.
By default, the analyzer is configured to use dynamic TCP/IP configuration and obtain
all address information automatically. Hence it is safe to establish a physical connection to the LAN without any previous analyzer configuration.
Manual TCP/IP configuration
If your network does not support DHCP, or if you choose to disable dynamic TCP/IP
configuration, you must assign valid address information before you connect the analyzer to the LAN. Contact your network administrator to obtain a valid IP address,
because connection errors can affect the entire network.
Admin account
You need administrator rights to change the TCP/IP configuration. See note on "User
accounts and password protection" on page 19 for details.
The R&S ZNBT provides a miniature display in the upper right-hand corner of the front
panel indicating the current IP address of the instrument. See Mini display.
To enter the TCP/IP address information manually
1. Obtain the IP address and subnet mask for the analyzer and the IP address for the
local default gateway from your network administrator. If necessary, also obtain the
name of your DNS domain and the IP addresses of the DNS and WINS servers on
your network.
2. For the R&S ZNBT, connect an external monitor, keyboard and mouse.
3. Press the Windows key in the System keypad (R&S ZNB only) or on an external
keyboard to access Windows®.
4. Open the "Control Panel" > "Network and Sharing Center" > "Change adapter settings" dialog and right-click the local connection.
Windows 7: open the "Control Panel" > "Network and Internet" > "Network and
Sharing Center" > "Local Area Connection Status" dialog.
5. Select "Properties" and confirm the user account control message, depending on
your current user account.
