4.13 Default Settings
Preparing for Use
Default Settings
When the instrument is switched on, it is not the preset state that is active, but rather
the instrument state that was set before the instrument was switched off. It is also recomended that you use the [PRESET] key to return the instrument to its defined preset
state every time a new configuration is required or the current setup is not anymore relevant.
The R&S SMB offers a two-stage preset concept:
●
Preset the instrument to a predefined state
The [PRESET] key calls up a defined instrument setup. All parameters and switching states are preset (also those of inactive operating modes). The default instrument settings provide a reproducible initial basis for all other settings. However,
functions that concern the integration of the instrument into a measurement setup
are not changed, e.g. GPIB bus address or reference oscillator source settings.
●
Preset the instrument to its factory settings
The instrument can also be forced to load its default factory settings. To access the
corresponding dialog box, press the [SETUP] key and select the "Factory Preset".
For more information and an overview of the settings affected by the factory preset
function, see section "Factory Preset" in the Operating Manual.
Overview of the Most Important Preset States

User-defined instrument states can be stored and called up in the "File" dialog.
The instrument uses an embedded Linux operating system, optimally adapted to the
instrument.
Accessing the operating system
No access to the operating system is required for normal operation.
All necessary system settings can be made in the "Setup" dialog.
4.15 Setting Up a Network (LAN) Connection
The R&S SMB 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 Linux firewall configuration is adapted accordingly,
the interface can be used, for example:
●
To transfer data between a controller and the instrument, e.g. in order to run a
remote control program.
●
To access or control the measurement from a remote computer using the R&S
VISA or Ultr@VNC programs (or similar tools, like another VNC client or any Web
browser supporting Java)
●
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 4.7, "Connecting to LAN", on page 18
●
Chapter 4.15.1, "Assigning the IP Address", on page 24
4.15.1 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.
24Quick Start Guide 1407.0812.62 ─ 20
R&S®SMB100A
Preparing for Use
Setting Up a Network (LAN) Connection
●
If the network does not support DHCP, the instrument tries to obtain the IP address
via Zeroconf (APIPA) protocol. If this attempt does not succeed or if the instrument
is set to use alternate 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 and select the "Network Settings" dialog.
2. Set the "Address Mode" to Static.
3. Select the "IP Address" and enter the IP address, for example 192.168.0.1..
The IP address consists of four number blocks separated by dots. Every block contains 3 numbers in maximum.
4. Select the "Subnet Mask" and enter the subnet mask, for example 255.255.255.0.
The subnet mask consists of four number blocks separated by dots. Every block
contains 3 numbers in maximum.
Use computer names to identify the instrument
In networks using a DHCP server, it is recommended that you address the instrument
by its unambiguous computer name, see Chapter 4.15.2, "Using Computer Names",
on page 26.
A computer name (hostname) is an unique dedicated identification of the instrument,
that remains permanent as long as it is not explicitly changed. Hence, you can address
an instrument by the same identification (computer name), irrespectively if a network or
a point-to-point connection is used.
To assign the IP address manually on the remote computer
► Obtain the necessary information from your network administrator. If you use more
than one LAN connector, you need separate address information for each connector.
For information on how to perform the configurations, refer to the documentation of
the operating system the remote computer uses.

4.15.2 Using Computer Names
Preparing for Use
Remote Access via an External Controller
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.
The default instrument name is a non-case-sensitive string that follows the syntax
rs<instrument><serial number>.
The serial number can be found on the rear panel of the instrument. It is the third part
of the device ID printed on the bar code sticker:
Querying and changing a computer name
1. Press the "Setup" key and select "Network Settings".
The computer name is displayed under "Hostname".
2. Press the "Setup" key, select "Protection" and enable the "Protection Level 1".
The default password is 123456.
The parameter "Hostname" in the "Network Settings" dialog is now enabled for
configuration.
3. Change the "Hostname".
4.16 Remote Access via an External Controller
The R&S SMB can be remote accessed from a remote computer (external controller)
via a network link. This allows convenient operation of the instrument from the desktop
although the instrument is integrated in a rack somewhere else.
For an overview of the instrument's operating concept and the different ways to control
and operate the instrument, see Chapter 7, "System Overview", on page 58.
There are different ways to establish a remote access connection to the signal generator but all of them require an established LAN connection between the instrument and
the remote computer. The simplest way to remote access the instrument is to use a
