2.1.3 Setting Up a Network (LAN) Connection

Getting Started
Preparing for Use
Connecting a mouse
A mouse is detected automatically when it is connected.
The R&S SMB100B 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, the interface can be used, for example:
●
To transfer data between a controller and the instrument, for example to run a remote control program. See Chapter 10, "Network Operation and Remote Control", on page 250.
●
To access or operate the instrument from a remote computer using the Ultr@VNC program (or a similar tool, like another VNC client or any Web browser supporting Java).
●
To transfer data from a remote computer and back, for example using network fold­ers.
●
To use power sensors with netwok capability, e.g. the R&S NRP LAN power sen­sors.
This section describes how to configure the LAN interface.
Accessing operating system
No access to the operating system is required for normal operation. All necessary system settings can be made in the "Setup" dialog.
2.1.3.1 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
●
A dedicated network connection (Point-to-point connection) between the instru­ment and a single computer
For addressing, both the instrument and the computer reqiure an IP address. The address information is usually assigned to the devices automatically, depending on the network capabilities.
If the IP address is not assigned automatically, see Chapter 2.1.3.3, "Assigning the IP
Address", on page 28 for information on how to assign the address manually.
26User Manual 1178.3711.02 ─ 03
R&S®SMB100B
Getting Started
Preparing for Use
To set up a network (LAN) connection
Risk of network failure
Consult your network administrator before performing the following tasks:
●
Connecting the instrument to the network
●
Configuring the network
●
Changing IP addresses
Errors can affect the entire network.
► Connect the instrument to the network or to a single PC.
If the instrument is connected to the LAN, the operating system automatically detects the network connection and activates the required drivers. By default, the instrument is configured to use DHCP (dynamic host configuration protocol) configuration and to obtain the whole address information automatically.
When connected, the R&S SMB100B displays the address information on the screen.
Risk of network connection failure
Network cables and cable connectors of poor quality, or failures in the autonegotiation process, can cause network connection failures.
If the network connection to the instrument fails, check the network infrastructure and contact your network administrator.
For details, see section "Troubleshooting and Error Messages".
2.1.3.2 Using Computer Names (Hostnames)
In a LAN that uses a DNS server, each PC or instrument connected in the LAN can be accessed via an unambiguous computer name (hostname) instead of the IP address. The DNS server translates the hostname to the IP address. It is especially useful when a DHCP server is used, as a new IP address can be assigned each time the instru­ment is restarted.
Each instrument is delivered with an assigned computer name, that remains perma­nent as long as it is not explicitly changed.
27User Manual 1178.3711.02 ─ 03
R&S®SMB100B
Getting Started
Preparing for Use
The default computer name follows the syntax <INST>-<Serial Number> (previous syntax: rs<inst><Serial Number>), where:
●
<INST> is the short name of your instrument, as stated on the front panel.
●
<Serial Number> is the individual serial number of the instrument. You can find the serial number at the rear panel of instrument. It is the third part of the device ID printed on the barcode sticker .
Example:
The default hostname of an R&S SMB100B with a serial number 102030 is SMB100B-102030.
To query and change a computer name
1. Press the [Setup] key.
2. Select "Remote Access > Network". The computer name is displayed under "Hostname".
3. Press the [Setup] key.
4. Select "Security > Protection".
5. Enable the "Protection Level 1". The default password is 123456.
The parameter "Hostname" in the "Network" tab is now enabled for configuration.
6. Change the "Hostname".
2.1.3.3 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 DHCP (dynamic host configuration protocol), the address information is assigned automatically.
●
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.
Since the dynamic TCP/IP configuration assigns the address information automatically, it is safe to establish a physical connection to the LAN without any previous instrument configuration.
