1.1 Key Features
Preface
Documentation Overview
The R&S SGS is a signal generator intended either for the generation of IQ-modulated
signals or as a pure local oscillator (LO) source.
Optimized for use in automated test equipment (ATE), the instrument offers fast settling
times in an exceptionally small form factor and low power consumption. The R&S SGS
can be equipped optionally with an active electronic step attenuator, a high stability reference oscillator and LO connectors for coupling multiple generators to a common LO
source.
The key features of the R&S SGS include the following:
●
Compact size and low power consumption
●
Remote connection via PCI Express, minimizing the setup time
Alternatively, LAN or USB connections available
●
Coherent LO input and output connectors, also usable as MIMO input/output and
phase coherent I/Q demodulation
●
Broadband analog input for vector modulation (I, Q)
●
Linux operating system
●
Graphical user interface R&S SGMA-GUI to set up and control one or more
R&S SGS instruments simultaneously from one remote computer, available for
Windows and Linux systems

2.3.2.1 Connecting the Instrument to the Network
Preparing for Use
Connecting an External PC and Devices
This section describes how to configure the LAN interface. It includes the following topics:
●
Chapter 2.3.2.1, "Connecting the Instrument to the Network", on page 25
●
Chapter 2.3.2.2, "Assigning the IP Address", on page 26
●
Chapter 2.3.2.3, "Automatically Adding Instruments to the SGMA-GUI ",
on page 27
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.
In both cases, an IP address has to be assigned to the instrument and the computer,
see Chapter 2.3.2.2, "Assigning the IP Address", on page 26.
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.
Setting up a non- dedicated network (LAN) connection
► 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 dynamic TCP/IP configuration and
obtain all address information automatically.
Setting up a dedicated network connection
If your network does not support DHCP, you can set a dedicated network connection
between a stand-alone PC and a R&S SGS
Prerequisite: the computer and the R&S SGS are turned on and running.
1. Start the R&S SGMA-GUI.
2. Connect the computer and the R&S SGS with a LAN network cable.
3. Wait for about one minute for the automatic assignment of IP addresses to com-
plete.

2.3.2.2 Assigning the IP Address
Preparing for Use
Connecting an External PC and Devices
4. R&S SGMA-GUI main panel, select "Setup > Instruments".
5. In the "Configure Instruments" dialog, click "Scan".
The new instrument should appear with a Zeroconf IP address 169.254.xx.yy
6. Assign a static IP address to the instrument, see "Assigning a static IP address to
the R&S SGS" on page 26.
7. Assign a static IP address to the PC, see "Assigning a static IP address to your
Windows-PC network card" on page 27.
8. Edit the instrument settings, see Chapter 6.4.2.5, "How to Edit Instruments",
on page 69
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.
●
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,
see "Setting up a dedicated network connection" on page 25.
The R&S SGS uses the Zeroconf IP addresses 169.254.xxx.yyy., where xxx takes values between 1...254 and yyy the values in the value range 1...255; the subnet mask is
always 255.255.0.0. The IP address of the host must be within the same address area
for Zeroconf.
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.
Assigning a static IP address to the R&S SGS
Prerequisites: A connection is established between the R&S SGS and the controller
with installed SGMA-GUI.
For how to setup a LAN connection, see Chapter 2.3.2.1, "Connecting the Instrument
to the Network", on page 25.
For how to set up a USB connection, see "Setting up a USB connection from a PC to
the R&S SGS" on page 29.
