Setup > Instruments > Instrument> Edit").
2.3.2.2 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.
●
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 20.
Preparing for Use
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 Instru-
ment to the Network", on page 19.
For how to set up a USB connection, see "Setting up a USB connection from a
PC to the R&S SGS" on page 24.
1. Open "SGMA-GUI > Instrument > Setup > Network Settings" dialog.
2. Set the "Address Mode" to "Static".

SCPI (Standard Commands for Programmable Instruments)
SCPI commands are used for remote control. Commands that are not taken from
the SCPI standard follow the SCPI syntax rules. The instrument supports the
SCPI version 1999. The SCPI standard is based on standard IEEE 488.2 and
aims at the standardization of device-specific commands, error handling and the
status registers. The tutorial "Automatic Measurement Control - A tutorial on SCPI
and IEEE 488.2" from John M. Pieper (R&S order number 0002.3536.00) offers
detailed information on concepts and definitions of SCPI.
5.2.1.1 LAN Interface
To be integrated in a LAN, the instrument is equipped with a LAN interface, consisting of a connector, a network interface card and protocols.
For remote control via a network, the PC and the instrument must be connected
via the LAN interface to a common network with TCP/IP network protocol. They
are connected using a RJ45 cable (shielded or unshielded twisted-pair category
5). The TCP/IP network protocol and the associated network services are precon-
figured on the instrument. Software for instrument control and (for specified protocols only) the VISA program library must be installed on the controller.
Identifying instruments in a network
If several instruments are connected to the network, each instrument has its

VISA Resource Strings
The VISA resource string is required to establish a communication session
between the controller and the instrument in a LAN. The resource string is a
unique identifier, composed of the specific IP address of the instrument and some
network and VISA-specific keywords.
TCPIP::host address[::LAN device name][::INSTR]
●
TCPIP designates the network protocol used
●
host address is the IP address or host name of the device
●
[::LAN device name] defines the protocol and the instance number of a subinstrument:
●
[::INSTR] indicates the instrument resource class (optional)
The IP address (host address/computer name) is used by the programs to identify and control the instrument. It is automatically assigned by the DHCP server
the first time the device is registered on the network. Alternatively, you can also
assign its LAN device name.
Instrument Control
You can find the IP address in the "SGMA-GUI > Instrument Name > Setup >
Remote" dialog, and also adjust it manually, if necessary.
See below the characteristics of the VISA resource strings for the corresponding
interface protocols. The highlighted characters are crucial.
HiSLIP
TCPIP::host address::hislip0[::INSTR]
●
hislip0 HiSLIP device name, designates that the interface protocol HiSLIP is
used (mandatory).
hislip0 is composed of [::HiSLIP device name[,HiSLIP port]] and must be
assigned.
For details of the HiSLIP protocol, refer to "HiSLIP Protocol" on page 43.
VXI-11
TCPIP::host address[::inst0][::INSTR]
●
[::inst0] LAN device name, indicates that the VXI-11 protocol is used
(optional).
inst0 currently selects the VXI-11 protocol by default and can be omitted.

For details of the VXI-11 protocol, refer to ."VXI-11 Protocol" on page 44
Socket communication
TCPIP::host address::port::SOCKET
●
port determines the used port number
●
SOCKET indicates the raw network socket resource class
Socket communication requires the specification of the port (commonly referred
to as port number) and of "SOCKET" to complete the VISA resource string with
the associated protocol used.
The registered port for socket communication is port 5025.
See also "Socket Communication" on page 44.
Example:
Instrument Control
●
Instrument has the IP address 10.113.11.91; the valid resource string using
VXI-11 protocol is:
TCPIP::10.113.11.91::INSTR
●
The DNS host name is rssgs100a100021; the valid resource string is:
TCPIP::rssgs100a100021::hislip0 (HiSLIP)
TCPIP::rssgs100a100021::inst0 (VXI-11)
●
A raw socket connection can be established using:
TCPIP::10.113.11.91::5025::SOCKET
HiSLIP Protocol
The HiSLIP (High Speed LAN Instrument Protocol) is the successor protocol for
VXI-11 for TCP-based instruments specified by the IVI foundation. The protocol
uses two TCP sockets for a single connection - one for fast data transfer, the
other for non-sequential control commands (e.g. Device Clear or SRQ).
HiSLIP has the following characteristics:
●
High performance as with raw socket network connections
●
Compatible IEEE 488.2 support for Message Exchange Protocol, Device
Clear, Serial Poll, Remote/Local, Trigger, and Service Request
●
Uses a single IANA registered port (4880), which simplifies the configuration
of firewalls
●
Supports simultaneous access of multiple users by providing versatile locking
mechanisms

R&S®SGS100A
Network and Remote Control Operation
●
Usable for IPv6 or IPv4 networks
Using VXI-11, each operation is blocked until a VXI-11 device handshake
returns. However, using HiSLIP, data is sent to the device using the "fire
and forget" method with immediate return. Thus, a successful return of a
VISA operation such as viWrite() does not guarantee that the instrument has finished or started the requested command, but is delivered to the
TCP/IP buffers.
For more information see also the application note:
1MA208: Fast Remote Instrument Control with HiSLIP
VXI-11 Protocol
The VXI-11 standard is based on the ONC RPC (Open Network Computing
Remote Procedure Call) protocol which in turn relies on TCP/IP as the network/
transport layer. The TCP/IP network protocol and the associated network services
are preconfigured. TCP/IP ensures connection-oriented communication, where
the order of the exchanged messages is adhered to and interrupted links are
identified. With this protocol, messages cannot be lost.
Instrument Control
Socket Communication
An alternative way for remote control of the software is to establish a simple network communication using sockets. The socket communication, also referred to
as “Raw Ethernet communication”, does not require a VISA installation on the
remote controller side.
The simplest way to establish socket communication is to use the built-in telnet
program. The telnet program is part of every operating system and supports communication with the software on a command-by-command basis.
Socket connections are established on a specially defined port. The socket
address is a combination of the IP address or the host name of the instrument
and the number of the port configured for remote-control. All instruments use port
number 5025 for this purpose. The port is configured for communication on a
command-to-command basis and for remote control from a program running on a
connected PC.

5.2.1.2 USB Interface
For remote control via USB connection, the PC and the instrument must be connected via the USB interface. A USB connection requires the VISA library to be
installed. VISA detects and configures the R&S instrument automatically when
the USB connection is established. You do not have to install a separate driver.
You can retrieve the USB resource string from the "SGMA-GUI > Instrument
Name > Setup > Remote" dialog.
Example:
USB::0x0AAD::0x0088::100021::INSTR
0x0AAD is the vendor ID for Rohde&Schwarz
0x0088 is the product ID for the R&S SGS
100021 is the serial number of the particular instrument
Instrument Control
5.2.1.3 PCI Express Interface
A PCI Express (PCIe) connector is provided on the rear panel of the instrument.
Refer to chapter "Advanced Remote Control via PCIe" of the user manual for a
description of how to set up a remote control connection via PCIe and the permitted cables.
Via PCI Express some commands can be sent to the instrument with optimized
speed (memory-mapped remote control), e.g. frequency or level settings. This
allows minimum setup time.
You can retrieve the PCIe resource string from the "SGMA-GUI > Instrument
Name > Setup > Remote" dialog.
Example:
PCIe::0x162f::0x132e::100021::INSTR
0x162f is the vendor ID for Rohde&Schwarz
0x132e is the product ID for the R&S SGS
100021 is the serial number of the particular instrument

Network and Remote Control Operation
Using the PCIe interface for remote control of the instrument requires
extended knowledge and is described in section "Advanced Remote Control via PCIe" in the user manual.
5.2.1.4 GPIB Interface (IEC/IEEE Bus Interface)
The R&S SGS is not equipped with an IEC/IEEE bus interface.
To be able to control the instrument via the GPIB bus:
1. Connect a GPIB-to-LAN or a GPIB-to-USB adapter to the instrument.
2. Use a GPIB bus cable to connect the instrument and the controller.
3. Provide the GPIB bus card, the card drivers and the program libraries for the
programming language in the controller.
Instrument Control
4. In the "SGMA-GUI > Setup > Instruments > instrument name > Remote Control", set the "GPIB Address".
5. If the controller is equipped with several GPIB bus cards, define the used
"Board Number".
GPIB address
The controller must address the instrument with the GPIB bus channel. GPIB provides channel addresses from 0 to 30.
The GPIB resource string is GPIB::<address>[::INSTR], where:
●
GPIB denotes the used interface
●
<address> indicates the used channel
●
[::INSTR] indicates the instrument resource class (optional)
Note: If the VISA implementation supports the GPIB interface, you can optionally
define the VISA instrument control resource (INSTR). It is used to define the
basic operations and attributes for a device, such as reading, writing, or triggering.
Any connected IEC bus cable must be terminated by an instrument or controller.

5.2.2 Example: Remote Control over LAN Using the VXI-11 Pro-
tocol
In the following example, the program "Measurement & Automation Explorer"
from National Instruments is used on a Windows operating system to set up a
LAN remote control link and to start a remote control session. The remote control
program "Measurement & Automation Explorer" opens the connection to the
instrument (using VISA functionality) and then sends commands to and receives
device responses from the instrument.
A remote control connection requires a VISA installation but no additional hardware on the controller PC. The LAN I/O channel is selected at initialization time
using the VISA resource string (also referred to as "address string"). A VISA alias
(short name) is used to replace the complete resource string. The host address is
either the R&S SGS's computer name or its IP address.
Proceed as described in Chapter 2.3.2.2, "Assigning the IP Address", on page 21
to determine the relevant address information.
In this example, it is assumed that:
●
A LAN remote control link between the controller and the R&S SGS is
already set up.
For information on setting up the link, see Chapter 2.3.2, "Connecting a
Remote PC via LAN", on page 19.
●
A VISA and the "Measurement & Automation Explorer" program are
installed on the remote PC.
For detailed information, refer to section "Remote Control Basics" in the
user manual or to the online help of the "Measurement & Automation
Explorer" program.
To configure the controller
The instrument is preconfigured for networks using DHCP (dynamic host
configuration protocol). If this configuration is used, enter the computer
name in the position of the IP address.

Network and Remote Control Operation
The alias name should not be mistaken for the computer name. It is only used
for instrument identification within the program and displayed in the menu as
an option if there is an Ethernet link.
8. Confirm the settings with "Finish".
The instrument is configured and the settings are displayed in the "TCP/IP
Settings" tab.
Instrument Control
9. To test the connection, select "Validate".
A message indicates whether the link to the instrument can be set up or not.
If a connection cannot be set up, check whether the controller and the instrument are connected to the network (network cable) and are switched on. Correct spelling of the IP address or the computer name should be checked. For
further error location, inform the network administrator. In large networks,
specification of additional addresses may be required for link setup, e.g. gateway and subnet mask, which are known to the network administrator.
The instrument is now registered in the program and can be addressed via the
resource string or alias name.
To start a remote control session over LAN (using VXI-11)
1. Start the "Measurement & Automation Explorer" on the controller.
