Overview of the remote control interfaces
The following table gives a detailed overview on the supported interfaces.
Table 4-11: Remote control interfaces and protocols
Interface
Protocols, VISA
*)
address string
Remarks
GPIB (IEC/
IEEE Bus
Interface)
VISA
*)
address string:
GPIB::primary
address[::INSTR]
(no secondary address)
The GPIB bus interface according to standard IEC 625.1/IEEE
488.1 is located at the rear panel of the instrument.
Define the address in the GPIB dialog box, described in chap-
ter 4.7.1.2, "GPIB settings", on page 146.
For a description of the interface refer to chapter A.1, "GPIB Bus
Interface", on page 349.
USB
VISA
*)
address string:
USB::<vendor
ID>::<product
ID>::<serial num-
ber>[::INSTR]
The instrument provides a USB connector at the rear panel.
Refer to chapter 4.7.1.3, "USB settings", on page 146.
For a description of the interface refer to chapter A.4, "USB inter-
face", on page 363.
Local Area
Network
(LAN)
VXI-11
VISA
*)
address string:
TCPIP::host
address[::LAN device
name][::INSTR]
A LAN connector is located at the rear panel of the instrument.
The interface is based on TCP/IP and supports VXI-11 protocol,
see chapter 4.7.1.4, "VXI11 settings", on page 147 for setting
the IP address.
For description of the interface refer to chapter A.2.1, "VXI11
protocol", on page 353.

Network
(LAN)
Ethernet, socket com-
munication (e.g.Raw
Ethernet, simple telnet)
VISA
*)
address string:
TCPIP::host
address[::LAN device
name][::INSTR]
A LAN connector is located at the rear panel of the instrument.
The interface is based on TCP/IP and supports Ethernet, socket
communication, see chapter 4.7.1.5, "Raw Ethernet (socket
communication) settings", on page 148 for setting the IP
address.
For description of the interface refer to chapter A.2.2, "Connec-
tion setup", on page 354.

) VISA is a standardized software interface library providing input and output functions to communicate with
instruments. A VISA installation on the controller is a prerequisite for remote control over USB or LAN when
using VXI-11 protocol. However, no VISA installation is necessary to remote control while using Ethernet
(socket communication), see also chapter A.2.2, "Connection setup", on page 354.
4.7.1.1 Selecting the remote control interface
This section describes the configuration of the remote control interfaces.
For information on how to set up a remote control connection via the different interfaces,
see chapter 5.2, "Connecting a Controller to the Base Unit", on page 168.
For background information on the interfaces, see chapter A, "Remote control interfa-
ces", on page 349.
