The optional GPIB bus interface according to
standard IEC 625.1/IEEE 488.1 is at the rear
panel of the instrument.
For a description of the interface, see Chap-
ter 10.2.3, "GPIB interface (IEC/IEEE bus inter-
face)", on page 145.

) VISA (Virtual Instrument Software Architecture) 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 LAN and USB inter-
face. For remote control over socket communication VISA installation is optional. When using socket communication or the GPIB
interface, VISA installation is optional. For basic information, see Remote control via SCPI.
Rohde & Schwarz provides the standardized I/O software library R&S VISA for down-
load at the Rohde & Schwarz website http://www.rohde-schwarz.com/rsvisa.

10.2.1 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.
The network card can be operated with the following interfaces:
●
10 Mbit/s Ethernet IEEE 802.3
●
100 Mbit/s Ethernet IEEE 802.3u
For remote control, the PC and the instrument must be connected over the LAN inter-
faces to a common network with TCP/IP network protocol. The instruments are con-
nected using a commercial RJ45 cable (shielded or unshielded twisted-pair category
5). The TCP/IP network protocol and the associated network services are preconfig-
ured 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 own IP
address and associated resource string. The controller identifies these instruments by
the resource string.
10.2.1.1 VISA resource strings
The VISA resource string is required to establish a communication session between
the controller and the instrument in the LAN. The resource string is a unique identifier,
