6 Remote Control Basics
This chapter provides basic information on operating an instrument via remote control.
6.1 Remote Control Interfaces and Protocols
The instrument supports different interfaces for remote control. The following table
gives an overview.
Table 6-1: Remote control interfaces and protocols
Interface
Protocols, VISA *) address string
Remarks
Local Area Net-
work (LAN) Protocols:
●
VXI-11
VISA
*) address string:
TCPIP::host address[::
LAN device name][::INSTR]
●
socket communication (Raw Ethernet,
simple telnet)
VISA
*) address string:
TCPIP::host address[::
LAN device name]::<port>::
SOCKET
A LAN connector is located on the front or rear panel of the
instrument, or both.
The interface is based on TCP/IP and supports various proto-
cols.
For a description of the protocols refer to:
●
Chapter 6.1.3.2, "VXI-11 Protocol" , on page 443
●
Chapter 6.1.3.3, "Socket Communication" , on page 443
GPIB (IEC/IEEE
Bus Interface)
VISA
*)
address string:
GPIB::primary address[::INSTR]
(no secondary address)
Optional GPIB bus interfaces according to standard IEC 625.1/
IEEE 488.1 are located on the rear panel of the instrument.
For a description of the interface refer to Chapter 6.1.4, "GPIB
Interface (IEC/IEEE Bus Interface)" , on page 444.
Note: Within this interface description, the term GPIB is used as
a synonym for the IEC/IEEE bus interface.
* ) 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 LAN (when using VXI-11 or HiSLIP protocol), USB and serial
interface. For remote control via socket communication VISA installation is optional. For more information, see
Chapter 6.1.1,
"VISA Libraries" , on page 440.
Rohde & Schwarz provides the standardized I/O software library R&S VISA for com-
munication via TCP/IP (LAN: HiSlip, VXI-11 and raw socket), USB (USBTMC) or serial
interfaces.
R&S
VISA is available for download at the Rohde & Schwarz website http://

How to configure the remote control interfaces, see Chapter 6.2, "Starting a Remote
Control Session" , on page 446.
SCPI (Standard Commands for Programmable Instruments)
SCPI commands - messages - 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
