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
Network
(LAN) Protocols:
●
VXI-11
●
socket communica-
tion (Raw Ethernet,
simple telnet)
VISA
*)
address string:
TCPIP::host
address[::LAN device
name][::INSTR]
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 protocols.
For a description of the protocols refer to:
● ​
chapter 6.1.3.1, "VXI-11 Protocol" , on page 168
● ​
chapter 6.1.3.2, "Socket Communication" , on page 168
USB
VISA *) address string:
USB::<vendor
ID>::<product
ID>::<serial num-
ber>[::INSTR]
USB connectors are located on the front or the rear panel of the
instrument, or both.
For a description of the interface refer to
​
chapter 6.1.4, "USB
Interface" , on page 169
Serial Inter-
face
VISA

address string:
ASRL[0-9][::INSTR]
For a description of the interface refer to
​
chapter 6.1.5, "Serial
Interface" , on page 169.
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 6.1.6, "GPIB
Interface (IEC/IEEE Bus Interface)" , on page 170.
* ) 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 protocol), USB and serial interface. However, no VISA installation is necessary to remote control while
using socket communication. For more information, see
​
chapter 6.1.1, "VISA Libraries" , on page 166.
Within this interface description, the term GPIB is used as a synonym for the IEC/IEEE
bus interface.
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 at the
