8 Remote Control Basics
This chapter provides basic information on operating R&S DigIConf via remote control.
Information on used term for R&S DigIConf
Throughout this description, the term “instrument” is used to indicate R&S DigIConf; the
terms “instrument”, “software” and R&S DigIConf are used interchangeably.
8.1 Remote Control Interfaces and Protocols
R&S DigIConf supports a LAN ( L ocal A rea N etwork) interface for remote control, using
socket communication protocol, i.e. Raw Socket (simple telnet). The interface is based
on TCP/IP with VISA resource string composed of:
TCPIP::<ipaddr>::<port>::SOCKET
No VISA installation is necessary to remote control while using socket communication.
For a description of the protocol refer to
​
chapter 8.1.2, "LAN interface" , on page 214.
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. R&S DigIConf 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 con-
cepts and definitions of SCPI.
Tables provide a fast overview of the bit assignment in the status registers. The tables
are supplemented by a comprehensive description of the status registers.
8.1.1 Messages
There are different types of instrument messages, depending on the direction they are
sent:
●
Commands
●
Responses
Structure and syntax of messages are described in
​
chapter 8.2, "SCPI Command Struc-
ture" , on page 222. A detailed description of all messages available for R&S DigIConf is
provided in
​
chapter 9, "Remote Control Commands" , on page 236.
