Remote Control Methods
1. User-defined Programming
Users can use the SCPI (Standard Commands for Programmable Instruments) commands listed in
chapter 2 “Command System” of this manual to program and control the instrument in various
development environments (such as Visual C++, Visual Basic, LabVIEW and so on). For details, refer
to the introductions in chapter 4 “Programming Demos”.
2. Send SCPI Commands via the PC Software
You can control the signal generator remotely by sending the SCPI commands via the PC software
(Ultra Sigma) provided by
RIGOL . Besides, you can also control the instrument using the
“Measurement & Automation Explorer” of NI (National Instruments Corporation) or the “Agilent IO
Libraries Suite” of Agilent (Agilent Technologies, Inc.).
SCPI Command Overview
SCPI (Standard Commands for Programmable Instruments) is a standardized instrument programming
language that is built upon the standard IEEE488.1 and IEEE 488.2 and conforms to various standards
(such as the floating point operation rule in IEEE754 standard, ISO646 7-bit coded character for
information interchange (equivalent to ASCll programming)). This section introduces the syntax, symbols,
parameters and abbreviation rules of the SCPI commands.
Syntax
The SCPI commands provide a hierarchical tree structure and include multiple subsystems. Each command
subsystem consists of a root keyword and one or more sub-keywords.The command string usually starts
with ":"; the keywords are separated by ":" and are followed by the parameter settings available; "?" is
added at the end of the command string to indicate query; the command and parameter are separated by
space.
For example,
:SYSTem:COMMunicate:LAN:IPADdress
:SYSTem:COMMunicate:LAN:IPADdress?
SYSTem is the root keyword of the command. COMMunicate, LAN and IPADdress are the second-level,
third-level and forth-level keywords respectively. The command string starts with ":" which is also used to
separate the multiple-level keywords. represents the parameters available for setting. "?"
represents query; the instrument returns the corresponding information (the input value or internal setting
value of the instrument) when recieving the query command. The
command :SYSTem:COMMunicate:LAN:IPADdress and parameter are separated by space.
"," is generally used for separating multiple parameters contained in the same command, for example,
:DISPlay:TEXT[:SET] [,x[,y]]
