SCPI Commands
This chapter explains in detail the SCPI commands used by the electronic load. The electronic load
conforms to SCPI Version 1995.0.
3.1 Language Dictionary
This section describes the syntax and parameters for all the IEEE 488.2 SCPI subsystem and common
commands used by the electronic loads. Since the SCPI syntax remains the same for all programming
languages, the examples given for each command are generic.
Syntax Forms
Syntax definitions use the long form, but only short form headers (or
"keywords") appear in the examples. Use the long form to help make your
program self-documenting.
Parameters
Most commands require a parameter and all queries will return a parameter.
The range for a parameter may vary according to the model of electronic
load. Parameters for all models are listed in the Specifications table in the
User’s Guide.
Related Commands
Where appropriate, related commands or queries are included. These are
listed because they are either directly related by function, or because reading
about them will clarify or enhance your understanding of the original
command or query.
Order of Presentation
The dictionary is organized as follows:
• Subsystem commands, arranged by subsystem
• IEEE 488.2 common commands
Common Commands
Common commands begin with an * and consist of three letters (command) or three letters and a ?
(query). They are defined by the IEEE 488.2 standard to perform common interface functions. Common
commands and queries are categorized under System, Status, or Trigger functions and are listed at the
end of this chapter.
Subsystem Commands
Subsystem commands are specific to functions. They can be a single command or a group of
