Remote GPIB Interface

5.2.1 Command Structure
The GPIB interface allows commands, which tell the instrument to take a
specific action, and queries, which ask the instrument to return information.
Commands are composed of syntactic elements:
•
Header – the command name; if it ends with a question mark, the
command is a query.
•
Delimiter – a space, colon (:), comma (,), or semi-colon (;) which
breaks the message into segments for the instrument to process.
• Link – a command sub-function. Not all commands have links.
•
Argument – a quantity, quality, restriction, or limit associated with the
header or link.
Commands are case insensitive, although they are documented in an
uppercase and lowercase manner that indicates which minimum characters
are required to make the command. The commands can be shortened to the
minimum length illustrated by the uppercase letters in the documentation.
