2-7 Notational Conventions

2-7 Notational Conventions
The SCPI interface standardizes command syntax and style to simplify the task of
programming across a wide range of instrumentation. As with any programming language,
the exact command keywords and command syntax must be used. Unrecognized commands
or improper syntax will not function.
Table 2-5. Notational Conventions
A colon links command keywords together to form commands. The colon is not an
:
actual part of the keyword, but is a signal to the SCPI interface parser. A colon must
precede a root keyword immediately following a semicolon (see
Examples" on page
A semicolon separates commands if multiple commands are placed on a single
;
program line.
Square brackets enclose one or more optional keywords.
[ ]
Braces enclose one or more keyword or command parameters that may be included
{ }
one or more times.
A vertical bar indicates "or" and is used to separate alternative parameter options.
|
Example: ON | OFF is the same as ON or OFF.
Angle brackets enclose parameter descriptions.
< >
Means "is defined as". For example: <a>::=<b><c> indicates that <b><c> can
::=
replace <a>.
Space, referred to as white space, must be used to separate keywords from their
sp
associated data parameters. It must not be used between keywords or inside
keywords.
Indicates a root command name.
