programming commands: IEEE 488 common commands
and Standard Commands for Programmable Instruments
(SCPI). Some commands are device-specific to the
meter. They are not included in the version 1999.0 of the
SCPI standard. However, these commands are designed
with the SCPI format in mind and they follow the syntax
rules of the standard.
Common Command Format
The IEEE 488 standard defines the common
commands as commands that perform functions like
reset and system query. Common commands usually
come with the asterisk "*" character, and may include
parameters. Some examples of Common command like:
*IDN?, *GTL, *LLO.
SCPI Command Format and Query
Format
The SCPI commands control instrument functions.
A subsystem command has a hierarchical structure that
usually consists of a top-level (or root) keyword, one or
more lower level keywords, and parameters. The
following example shows a command and its associated
query:
