Command Syntax
The programming syntax used with the GLC-9000 conforms to
IEEE488.2 and SCPI standards. SCPI (Standard computer
Programming Interface) is designed for test and measurement
instruments. It is based upon ASCII instrument command codes.
SCPI command syntax is based upon a “tree” hierarchy. In this
system, related commands are grouped together at a common root
level. Below, the “tree” hierarchy of the CONFigure command is
shown.

The command syntax is made up of short and long command forms.
Any commands written in upper case, indicates the short command
form, any command written in lower case indicates the long
command form. Even though the commands are written in upper
and lower case to distinguish between the command forms, either
short or long command forms can be written in either upper or
lower case. For example, the above syntax structure CONF and
CONFIGURE are both acceptable formats, in upper or lower case
letters. However, other forms of abbreviation such as CON and
CONFigur are erroneous.
