SCPI Command Basics 5-3
Command
Keyword Long
Form and Short
Form
Each keyword defined by SCPI has both a
long form
and a
short
form
. The long form is formed by using all letters shown in the
keyword. The short form is formed by using only those letters
shown in upper-case in the command tree.
The short form is normally three or four letters in length, and ends
with a consonant where possible.
For example, the ROUTE keyword may be specified by either of
the following:
ROUT
ROUTE
since the final “e” is shown in lower-case in the command tree.
Only the long form or short form may be used. For example, the
keyword “DEFINE” is shown as:
DEFine
Therefore, the following two command keywords are valid:
DEFINE
DEF
But the keywords
DE
DEFI
DEFIN
are NOT valid.
Case Sensitivity
Command keywords are
NOT
case sensitive. Command
parameters are not case sensitive, unless the parameter is string
data enclosed in quotes.
For example, the following commands are equivalent:
CLOSE
Close
