Case sensitivity
Common commands and SCPI commands are not case sensitive. You can use upper or
lower case and any case combination. Examples:
*RST = *rst
DATA? = data?
SYSTem:PRESet = system:preset
klqb
Using all upper case will result in slightly faster command response times.
Long-form and short-form versions
A SCPI command word can be sent in its long-form or short-form version. The command
subsystem tables in
Section 15 provide the long-form version. However, the short-form
version is indicated by upper case characters. Examples:
SYSTem:PRESet long-form
SYST:PRES short-form
SYSTem:PRES long-form and short-form combination
Note that each command word must be in long-form or short-form and not something in
between. For example, SYSTe:PRESe is illegal and will generate a -113 Undefined
Header error. The command will not be executed.
Short-form rules
Use the following rules to determine the short-form version of any SCPI command:
• If the length of the command word is four letters or less, no short form version
exists. Example:
:auto = :auto
These rules apply to command words that exceed four letters:
• If the fourth letter of the command word is a vowel (including “y”), delete it and all
the letters after it. Example
immediate = imm
• If the fourth letter of the command word is a consonant, retain it but drop all the
letters after it. Example:
format = form
