Remote Operation 12-13
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
Long-form and short-form versions
A SCPI command word can be sent in its long-form or short-form version. The command
tables in this manual use the long-form version. However, the short-form version is indicated by
upper case characters.
:SYSTem:PRESet long-form
:SYST:PRES short form
:SYSTem:PRES long-form and short-form combination
Note that each command word must be in either long-form or short-form. For example,
:SYSTe:PRESe is illegal and will generate an 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.
:auto = :auto
These rules apply to command words that exceed four letters:
• If the fourth letter of the command word is a vowel, delete it and all the letters after it.
immediate = :imm
• If the fourth letter of the command word is a consonant, retain it but drop all the letters
after it.
:format = :form
• If the command contains a question mark (?) or a non-optional number included in the
command word, you must include it in the short-form version.
:delay? = :del?
• Command words or characters that are enclosed in brackets ([ ]) are optional and need
not be included in the program message.
