SCPI Syntax Rules
Use either short or long forms
Commands and queries may be sent in either long form (complete spelling) or
short form (abbreviated spelling). The description of each command in this
manual shows both versions; the extra characters for the long form are shown
in lowercase. The following is a long form of a command:
sendMessaage":SENSe:WAVelength:STARt?"
And this is the short form of the same command:
sendMessaage":SENS:WAV:STAR?"
Programs written in long form are easily read and are almost self-document-
ing. Using short form commands conserves the amount of controller memory
needed for program storage and reduces the amount of I/O activity.
The rules for creating short forms from the long form are as follows:
The mnemonic is the first four characters of the keyword unless the fourth
character is a vowel, in which case the mnemonic is the first three char-
acters of the keyword.
This rule is not used if the length of the keyword is exactly four characters.

You can use upper or lowercase letters
Program headers can be sent using any combination of uppercase or lower-
case ASCII characters. In commands, uppercase lettering indicates that the
uppercase portion of the command is the short form of the command. For
example, in the command WAVelength, WAV is the short form.
Instrument responses, however, are always returned in uppercase.
