Symbol Description
1. Colon :
A command usually begins with a colon (:) which is also used to separate the
command keyword from a lower-level keyword.
2. Question Mark ?
A command followed by a question mark (?) is used to query the function under this
command. A query command usually has different data, and these data are separated
by a space. However some commands do not have any data.
3. Comma ,
A “,” is a used to separate different type of parameters that contained in a command,
such as:
:DATAlog:CONFigure:FUNCtion {<DCV|DCI|RESistance|FRESistance>,<range>}
4. Braces { }
The contents enclosed in braces are parameters. If the parameters enclosed in braces
are separated by a vertical line (|), only one element can be selected at a time. For
example, {ON|OFF} indicates that either ON or OFF can be used.
5. Triangle Brackets < >
An item enclosed in (< >) should be an effective value and this value is used as a
parameter.
6. Square brackets [ ]
The parameters or command keywords that enclosed in square bracket ([ ]) are
optional or could be ignored. The square bracket ([ ]) will not be placed at an actual
command. If none of the parameters are specified, the system will use a default. For
example:
CONFigure[:VOLTage][:DC] [{<range>|AUTO|MIN|MAX|DEF}[,{<resolution>|MIN|MAX|DEF}]]
In this command, there are many square brackets, if you set all of the parameters to
their defaults, the command could be abbreviated to
CONFigure
