Symbol Instruction
The following symbols are not “real” parts of the commands, but they are usually
used to assist to explain the parameters containd in a command line.
1. Braces { }
The parameters enclosed in a command line must be selected. When several
elements separated by a vertical line (|) are enclosed by braces, { }, only one
element may be selected, for example:
:MEASure:TOTal {ON|OFF},
Thereinto, {ON|OFF} indicates that only ON or OFF may be selected, not both.
2. Square Brackets [ ]
Items enclosed in square brackets [ ] are optional, for example:
:TIMebase[:DELayed]:OFFSet <offset>
Thereinto, [:DELayed] could be omitted.
3. Triangle Brackets < >
Items enclosed in < > should be replaced by an effective value, for example:
:DISPlay:BRIGhtness <ncount>
Thereinto, < ncount > must be a numerical value such as 25.
