Symbol Description
The following four symbols are not the content of SCPI commands but usually used in
instances of the parameters from Explanation commands.
1. Braces { }
The parameters enclosed in braces are optional and can be ignored or set one or
more times, such as:
[:SENSe]:CORRection:CSET<n>:DATA
<freq>,<rel_ampl>{,<freq>,<rel_ampl>}
In the command above, you can ignore parameters {,<freq>,<rel_ampl>} or
assign them one or more values.
2. Vertical Bar |
The vartical bar separates two or more optional parameters. When you send a
command, at least one of the parameters should be selected, such as
:DISPlay:MENU:STATe OFF|ON|0|1
In the command above, you can select “OFF”, “ON”, “0” or “1”.
3. Square Brackets [ ]
The contents such as keywords enclosed in square brackets could be omitted, but
all of them would be executed regardless whether they were omitted such as:
[:SENSe]:CORRection:OFFSet[:MAGNitude]?
The following three commands serve a similar purpose:
:CORRection:OFFSet?
:CORRection:OFFSet:MAGNitude?
:SENSe:CORRection:OFFSet?
4. Triangle Brackets < >
The parameter enclosed in triangle brackets must be an effective value such as
:
:DISPlay:BRIGtness <integer>
:DISPlay:BRIGtness 10
