Syntax
SCPI commands present a hierarchical tree structure and have more sub-systems.
Each sub-system contains a root keyword and one or more sub-keywords. A command
line usually begins with a “:” which is also used to separate different keywords;
parameters are permitted to follow the keyword; “?” appeared following a command
line denotes to query; “space” is used to separate the command and parameter.
For example:
:CALCulate:BANDwidth:NDB <rel_ampl>
:CALCulate:BANDwidth:NDB?
CALCulate is the root keyword of the command above. BANDwidth and NDB are
the second and third keyword separately. The command line begins with a “ : ” and
uses “ : ” to separate each keyword; <rel_ampl> denotes a assignable parameter;
“ ? ” denotes to query; command “ :CALCulate:BANDwidth:NDB ” and prarameter
<rel_ampl> are separated by a space.
“,” is generally used for separating different parameters contained in the same
command, such as:
:SYSTem:DATE <year>,<month>,<day>
