7.2Command Structure
The SCPI command form a hierarchical structure. Commands are divided into groups, each of which consists of com- mands of similar functions, and each group forms a hierarchical structure called the subsystem.
This specification expresses these subsystems by the command tree as shown below.
SCPI allows the same headers to be present in a tree and the difference in the location of the header corresponds to the difference in the function. Therefore, a command must be described in a full path up to the header to be used.
