SCPI Command Hierarchy

The SCPI commands use a hierarchical structure for subsystem commands similar to a file system. For example, in :ROUT:CONN:RULE command, the hierarchy is as follows:

ROUT	root
CONN	sub-level 1
RULE	sub-level 2

The colon at the beginning of the command means root.

The colons between two command keywords means moving down to a lower level.

A semicolon enables two commands to be sent on the same line.

For example, :ROUT:CONN:RULE ALL,FREE;SEQ ALL,BBM is the same as the following two commands:

:ROUT:CONN:RULE ALL,FREE

:ROUT:CONN:SEQ ALL,BBM

So, using a semicolon reduces typing and simplifies the program.

A command terminator (such as carriage return) resets the path to root.
