Command Tree
The SCPI standard is an ASCII based standard that
defines the command syntax and structure for
programmable instruments.
Commands are based on a hierarchical tree
structure. Each command keyword is a node on
the command tree with the first keyword as the
root node. Each sub node is separated with a
colon.
Shown below is a section of the SOURce[1|2] root
node and the :PM and :PULSe sub nodes.
