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.
Command types
Commands can be separated in to three distinc
types, simple commands, compound commands
and queries.
Simple
A single command with/without
a parameter
Example *OPC
Compound
Two or more commands
separated by a colon (:)
with/without a parameter
