SCPI Command Hierarchy

SCPI is an ASCII-based command language designed for use in high-technology
test and measurement equipment. The command structure is organized around
common roots, or nodes, which are the building blocks of SCPI subsystems. An
example of a common root is CALibration, and some of the commands that reside
in the CALibration subsystem are shown below.

CALibration

:CURRent

[:DATA]

:LEVel {MIN|MAX}

[:SECure]

:CODE

:STATe {OFF|ON},

:STATe?

CALibration is the root keyword of the command. CURRent and SECure are
second-level keywords, and DATA, LEVel, CODE, and STATe, are third-level
keywords. A colon (:) is used to separate a command keyword from a lower-level
keyword.
