7.5 Overview of Messages
The information that is exchanged between the computer and the PAT is called a
message.
The PAT uses the SCPI language for the messages.
There are two types of messages, commands that are sent from the computer to the
PAT and responses that are sent from the PAT to the computer.
Commands are used to execute functions of the PAT, change settings, and query
settings and status. Responses return the settings and status of the PAT.
Command hierarchy
SCPI is an ASCII-based command language designed for test and measurement
devices. The command hierarchy is structured around the common root or node,
which is the construction block of the SCPI sub system. A command consists of a
program header, parameters, and punctuations.
The hierarchy is explained using the SOURce subsystem as an example.
A higher node is separated from a lower node using a colon (:).
