Overview of Messages
The information that is exchanged between the controller (computer) and the device
(KFM2151) is called a message.
The KFM2151 uses the SCPI language for the messages.
There are two types of messages, commands that are sent from the computer to the
KFM2151 and responses that are sent from the KFM2151 to the computer.
Command hierarchy
SCPI commands are ASCII-based commands 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 CHANnel subsystem as an example.
A higher node is separated from a lower node using a colon (:).
