Commands are separated into two types: IEEE 488.2 Common Commands
and SCPI Commands.
The IEEE 488.2 standard defines the Common commands that perform
functions like reset, self-test, status byte query, etc. Common commands
are four or five characters in length, always begin with the asterisk character
(*), and may include one or more parameters. The command keyword is
separated from the first parameter by a space character. Some examples of
Common commands are shown below:
*RST *ESR 32 *STB?
SCPI commands perform functions like closing switches, or querying
instrument states or retrieving data. A subsystem command structure is a
hierarchical structure that usually consists of a top level (or root) command,
one or more lower level commands, and their parameters. The following
example shows part of a typical subsystem:
[ROUTe:]
CLOSe <channel_list>
SCAN <channel_list>
:MODE?
ROUTe: is the root command, CLOSe and SCAN are second level
commands with parameters, and :MODE? is a third level command.
