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
SCPI commands perform functions like closing switches, making measurements,
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?
is the root command,
[ROUTe:]
parameters, and
:MODE?
*STB?
and are second level commands with
CLOSe SCAN
is a third level command.
