Command Types
Commands are separated into two types: IEEE 488.2 Common Commands
and SCPI Commands.
Common
Command Format
The IEEE 488.2 standard defines the common commands that perform
functions such as reset, self-test, status byte query, and so on. 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 Command
Format
The SCPI commands perform functions such as making measurements,
querying instrument states, or retrieving data. A command subsystem
structure is a hierarchical structure that usually consists of a top level (or
root) command, one or more low-level commands, and their parameters.
The following example shows a typical subsystem:
CALibration
:LFRequency <
frequency>
:LFRequency? [MIN | MAX]
:ZERO:AUTO <
mode>
:ZERO:AUTO?
CALibration
is the root command, LFRequency, LFRequency?, and ZERO
are second level commands, and AUTO and AUTO? are third level
commands.
Command Separator A colon (:) always separates one command from the next lower level
command as shown below:
