Common commands
Common commands are commands that are common to all devices on the bus. These
commands are designated and defined by the IEEE-488.2 standard.
Generally, these commands are sent as one or more ASCII characters that tell the device to
perform a common operation, such as reset. The IEEE-488 bus treats these commands as data
in that ATN is false when the commands are transmitted.
SCPI commands
SCPI commands are commands that are particular to each device on the bus. These
commands are designated by the instrument manufacturer and are based on the instrument
model defined by the Standard Commands for Programmable Instruments (SCPI) Consortium’s
SCPI standard.
Generally, these commands are sent as one or more ASCII characters that tell the device to
perform a particular operation, such as setting a range or closing a relay. The IEEE-488 bus
treats these commands as data in that ATN is false when the commands are transmitted.
Command codes
Command codes for the various commands that use the data lines are summarized in
Figure E-3. Hexadecimal and the decimal values for the various commands are listed in
Table E-2.
