SCPI Commands Overview SCPI
Command Format
SCPI is an ASCII based command language designed for test and
measurement instruments. SCPI commands uses a hierarchical
structure (tree system), and is divided into different subsystems.
Each subsystem is defined by a different root keyword. Each
command consists of a root keyword and one or more hierarchical
key words separated by a colon “:” and followed by a parameter.
There is always a space between the keywords and the parameters.
Any commands followed by a question mark (?) are queries.
For Example:
:SYSTem:BEEPer:STATe {0|1|OFF|ON}
:SYSTem:BEEPer:STATe?
SYSTem is the root level keyword and BEEPer and STATe are the
secondary and tertiary level keywords. All levels have a “:”
separating each keyword. Parameters are enclosed in “{ }”.
The commands SYSTem:BEEPer:STATe has {0|1|OFF|ON } as
parameters. The parameters are separated with a space.
SYSTem:BEEPer:STATe? indicates that the command is a query.
In addition some commands have multiple parameters that are
usually separated by a comma “,”.
For example: :STATus:QUEue:ENABle (-110:-222, -220).
