Syntax
SCPI commands present a hierarchical tree structure and contain multiple sub-
systems, each of which is made up of a root keyword and one or more sub-
keywords. The command string usually starts with ":", the keywords are
separated by ":" and are followed by the parameter settings available, "?" is
added at the end of the command string to indicate query and the command
and parameter are separated by "space".
For example,
:COUPling:AMPL:DEViation <deviation>
:COUPling:AMPL:DEViation?
COUPling is the root keyword of the command. AMPL and DEViation are the
second-level and third-level keywords respectively. The command string starts
with ":" which separates the multiple-level keywords. <deviation> represents
the parameter available for setting, "?" represents query and the command
:COUPling:AMPL:DEViation and parameter <deviation> are separated by
"space".
"," is generally used for separating different parameters contained in the same
command, for example,
:MMEMory:COPY <directory_name>,<file_name>
