10  SCPI Command Reference 
Where appropriate, related commands or queries are included.  These are listed because 
they are either directly related by function, or because reading about them will clarify or 
enhance your understanding of the original command or query. 
This chapter is organized as follows: 
Subsystem commands, arranged by subsystem 
IEEE 488.2 common commands 
10.1  Subsystem Commands 
Subsystem commands are specific to AC source functions.  They can be a single command 
or a group of commands.  The groups are comprised of commands that extend one or more 
levels below the root.  The description of common commands follows the description of the 
subsystem commands. 
The subsystem command groups are listed in alphabetical order and the commands within 
each subsystem are grouped alphabetically under the subsystem. Commands followed by a 
question mark (?) take only the query form.  When commands take both the command and 
query form, this is noted in the syntax descriptions.
