Subsystem Command
These paragraphs introduce a more complete, compact way of
Tables
documenting subsystems using a tabular format. The command
table contains more information than just the command hierarchy
shown in a graphical tree. In particular, these tables list command
parameters for each command and response data formats for queries.
To begin this exploration of command tables, consider a simplified
SWEep subsystem for the swept CW generator in both the graphical
and tabular formats.

Reading the Command Table
Note the three columns in the command table labeled
Command,
Parameters,
and
Parameter Type.
Commands closest to the root
level are at the top of the table. Commands in square brackets
are implied commands, which are discussed in later paragraphs.
If
a command requires one or more parameters in addition to the
keyword, the parameter names are listed adjacent to the command.
Parameters in square brackets are optional parameters, which are
discussed in later paragraphs. If the parameter is not in square
brackets, it is required and you must send a valid setting for it with
