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 synthesizer in both the graphical and tabular
formats.

If a command requires one or more parameters in addition to the

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
