Command Types Three types of commands are used:

•Common (*) Commands — See "Introduction to Common (*) Commands" on page 63 for more information.

•Root Level (:) Commands — See "Introduction to Root (:) Commands" on page 88 for more information.

•Subsystem Commands — Subsystem commands are grouped together under a common node of the "Command Tree" on page 535, such as the :TIMebase commands. Only one subsystem may be selected at any given time. When the instrument is initially turned on, the command parser is set to the root of the command tree; therefore, no subsystem is selected.
