Subsystem Commands Programming with SCPI
2-6 PN: 10580-00306 Rev. E MS20xxC PM
All MS20xxC SCPI commands, except the :ABORt command, have one or more subcommands
(keywords) associated with them to further define the instrument function to be controlled.
The subcommand keywords may also have one or more associated subcommands (keywords).
Each subcommand level adds another layer to the command tree. The command keyword and
its associated subcommand keywords form a portion of the command tree called a command
subsystem. The :DISPlay command subsystem is shown in Figure 2-2.
A colon (:) separates each subsystem. For example, the command
:DISPlay:WINDow:Trace MEMory sets the window to display memory trace. Trace is part
of the :WINDow subsystem, which is part of the :DISPlay subsystem. Y is also part of the
:DISPlay:WINDow:Trace{1-4} subsystem.
