3.7.4 UNDERSTANDING THE COMMAND STRUCTURE
Understanding the command structure requires an understanding of the subsystem command
tree illustrated in Figure 3-10. The “root” is located at the top left corner of the diagram. The
parser goes to the root if:
• a message terminator is recognized by the parser
• a root specifier is recognized by the parser
Starting at the root, there are various branches or paths corresponding to the subsystems. The
root keywords for the KLN 750W Power Supply are :CALibrate, :DISPlay, :FETCh, :OUTPut,
:SOURce and :SYSTem.
