COMMAND OVERVIEW 
The Command overview chapter lists all programming commands 
in functional order as well as alphabetical order. The command 
syntax section shows you the basic syntax rules you have to apply 
when using commands. 
Command Syntax 
 
SCPI (Standard Commands for Programmable 
Instruments) commands follow a tree-like 
structure, organized into nodes. Each level of 
the command tree is a node. Each keyword in a 
SCPI command represents each node in the 
command tree. Each keyword (node) of a SCPI 
command is separated by a colon (:). 
For example, the diagram below shows an SCPI 
sub-structure and a command example.
