Command Syntax 
 
SCPI (Standard Commands for Programmable

organized into nodes. Each level of  the command tree is 
a node. Each keyword in an SCPI command represents 
each node in the command tree. Each keyword (node) of  
an SCPI command is separated by a colon (:).

unit and a query receives data or status information from
