Hierarchy

Device-specific commands are of hierarchical structure. The different levels are repre-
sented by combined headers. Headers of the highest level (root level) have only one
key word. This key word denotes a complete command system.
Example:
SENSe
This key word denotes the SENSe command system.
For commands of lower levels, the complete path has to be specified, starting on the
left with the highest level, the individual key words being separated by a colon ":".
Example:
SENSe:FREQuency:SPAN 10MHZ
This command lies in the third level of the SENSe system. It sets the frequency span.
