EVENT STATUS ENABLE, sets the bits of the event status enable register

EVENT STATUS QUERY, queries the contents of the event status register.
Device-specific commands
Hierarchy:
Device-specific commands are of hierarchical structure (see Fig. 5.40 ). The different
levels are represented 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 command system
SENSe
.
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.
