Figure 8-5 COMParator subsystem command tree
The [:STATe] command sets the comparator function to ON or OFF. The [:STATe]? query returns the current
comparator state.
Command syntax:
ON
COMParator[:STATe] OFF
1
0
Where,
1 (decimal49) is equal to ON; the comparator is ON.
0 (decimal48) is equal to OFF; the comparator is OFF.
For example: WrtCmd( “COMP ON” ); turn on the comparator function.
Query syntax: COMParator[:STATe]
？
Return format:
Off
<NL^END>

The :AREAsize[:STATe] command sets the Areasize comparator function to ON or OFF.
The :AREAsize[:STATe]
？
query returns the current Areasize comparator state.
