Query Syntax
:AER?
The AER query reads the Arm Event Register. After the Arm Event Register is read,
it is cleared. A "1" indicates the trigger system is in the armed state, ready to
accept a trigger.
The Armed Event Register is summarized in the Wait Trig bit of the Operation
Status Event Register. A Service Request can be generated when the Wait Trig bit
transitions and the appropriate enable bits have been set in the Operation Status
Enable Register (OPEE) and the Service Request Enable Register (SRE).
