Example Reading the Event Register Mask
STAT:OPER:ENAB?

:OPERation[:EVENt]?
STATus:OPERation[:EVENt]? returns which bits in the event register (Operation
Status Group) are set. The event register indicates when there has been a transition
in the condition register.
Comments • Reading the event register clears the contents of the register. If the event
register is to be used to generate a service request (SRQ), you should clear the
register before enabling the SRQ (*SRE). This prevents an SRQ from
occurring due to a previous event.
