:TER (Trigger Event Register)
(see page 782)
Query Syntax
:TER?
The :TER? query reads the Trigger Event Register. After the Trigger Event Register
is read, it is cleared. A one indicates a trigger has occurred. A zero indicates a
trigger has not occurred.
The Trigger Event Register is summarized in the TRG bit of the Status Byte
Register (STB). A Service Request (SRQ) can be generated when the TRG bit of the
Status Byte transitions, and the TRG bit is set in the Service Request Enable
register. The Trigger Event Register must be cleared each time you want a new
service request to be generated.
Return Format
