6 Root (:) Commands
:TER (Trigger Event Register)
(see page 1138)
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
<value><NL>
<value> ::= {1 | 0}; a 16-bit integer in NR1 format.
