: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 positive transition in the Condition Register.
Comments
•
Bit 8 in the Condition Register is used by the System instrument
(command module) to indicate when an interrupt set up by the
DIAG:INTerrupt commands has been acknowledged.
•
Bit 8 in the Event Register generally is the only bit which is used. If
this bit is set when
STAT:OPER:EVENt? is sent, 256 is returned.
•
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.

:OPERation
:NTRansition
STATus:OPERation:NTRansition < unmask > sets the negative transition
mask. For each bit unmasked, a 1-to-0 transition of that bit in the associated
Condition Register will set the same bit in the associated Event Register.
