COMMAND :STATus:OPERation[:EVENt]?
Queries the status of the Operation Event Status Register.
QUERY RESPONSE Numeric data transferred as ASCII bytes in <NR1> format.
Range is 0 to 32,767.
The query response value is an integer formed by the binary weighting
of bits. The value of unused bits is zero.
COMMENTS Each event bit in the Operation Event Status Register corresponds to a
specific condition bit in the Operation Condition Status Register; this
allows the Operation Event Status Register to detect changes in
conditions.
An event becomes TRUE when the associated condition makes the
transition specified by the transition filters.
The event bits, once set, are “sticky”—i.e., they cannot be cleared until
they are read, even if they do not reflect the current status of a related
condition.
The Operation Event Status Register is cleared by *CLS, by
:STAT:OPER[:EVEN]?, and at power-on.
