STATus:QUEStionable:CURRent[:EVENt]?
The STATus:QUEStionable:CURRent:EVENt? query returns an integer representing
the value of the event register for the CURRent status group.
The event register latches positive transition events from the current condition
register. A positive transition occurs when a condition makes a transition from
unasserted to asserted (a low to a high state). Bits in the event register are latched,
and once set, they remain set until cleared by a
STATus:QUEStionable:CURRent:EVENt? query or *CLS (clear status). There is no
buffering; so while an event bit is set, subsequent events corresponding to that bit are
ignored. Event registers are read only.
