STATus:OPERation[:EVENt]?
Syntax
STATus:OPERation[:EVENt]? 
This query returns the value of the Operation Status Event register. The Event 
register is a read-only register, which stores (latches) all events that are passed by 
the Operation NTR and/or PTR filter. Reading the Operation Status Event register 
clears it. 
Remarks
– The following table lists the bit definitions for the Operation Status registers.
– Once a bit is set, it remains set until cleared by reading the event register or 
the clear status (*CLS) command.
For more information on the SCPI Status System, refer to Chapter 2, “Status 
system diagram” on page 21.
