Description: Generates the OPC message in the standard event status register when all pending overlapped operations have been
completed.
Parameters: none
Response: none
Example: *OPC
Command: *OPC?
Syntax: *OPC?
Description: The OPeration Complete query *OPC? parses all program message units in the input queue, sets the operation complete bit
in the Standard Event Status register, and places an ASCII ’1’ in the output queue, when the contents of the input queue
have been processed.
Taking advantage of this feature, and using *OPC? in a loop to query until the instrument returns 1, can lead to useful gains
in program execution efficiency.
