*OPC
Syntax
*OPC
*OPC?
Description
Sets the OPC (bit 0, "Operation Complete") of the Standard Event register to 1 after all
commands are executed.
Queries whether all the previous commands are executed. The query returns 1 to the
output buffer after the command is executed.
Parameter
None.
Remarks
•
Operation complete means that all the previous commands including the *OPC
command have been executed.
•
When setting the instrument configuration through programming (by executing
the command string), using this command as the last command can determine
when the command queue is executed (when the command queue is executed,
the bit0 (OPC, "operation complete" bit) in the event register of the Standard
Event register will be set).
•
Sending the *OPC? command and reading the result can ensure synchronization.
