*OPC?
Description After executing this command, the bit0 (OPC, "operation complete" bit) in the event
register of the standard event register is set.
Query whether the *OPC command is executed. The query returns "1" to the output
buffer when the command is executed.
Explanation  Operation complete refers to that all the previous commands including the
*OPC command are executed.
 Sending the *OPC? command and viewing the result can ensure
synchronization.
 When setting the instrument configuration via 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).
 Send the *OPC command after sending command to load the information in
the output buffer (query data) of the power supply and you can determine
when the information is available via the "OPC" bit.
Return Format The query returns 1 when the current operation is completed.
Example *OPC /*Set the bit0 (OPC, "operation complete" bit) in the event register of the
standard event register after completing the current operation*/
*OPC? /*Query whether the current operation is completed and the query
returns 1*/
