*OPC
Syntax *OPC
Description After you run the command, Bit 0 (operation complete bit) in the event register part of the
standard event status register is set to 1.
Queries whether the *OPC command has been executed. If yes, it returns "1" in the output
Remarks "Operation complete" indicates that all pending operations were completed following
the execution of the *OPC command.
Sending the query command *OPC? and reading the results can ensure that all the
commands can be executed one by one.
When configuring the instrument by programming commands (executing a series of
command), running the command as the last one can determine when the command
queue can all be executed. After all the commands in a queue have been executed,
Bit 0 (OPC, operation complete bit) in the event register part of the standard event
status register will be set to 1.
If you first run the query command (querying data of the output buffer) and then
send the *OPC command, you can determine when the data is available through the
Return
Returns 1.
Example

*OPT?
