This section lists commands and queries that begin with the letter O.
*OPC
Generates the operation complete message in the Standard Event Status Register
(SESR) when all pending commands that generate an OPC message are
complete. The *OPC? query places the ASCII character "1" into the output queue
when all such OPC commands are complete. The *OPC? response is not
available to read until all pending operations finish.
The *OPC command allows you to synchronize the operation of the instrument
with your application program. See Synchronization Methods on page 282.
