Query OPC status in the event status register
If you activate a time-consuming operation and wait for completion with *OPC?, a time-
out could occur before the operation is finished and you do not receive the returned
“1”. In addition, the test program is blocked while waiting with *OPC?. It is not possible
to process other (not interdependent) commands in the meantime or to communicate
with other instruments.
Thus, for time-consuming operations, you can avoid blocking the communication by
sending the operation complete command *OPC:
*CLS
*OPC
Afterwards you can poll the operation complete status in the event status register with
*ESR?.
This query returns the content of the event status register and afterwards clears the
content. See also Chapter 16.5.3.2, "Event status register (ESR) and event status
enable register (ESE)", on page 391.
