Enable OPC-bit
SEND:
*ESE 1
Start scenario. *OPC will set the operation complete bit in the status register when the start of
scenario is done and it is running.
SEND:
SOURce:SCENario:CONTrol start;*OPC
Wait 5s for the scenario to start. Then read the event status register.
SEND:
*ESR?
Check the Operation complete bit (0) in the result. If it is true, the start of scenario is completed
and you can ask for example the current position.
SEND:
SOURce:SCENario:LOG?
Then read the event status register to reset it:
SEND:
*ESR?

Operation Complete Query
The Operation Complete query places an ASCII character 1 into the device’s Output Queue
when all pending device operations have been finished.
When a scenario is running there will be a pending operation set that is released at the start of
each 100 ms epoch. As a consequence of this, an
*OPC?
command will constantly block
except for a short period at the start of each 100 msec epoch. The
OPC?
command (and
*WAI
command) can hence be used to synchronize the execution of other SCPI commands with
GSG’s internal processing loop, with a resolution of 100 ms.
The
OPC?
is the recommended method to synchronize commands as
*OPC?
blocks at the
user’s application, rather than within the GSG. The use of
*OPC?
over
*WAI
is to be
