There are two possible solutions:
- You can set the File scope to be signal triggered, and only activate the trigger signal when you want it to actually trigger. This will then capture data for a short burst (= Number of Samples in the file scope) following each trigger. Note that the triggering only "takes" after the Number of samples have been captured
- Put the scope block into an enabled subsystem and feed the enable port with something that controls your logging. The scope will log for exactly those samples that the enable input is true. You should keep the scope's triggering as "Freerun" for this case.
