I'm using a PicoScope 3205 to capture data wavefoms (amongst other things). One waveform is a burst of data about 10ms long followed by a 90ms gap. I've set the scope to repeat triggering and 2ms per division in the expectation that it will then trigger on the beginning of the burst of data. Much of the time it triggers as expected. However some of the time it misses the beginning of the data and triggers later in the data burst. If I pre-trigger, then it is clear that when the trigger is late it is not that the data has been missed - it's just that the trigger is late.
Any ideas for ways of avoiding this behaviour so that the trigger is more reliable?
Most conventional scopes have 'trigger holdoff' which helps resolve such triggering difficulties. Is there something similar available here?
