I have a Rigol DS1074Z and can't figure out how to lower the time the scope spends pre-sampling to open up more memory for the actual data I want to see.
Here is a nice image that will hopefully explain better:
And here is what it looks like when I am trying to store beginning of USB communication:
Unfortunately almost 50% of the 12 million data points are wasted. I would like to move the TriggerPoint in the first image closer to the beginning. In other words, I really only need to see what happens after the trigger triggers (any maybe a little bit before)
Is there a setting I missed? Can this be achieved?
