Rigol DS1054: freerun sweep

[OhhJustPeachy]

I'd like to use my Rigol DS1054 in a fashion that's better than a logic probe but worse than a logic analyzer by just setting the sweep frequency as near as I can to some integer dividend of the UUT's clock frequency and watching states flip around, i.e. with no trigger at all. I suppose I could hack this behavior by setting the time base mode to XY and feeding a sawtooth wave into the X channel and the probe into the Y channel but it seems like the scope ought to be able to do something like this on its own.

You could mess around with the "timeout" trigger.

Set it to minimum, turn the gain of one channel way up and trigger off the noise on that channel. That leaves you three channels to play with.

If you're going to do that then feed the sawtooth into a channel and trigger off it. That leaves you with three other channels.

I think the trigger channel can be hidden if it annoys you to see ti on screen.
