X speed about 5ms/div. With the trigger on AUTO set the trigger LEVEL mid-way between the high and low trace levels of the signal, then switch the trigger to NORMAL. Every switch change will show a capture, if it's bouncing. --- Quote from: vk6zgo on April 06, 2019, 01:00:12 pm ---Wouldn't "roll" do this on a DSO----it seems to have no other use! --- End quote --- I think it's very useful for slow changing signals, you get to choose when to press STOP by eye. |
