3. Width switch and the time division switch on your O Scope match There will come a point where the trigger is too fast for your eye to view it using an analog scope If you leave the time division at 500mS or 50mS you will be able to view faster pulses but it will be a very dim and quick dot and you will have to look closely to see it but once again verify the pulse by the counter It should go up 1 every time you push the button
