[sdiy] how to view a quantizer staircase on a scope?

i am a bit lost as i have never done any external triggering

here is what i think i should do

1, i connect the output of the quantizer to my vco input

2. i connect the square output of the vco into the channel 2 of my scope

3. i set trig mode to channel 2

4. i plug channel A of the scope INTO the output of the LFO i am driving the quantizer with (a saw wave)
