Oscilloscope Question

--- Quote from: Brentd27 on September 19, 2019, 06:40:40 pm ---This is a bit of an "Am I doing this right?" question.
I have a Rigol DS1054 oscilloscope (with the 100Mhz firmware). I'm working on an arcade MPU that uses an MC6800 CPU. I'm wanting to test the reset delay between power on and when the reset line goes high.
I tried setting the scope to single shot, connecting channel one to the +5V power rail, and channel 2 to the reset line, then setting the trigger to activate when the channel 1 starts to go high. I get a capture, but it doesn't seem to show any delay between the two pulses, even zoomed in.
Is the delay beyond the resolution of my scope, or am I doing this wrong?

How will you see any difference if channel one is on the +5 rail already high...?
james_s:
Who said it's already high? I can only assume he's shutting the thing off, connecting it, then turning it on, so the scope will then trigger when the 5V rail comes up.
