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

[Tom Wiltshire]

no, don't use X/Y mode. At least, I wouldn't.

I'd stick the staircase into one input and the VCO into the other,  
set to some easy-to-trigger-from waveform like a ramp or square, and  
then set the trig to the VCO channel. Then just set the timebase long  
enough that you can see a couple of wavecycles and you can compare  
the VCO output with the quantizer output.
