No, I'm measuring ONE waveform signal on O scope channel#1
CHANNEL#1 has ONE waveform signal
CHANNEL#2 has the 400hz sync signal , You "source" this to the trigger input ( there is a mode switch that say's SOURCE ) it's next to the add, chop, etc.
Audio amplifiers has a sync signal at 60hz, all the frequencys from 20hz to 20khz are sourced to a 60hz sync signal that comes out of the wall 120 VAC at 60hz
Why do you think they use 60hz out of the wall? because hum sounds nice and easy to filter? it's a sync signal , external sync signal
The frequencys don't have to be multiples in order to be synced
You can take a function generator and sweep it from 20hz to 20khz and get STABLE waveforms on the O-scope right? and all those frequency's from 20hz to 20Khz are sync to 60hz right?
