How would this help? OK, if I had a let's say 50Hz and 100Hz signal I would create my own horizontal axes.
Is it normal, when I put the timebase to 1s/div or slower, I would expect to see a slow line from left to right, to see the signal and it's history. For example, 0V from the source. I put it to 1s/div, the first 10s I don't see anything, it's very laggy, then the whole line is at 0V. I turn the source up to 10V, I still can see 0V, 10s later POW 10V. Sometimes I don't even see the point when the source was turned up.
