ok, I'm assuming I'm doing something wrong here.
I have been using my scope to see the effects of decoupling capacitors in some simple switching circuits. I'm a noob paying my dues and this has been a great exercise.
The only thing that bugged me was that I was having to reposition my traces a lot after changing the vertical scale. I'm watching a 5v signal at 50mv/div and want to get into 10mv/div and then my position changes from -5v to something else and I have to wind the position knob to get it back to -5v.
It seems to me that the viewing window is pivoting around the 0v point which makes sense when you are viewing an AC curve or something like that but when you're studying something that is centered around another voltage it becomes a lot harder.
Is there something I can do to help this? Pivot around a cursor? or a reference mark perhaps?
Cheers,
Jase
