Rigol DS1054z excessive vertical scrolling
« on: December 11, 2015, 10:47:24 am »
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

Set the channel coupling to AC.

Excellent!  Thank you very much.  Time to RTFM a bit more I think.

I seem to remember that on the older series of scope you could select that the scop zoom on the 0V line or the trace itself. Not sure if this model will do that too.

Yes. Go to Utility -> System -> VerticalRef. and select "Center" or "Ground".

Center: when the vertical scale is changed, the waveform will be expanded or compressed around the screen center.

Ground: when the vertical scale is changed, the waveform will be expanded or compressed around the signal ground level position.
