Hi all,
Learning the ways of the oscilliscope, I am trying to capture the process of charging a capacitor with a long RC time constant (tau ~ 2 sec). I thought "single shot" would work great, but my scope never actually displays the waveform.
I have a Rigol 1000E series, and I followed the instructions in the manual (set the trigger threshold, use upward slope, etc). If I look at something on the scale of milliseconds like switch bounce, it captures the wave form great, so I think I am performing the setup more or less correctly.
Can anybody comment? Is it something with the scope capturing for a long period?
Interesting (to me): If I use the "rolling" view, I can watch my slow process and stop when I want to look at the waveform. Rolling is useless with quick things like switch bounce but maybe good for stuff like this.
