The trigger is set to fire when the signal enters the top window, but the signal never enters the top window. 

The icon for the trigger kind of indicates that the point is a transition between "middle" and "not middle" areas, and then you configure which transitions are interesting (middle-top, middle-bottom, or both; etc.)

And yes, based on our current understanding of the trigger, a "top" trigger does nothing with the lower trigger threshold.

I'm not sure there's anything clear about Rigol's legends and names for this (and some other) triggers ;D  They also seem to have skimped on storage space for the different trigger icons used at the top, which rarely change due to conditions you set for the trigger (they only change for Edge, Pulse, and Slope).

The icon you posted stays the same regardless of conditions. And the delta icon and level doesn't make sense if you think of the area as 2 windows. They only use it because they don't devote enough screen real estate for two distinct voltage levels.

I wrote software for displaying extended trigger information in RUU because, for the complex triggers, the amount of info Rigol displays is pathetic. Take a look at one of my screen images posted from RUU (with Trigger Level indicators turned ON) and decide if it or the DSO provides better insight into what the Windows trigger is doing ;)

Aww, such a missed opportunity! Firmware update suggestion :)  Ok, I'll redact my post.

Absolutely! If they just got creative with their icons at the top, they could provide a lot more information than they do ;)

--- Quote from: Pasky on January 16, 2014, 03:30:31 pm ---Question on the usage of the DS2072.  I've found one thing extremely annoying issue, but perhaps there's a course/fine setting for the position knob that I'm unaware of.  When changing the vertical scale on the channel, I find it extremely annoying turning the position knob to find my signal again.  When I want to look at a 5V dc signal, and have it set to 50mV, I find myself turning the vertical positioning knob for what seems like forever.  Is there any way to do this faster?  I know you can press the knob button to get to 0V, but even that can take forever going from 0V to 5V in such tiny increments.  Thanks.

@Pasky: While thinking back on your question, it dawned on me that I didn't think to ask you exactly what you're trying to do. Forgive me if the following is obvious to you, but if you're looking for disturbances in a 5V DC signal, using AC coupling will center the signal at 0V (screen center) but also pass glitches and other disturbances you can zoom in on. If you're trying to "zoom in" on the upper edge of a 0 to 5V waveform, it's not going to work because you're going to overdrive the input amp - and whatever edge you see will end up being distorted anyway.

Oh sorry, that was just an example off the top of my head to, I'm not really doing anything in particular, I just found it extremely annoying to zoom in on any wave form in the lower mV divisions.

Also thanks that VerticalEx setting did the trick
