I've been using roll+high res as an approximation of a DMM trend plot, so I'm not after much in the way of bandwidth, hehe.

- not sure why the DSOs don't look a little better?

I added 1 more with the DS1104Z cranked up on the intensity to 71%; maybe better?
---
also added 1 more showing DS2000 being fed by function generator with signal slightly less modulated; there is a point at which as more modulation is added the waveform becomes visibly more "striated" (and less striated as modulate is decreased)

If you look at the DS1000 first rise of the modulated signal compare to the DS2000 you will notice that the higher sample rate of DS2000 is capture more information from the signal. Therefore the intensity grading of both waveforms can't be compare equally.

That's the problem with trying to compare intensity-grading between DSOs. Ideally, you'd compare images when they are capturing at similar wfrm/s rates.

EV:
Rigol seems to advertise lower over shoot for DS2000A. There is however no measurement. Maybe it looks lower. Look at pictures. For DS2000 it is about 8 % measured by my scope.


--- Quote from: EV on December 02, 2013, 09:10:48 am ---Maybe, I don't know. The over shoot with Rigot is also quite big. It should be under 3 %. Maybe the adaption with 50 Ohm feed through terminator is not very good.

Because the analog scope intensity is infinitely variable, while the DSOs are quantized.  And they burn up some of those levels in the Brightness bias.

In spite of that limitation, I'd say they look pretty good.  Certainly better than my old DS1102CD.
