Came across these issues mentioned on the web and i was able to repeat them in my DSOx2004A Scope.
What is the cause of these problem?
Dynamic Range issue ?

waveform display or Trigger jitter?

In the first video he is overdriving the pre-amplifier, and it is rining. This is 100% normal. There are many techniques to avoid this, depending on what you need to do.

the second video is due to:
1. at 2 ms/div, 1 ch on, the max sample rate is 2.5 MSa/s, which is needed to capture the whole 10 ms. The 2000X does not have super deep memory, but it is deeper than any other scope at this price point. Deep memory gives you 2 benefits: 1) the ability to capture more time at a given sampel rate and 2) the ability to sample faster for longer. The 2000X's big brother, 3000X, will sample this at 100 MSa/s, and you won't see nearly as much wander. Can any other scope at this price point do even this well? I do not believe so.
2. our proprietary anti-alias sample algoritm. that edge is undersampled at 2.5 MSa/s, and the anti alias algorithm causes that wander.
Using the SNIGLE trigger for this will double the sample rate.
If you are considering one of these scopes, please contact your local supprot center, and they will show yout he rigth way to use these.
