Hantek DSO5202BM: A bug that appears when you scroll the waveform horizontally

Oleg10011001

When the oscillogram is scrolled horizontally (no matter in which direction), the oscillogram is erroneously shifted relative to the triggering point of the trigger. The bug appears only when the "Time / Div" setting is set to "Fine" in the "HORIZ MENU" and then the time sweep is changed (in my case, I reduced the time from 8 ns to 5.04 ns). For example, here is a screenshot of the screen made before I started scrolling horizontally with "HORIZONTAL POSITION":




After scrolling the oscillogram horizontally, the oscillogram shifts relative to the triggering point, which can be seen on the following two screenshots:

amy, I don’t understand why you can’t reproduce this bug ... I get it stably if I follow the instructions that I gave in my first message in this thread. Here is a short video demonstrating this bug: https://youtu.be/7etwLMoFtYY

Just turn on the oscilloscope. Then set the time scan to 2ns. After that, try increasing this value  ...

Наверное лучше им отправить видео.

Yes, I have reproduced this problem.
You said the last bug has not beed fixed. But I couldn't reproduce. Please describe the procedure.

Just turn on the oscilloscope. Then set the time scan to 2ns. After that, try increasing this value to 4ns. I have at this step stably instead of 4 ns the value is set to 8 ns...

I reproduce this problem. But I couldn't reproduce the last problem. Please describe the procedure.
