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

The bug described here has not been fixed yet, although it's been almost three months ...

amy, a lot of time has already passed, and you still have not fixed the problem indicated in this thread. More than two years have passed... Do I have to wait long?

amy, no, this bug has not yet been fixed. I checked it out. In addition, during the check, I found another bug. When changing the time scan in the direction of 20ns -> 8ns -> 4ns -> 2ns, there are no errors. But if you start to change the time scan in the other direction, you get the following: 2ns -> 8ns -> ... That is, there is no 4ns value.

I reproduce this problem. But I couldn't reproduce the last problem. 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...

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

Ok, I have reproduced.
The engineer will update the firmware next week.

The work week is over...

Please use this to update.
