Use buffer mode.
Trigger can only be set within hardware memory depth.

Thanks for your reply, I already used buffer mode, it always move the trigger position. As attached.
What should I pay attention ?

Under buffer mode, you can set the trigger position, and then restart your capture.

Hi, I am having the same issue with my DSLogic device.

Is there a workaround for that?
Thx

I have the same issue with older SW-version as well as after update to V1.1.2. for hardware DSLogicBasic.
Inspite of buffer mode and placing trigger position greater than 1 %, the trigger does not move.
I desperatly look for a hint / solution.

The trigger position will be at the setting position only when trigger event happend after setting position.
For example, if the first sample hit the trigger, the trigger position must be 0, because there are no any samples before the first sample.

I see, that makes sense. Many thanks for replying it.

I have a similar issue here with version 1.2.0 built from today's (July 18, 2022) git. I can set the trigger to about 30% but that's it. I really need 99% to capture the issue I'm trying to debug.

My guess is that this is a GUI scrolling issue.

You use RLE compression.
Trigger postion can only be set within hardware memory depth.
If you need 99%, please unselect RLE mode.

@DreamSourceLab Thanks for the explanation and great product ! It's a life saver.

The issue still persists also in newest gui version. Independent of the recommendations the trigger position is not stable and jumps around.
