В осциллографе Hantek DSO5202BM похожая ситуация при синхронизации по переднему фронту импульса, а вот синхронизация по заднему фронту более-менее нормальная, хотя небольшой сдвиг тоже присутствует.

На моем осциллографе (Hantek DSO5202BM) данная проблема особенно ярко проявляется в режиме синхронизации по восходящему фронту импульса. По мере перемещения осциллограммы по экрану с низу вверх реальная точка срабатывания триггера на осциллограмме смещается от 0 ns до -400 ns:











А вот в режиме синхронизации по нисходящему фронту ошибочное смещение точки срабатывания триггера на осциллограмме, при изменении позиции осциллограммы на экране по вертикали, гораздо меньше, но оно все равно есть:

Somehow somehow this topic died out and it seems that the support service did not understand what the problem raised here is. I will revive the topic and give here another screenshot taken from the oscilloscope screen, in which I clearly showed how the problem manifests itself. Here's this screenshot:



In the screenshot, I have drawn with red lines the location of the trigger on the screen and the trigger trigger level, and put a blue dot on their crosshairs. On the waveform trace, at the trigger point, I put a pink dot. In principle, the point on the oscillogram marked in pink should be in the same place where the blue point is, however, as you can see, they are in different places on the screen and the distance between these points changes when you move the location of the oscillogram from bottom to top on the screen using control element "VERTICAL POSITION".
