I have HANTEK 6022BE, and I'm monitoring tree signal using it,
- FS (Frame sync clock)
- Pulse
- Transfer complete I'm using two channel of scope to monitor pair of these.
The problem is when I'm looking at signal 1 and 2 I can see here: (The yellow is 2 and blue is 1.)
In looking at 2 and 3 (yello is pulse and blue is TC):
Magically one pulse of signal 2 (pulse) has been vanished! But why? Generally looking at pulse alonely will causes neglecting one pulse. But only by signal FS all 6 pulse will be visible. How this can be!!

The problem was the transient you can see in the first picture, the blue one. When I connect the scope to it, it becomes stablize. Otherwize it is noisy and because of this other signal changes.
