If as Martin says there is a 2k frame capability, you should have 1k frames each side of your trigger point capture.

Please explain to me, how i should trigger "on a missing frame"! It has no edges, it has no id nor data.   :-/O

We need more info.

Frame rate is tied to a Clock is it not ?
If missing and like this ----- ---- it should be easy to trigger on where the frame should be.
Once captured we can engage Decode to investigate.

I see you have 23 frames in ~0.2s. That would make 1150 frames for the whole buffer at 1s/div. You didnt had 2s/div, had you?

Yepp, 2s/div.

I guess you can see those undecoded frames on the right, when you scroll there? Let those others drop off on the left.

Martin72:
The list displayed on the screen can only be scrolled from top to bottom (and back), or what do you mean?

eTobey:
The horizontal axis.
