Hello,

Unmounted acquisition board
Not much time to find the culprit.
Capacitor removed and board cleaned, no more short circuit.
I will replace it and make the change for acquisition at 2GB/s. I think it is necessary to put a resistance 0 ohm on r154 I think.
Under reservation that nothing else burn....

But it’s not clear yet.
It is R134 and not R154 (sorry)  that must be set to 0 Ohm
On the example R137 seems desoldered, on my board there are 0 Ohm, so the explanation is not clear.
Should we:
1st Delete R137
2nd Set 0 OHM to R134.
I’ll see later, because it’s accessible without the cover
