Lesenswert?

Greeting and thanks to all hard working software and hardware developers 
working on Welece open source project!
Sorry for writing in english, but my german is very very bad:)

I have a few question, and maybe someone can try to help me out on the 
answers. I did go trough all hw and sw threads here, but maybe google 
translate missed something...

1. Walter's piggyback board with LMH6518.
How much noise reduction we can expect with this frontend? If I read 
correctly Walter's notes, it should be by about factor of 4.

2. Trigger issue
If I try to take a single shot, for example at 2 V/div, trigger level 
set below 3-4V will automaticaly trigger on something? Same thing 
happens on all other ranges, it takes minimum of 1 division of trigger 
level to be able to take single shot correctly. Is this normal?

3. Does anyone have an estimate on how many waveforms/s Welec can 
display with latest BF versions of firmware?

Once again, all the best to all working on this project!
