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!
