Hi pyrpl friend,

I am using your fantastic and working SDK for my project and can only use fast analog input configiration of +/-1V. But I need your urgent help to let me know how can I configure the input for +/-20V ??

Best regards, Pouya, Oslo

Hi, no problem in using the +-20V range, but the displayed voltage will remain between +-1V. Thus, to get the correct scope reading, you have to multipy the numbers by 20.
