Adjustments
Digital filter with ability of setting the valid pulse length
up to 131072*Ts for each level and counter of valid
triggering events selectable from 1 to 32768 for each
level. HOLD-OFF selectable up to 1048576*Ts with
selectable AUTO mode, to sample proper amount of data
before trigger. (Ts – actual real time sampling period)
