Hi
Well â¦..
You can bash both ATâs and SCâs a *lot* harder than you might think. Both
will suffer quite a bit in terms of ADEV when you do.
Since the AT likely has a lower resistance (by quite a bit) than the SC, the loop
current ( and thus the drive into the buffer) may not be as far different on the
two as you would guess.
