ONOFF_ON – turns the digital shielding on

level – determines the digital shielding factor (valid values are: 2, 4, 8, 16, 32

and 64)

Return value: -

Remark:
In order to make the digital shielding work correctly, it is necessary to have a stable
and well triggered signal on the input. Digital shielding prolongs the oscilloscope
response to the signal change (the higher the factor the longer the response).
