Antialiasing

At slower sweep speed, the sample rate is reduced and a dedicated display algorithm
is used to minimize the possibility of aliasing.
Press Acquire  Anti_Aliasing to enable or disable the antialiasing function. By
default, antialiasing is disabled. The displayed waveforms will be more susceptible to
aliasing when this function is disabled.
