timebase or modify the memory depth.
The impact of low sample rate on the waveform:
1. Waveform Distortion: when the sample rate is too low, some waveform
details are lost, and the sample waveform displayed is rather different from the
actual waveform of the signal.
2. Waveform Aliasing: when the sample rate is twice lower than the actual
signal frequency (Nyquist Frequency), the frequency of the waveform rebuilt from
the sample data is smaller than the actual signal frequency.
3. Waveform Leakage: when the sample rate is too low, the waveform rebuilt
from the sample data does not reflect all the actual signal information.
