High Resolution
This mode uses a kind of ultra-sample technique to average the neighboring points
of the sample waveform to reduce the random noise on the input signal and generate
much smoother waveforms on the screen. This is generally used when the sample
rate of the digital converter is higher than the storage rate of the acquisition memory.
Note: "Average" and "High Res" modes use different averaging methods. The
former uses "Multi-sample Average" and the latter uses "Single Sample Average".
