Figure 18 With Random Noise, Average Mode
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.
High Resolution mode can be used on both single- shot and repetitive signals and it does
not slow waveform update. This mode limits the oscilloscope's real- time bandwidth
because it effectively acts like a low- pass filter.
Note: “Average” and “High Res” modes use different averaging methods. The former uses
“Waveform Average” and the latter uses “Dot Average”.
