Note: “Average” and “ERES” mode use different averaging methods. The
former uses “Waveform Average” and the latter uses “Dot Average”.
ERES
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. ERES mode is generally
used when the sample rate of the digital converter is higher than the storage rate
of the acquisition memory.
ERES mode can be used on single-shot and repetitive signals and does not slow
waveform updates. This mode limits the oscilloscope's real- time bandwidth
because it effectively acts like a low- pass filter.
