Figure 37 - Random noise averaged out
Eres (Enhanced Resolution)
Eres mode uses a digital filter to reduce the random noise on the input signal and generate
smoother waveforms. Eres can be used on both single-shot and repetitive signals and it does not
slow down the waveform update speed. Eres mode limits the oscilloscope's real-time bandwidth
because it acts like a low-pass filter.
