Page 76 SDS2000X HD Series Digital Oscilloscope User Manual Average mode（128） Normal mode Note: Average acquisition is only valid for periodic signals, and it is important to ensure that the waveform is triggering stably when using average mode. ERES: In this mode, the oscilloscope digitally filters the sampling points, which can reduce the broadband random noise on the input signal and improve the signal-to-noise ratio, to improve the effective resolution (ENOB) of the oscilloscope.
