You can reset the accumulated average by pushing the Clear Sweeps button
on the front panel.
Normal mode
Average mode（32）
Note: Average acquisition is only valid for periodic signals, and it is important
to ensure that the waveform is triggering in a stable way when using average
mode.
Eres: Enhanced resolution mode. The oscilloscope filters the sample, which
rejects noise in the high frequency domain, so the signal-to-noise ratio (SNR)
is improved. As a result, the effective number of bits (ENOB) of the oscilloscope
is enhanced. For the SDS5000X, Eres processing is implemented by the
hardware engine, so it can still maintain a high waveform update rate when the
acquisition mode is average.
Normal mode
Eres mode (3-bit)
Eres acquisition does not require the signal to be periodic, nor does it require
