SDS6000A Series Digital Oscilloscope User Manual

Average: The oscilloscope accumulates multiple waveform frames and
calculates the average as the result. If a stable trigger is available, the resulting
average has a random noise component lower than that of a single-shot record.
The more frames that are accumulated, the lower the noise is. For the
SDS6000A, average processing is implemented by the hardware engine, so it
can still maintain a high waveform update rate when the acquisition mode is set
to average.
You can reset the accumulated average by pushing the Clear Sweeps button
on the front panel.
Normal mode
Average mode（128）
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.
Hi-Res: High-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 resolution of the oscilloscope is enhanced. For the
SDS6000A, Hi-Res processing is implemented by the hardware engine, so it
can still maintain a high waveform update rate when the acquisition mode is Hi-
Res.
