Stop Acquisition
When acquisition is stopped, the last acquired waveform is displayed. The
waveform can be moved by using the vertical and horizontal controls. When
the horizontal scale is set to 20 ns or faster, the oscilloscope uses sine(x)/x
interpolation to expand the horizontal signal resolution.
Equivalent Time Sampling
The equivalent time sampling mode can achieve up to 20 ps of horizontal
resolution (equivalent to 50 GSa/s). This mode is good for observing repetitive
waveforms and should not be used for single-shot events or pulse waveforms.
Average Acquisition
The Average Acquisition mode should be used to remove random noise from
the waveform and to improve measurement accuracy. See Figure 2-23 and
Figure 2-24. The averaged waveform is a running average over a specified
number of acquisitions from 2 to 256.
