The acquisition and average count has several effects:
●
It sets the number of waveforms acquired with [RUN N× SINGLE]
●
It defines the number of waveforms used to calculate the average waveform.
Thus, the instrument acquires sufficient waveforms to calculate the correct average
if "Average" is enabled for waveform arithmetic. The higher the value is, the better
the noise is reduced.
●
It sets the number of acquisitions to be acquired in a fast segmentation acquisition
series. Thus, you can acquire exactly one fast segmentation acquisition series with
[RUN N× SINGLE].
If fast segmentation is enabled and configured to acquire the maximum number of
acquisitions, the acquisition count is set to that maximum number and cannot be
changed.
See also: "Number of acquisitions" on page 184.

It is the "Finished" criteria for the state of a mask test.

5.2.3 Fast segmentation
In normal acquisition mode, only a short time is used for sampling; processing and dis-
play take most of the time. The processing and display time is blind time causing a gap
in the recorded signal. The normal acquisition mode may miss very short-time and
infrequent events occurring during the dead time.
Figure 5-5: Normal acquisition with blind time
With fast segmentation, several triggered acquisitions are captured fast, with hardly
any dead time between the acquisitions. The data is processed and the waveforms are
displayed when the acquisition of the series has been completed.
