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 an Ultra Segmentation acquisition
series. Thus, you can acquire exactly one Ultra Segmentation acquisition series with
RUN N×SINGLE.
If Ultra 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 37.
●
It is the "Finished" criteria for the state of a mask test.

Mode ← Arithmetic
Waveform arithmetics build the resulting waveform from several consecutive acquisitions
and subsequent math calculations of the signal. For details see "Wfm Arith-
metic" on page 34.
"Original"
The original results are displayed
"Envelope"
The envelope curve of all acquired and calculated results is displayed
"Average"
The average of all acquired and calculated results is displayed
SCPI command:

Reset mode ← Arithmetic
Defines when the envelope and average evaluation restarts.
"None"
No restart, the number of acquisitions considered by the waveform
arithmetics is not limited.
"Time"
Restarts the envelope and average calculation after the time defined in
"Reset time".
"Waveforms"
Restarts the envelope and average calculation after a number of
acquired waveforms defined in "Reset count".
