Average. Use Average acquisition mode to reduce random or
uncorrelated noise in the signal you want to display. Data is acquired
in sample mode, then a number of waveforms are averaged together.
Select the number of acquisitions (4, 16, 64, or 128) to average for
the waveform.
Scan Mode Display. When the SEC/DIV control is set to 100 ms/div or
slower and the trigger mode set to Auto, the instrument enters the
scan acquisition mode. In this mode, the waveform display updates
from left to right. There is no horizontal position or trigger control of
waveforms during scan mode.
Stopping the Acquisition. While acquisition is running, the waveform
display is live. Stopping the acquisition freezes the display. In either
mode, the waveform display can be scaled or positioned with the
vertical and horizontal controls.
