averaged mode trace with other time correlated waveforms, bring those other
waveforms into the display of the channel that is setup for average mode.
Accumulate mode
In Accumulate mode, the oscilloscope accumulates all waveform acquisitions
and displays them on the screen without erasing the previously acquired
waveforms. This is similar to infinite persistence on an analog storage
oscilloscope. These acquisitions will stay on the display until Mode is
changed, or until the waveform is adjusted by a control that causes the
display to change, such as s/Div, Delay, or Connect Dots from On to Off.
When in Accumulate mode, the operation of the display grid follows special
rules when turned on or off (refer to the Grid Field paragraph later in this
chapter).
Connect Dots field
The oscilloscope display can be enhanced to show a better picture of a
waveform by using the Connect Dots On / Off. The default setting for the
Connect Dots field is Off.
If an edge is fast enough (relative to the sample rate), the signal may begin to
look like dots scattered around the display, because each sample is displayed
as a single dot. To give you a better idea of what the waveform looks like, the
oscilloscope can connect the sample dots together. Selecting the Connect
Dots field toggles the field between On and Off.

Grid field

The oscilloscope display can be set to Grid On or Grid Off. Selecting the Grid
field toggles the field between On and Off. In either Normal or Average
modes, the grid can be turned On or Off when the oscilloscope is not
currently running and the change appears on screen immediately. If the
oscilloscope is currently acquiring data, the grid will be drawn or removed
when the acquisition is completed. In Accumulate mode, the grid can be
turned On or Off at any time, but it will not be changed until the next
acquisition is completed or some change is made to the display screen that
causes the display to be erased and redrawn, such as changing s/Div.
