This applies to the Memory function only.
Displayed waveforms are retained on-screen and overlaid with new waveforms.
• Use this to compare new waveforms with those recorded immediately before.
(When the trigger mode is [Repeat] or [Auto]) ( p.153)
• There are two overlay methods: automatic overlay during measurement and
manual overlay.
8.3 Displaying New Waveforms Over Past
Waveforms (Overlay)
Normal Display
Waveforms with the Overlay Function
Procedure
To open the screen: Press the STATUS key → [Status] sheet
Move the cursor to the [Overlay] item.
Select
Off Overlay disabled.(default setting)

 p.125)
This mode cannot be used simultaneously
with the Roll Mode.
"When the Overlay function is enabled

To open the screen: Press the DISP key →Waveform screen
Move the cursor to the [Overlay].
Select
Overlay
(F1 key)
Pressing F1 key [Overlay] leaves the loaded waveform on
