The acquired waveforms are overwritten infinitely on the screen. This
is convenient to continuously observe changes of a signal.
If the state is changed from STOP to RUN by pressing the RUN/STOP
button, persistence operation is started and the screen is initialized when
the first captured waveform is displayed.
For the operation in persistence mode, see page 28. With persistence
ON, waveforms are displayed with dots irrespective of Join setting.
Measurement example of signal with modulated amplitude
The function and operation change depending on the memory length.
1 k (1024) words/channel
Waveforms are displayed depending on the Join setting in display menu.
100 k (102400) words/channel
In RUN state, waveform is always displayed in join irrespective of Join
setting.
In STOP state, waveforms are displayed depending on the Join setting.

Limitation on long memory
• Average or equivalent sampling is not available.
• The voltage value in automatic measurement or V at t measurement is displayed
in STOP state.
When PERSISTENCE is set to ON,
“S” is displayed reversely.
In this example, Burst of the Event
trigger is used for stable triggering.
Limitation on PERSISTENCE
In the roll mode, PERSISTENCE
is not performed.
