Chapter 4 Measurement Configuration Settings
Several utility functions can be applied when acquiring data.
Select from the [Utility Function] setting column on the Status Settings screen.
Make these settings before measuring.
This applies to the Memory function only.
When measuring at slow sampling rates with the Memory function, you normally
have to wait for recording to finish the specified recording length before viewing
the waveform. However, by using the Roll Mode, you can view the waveform as
the data is acquired. The new waveform scrolls automatically.

CURSOR
Move the cursor to the [Roll Mode] item.
F1 to F8
Enable or disable the function.
Off
Normal recording. Data is displayed only afte
r
acquiring the specified recording length.
On
Waveforms are displayed while recording
(with 1-ms and slower settings). When the
timebase is set to 500 µs/div or faster, wave
-
forms are not displayed until after acquisition
has finished.
Auto
Regardless of the timebase setting, whethe
r
or not the waveform is displayed depends on
the waveform display magnification settings
while the data is being recorded.
However, if the waveform display is set for a
faster timebase than 100 ms/div, it is only dis
-
played after acquisition has finished.
When [Auto] is selected
Example: When the timebase setting is 1
ms/div
If display magnification = [x 1], displays af-
ter the waveform has been recorded.
If display magnification = [x 1/100], dis-
plays while recording because the display
is 100 ms/div.
