Roll (Roll) - Iwatsu DS-8814 Operation Manual

Roll (ROLL)

Roll print
Roll print
format
Outputs readout. Roll print is possible
while the sweep time is slower than 5 s/div.
Pressing RUN/STOP shows a frame
and stops operation.
Restrictions in roll mode
• Averaging and persistence are not executed.
• Automatic measurement results, Math (calculated) waveforms and XY are
displayed in a Stop state.
• Turning On the Auto Copy or Auto Save function automatically sets Roll to
Off.
• On the contrary, turning On Roll automatically sets the Auto Copy or Auto
Save function to Off.
The acquired waveform is displayed in real time. Available sweep
range is 100ms to 50s in Short memory length, 2s to 50s in Long
memory length.
When operating at slower sweep rate with roll mode off, the
waveform is displayed on the screen after all waveform data has
been captured up to the specified memory length, and so it is not
possible to observe the phenomenon in real time.
A roll operation performs acquisition and displaying of waveform
data on the screen simultaneously like a recorder, making it possible
to observe changes in the waveform in real time.
Outputs waveforms to a built-in printer simultaneously.
Roll print is performed by pressing the Copy button, while the
sweep time is 5, 10, 20 and 50 s/div in the roll mode.
(Set Device to Printer and set Source to Screen in the Copy menu
of UTILITIES beforehand.)
While roll print is in progress, no operation is possible other than RUN/
STOP button operation.
To stop roll print operation, press the RUN/STOP button.
While roll print is in progress, the waveform is continuously output
as a recorder image as shown in the figure below.
