ROLL mode
The displayed waveform is rolled from right to left (0.2s/DIV to 100s/DIV).
The right end of each trace is the updating point of a new data. The Roll mode
facilitates the measurement of a signal of approximately 100Hz or lower. Press
the STOP switch to stop the ROLL mode and hold the final waveform on the
CRT.

NOTE:
Aliasing:
While measuring the signal in such STORAGE mode as SMPL, AVG, etc., the
aliasing can be occurred by inputting a signal of more than half of the
frequency with respect to the sample clock frequency at the sweeping range is
added.
When the aliasing is occurred, the waveform of the input signal frequency
minus the sample clock frequency will be displayed. It is possible that this
display is judged a current waveform. If the aliasing is suspected, select the
REAL TIME mode and check if the display is the same as that in the actual
operation mode.
