Roll Mode
Roll mode operates on time base settings of 50 ms/div or slower. This Roll
mode causes the waveform to move slowly across the screen from right to
left. In Roll mode, there is no trigger, that means no pre- trigger
information is available. A reference point is fixed on the right edge of the
screen and refer to the current moment in time.
The Roll mode is useful in low frequency waveform to yield a display in
much like a strip chart recorder that allows the waveform to roll across
the display.
