14.2.3 Roll Mode
Press the Roll button on the front panel to enter roll mode. In this mode, the
waveform moves across the screen from right to left, similar to a strip chart
recorder. The horizontal delay control of the waveform will be disabled when
roll mode is active. It only operates at timebase values of 50 ms/div and above.
If you would like to stop the display in Roll mode, press the Run/Stop button.
To clear the display and restart an acquisition in Roll mode, press the Run/Stop
button again.
14.2.4 Sequence
Touch Acquire > Sequence to recall sequence dialog box.

Sequence mode is a fast acquisition mode, which divides the memory depth to
multiple segments (up to 100,000), each of which stores a single shot. In
sequence mode the oscilloscope only acquires and stores data without
processing and displaying, until the specified segments are acquired. As a
result, the dead time between trigger events is minimized, thus greatly
improving the waveform update rate. If sequence mode is enabled, the display
will not update until all of the sequences have been acquired. The SDS5000X
can achieve a minimum 2 us trigger interval in Sequence mode, corresponding
