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.
A. Turn on or off sequence
B. Set the segment
Sequence mode is a fast acquisition mode, which divides the memory depth to
multiple segments (up to 90,000), 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.
