11.2.4 Roll Mode
Click Acquire > Roll 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, click Acquire > Run/Stop . To clear the display
and restart an acquisition in Roll mode, perform Acquire > Run/Stop again.
Note:
Zoom is only supported after Stop in Roll mode.
11.2.5 Sequence
Click Acquire > Sequence to recall the 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 into multiple segments
(up to 80,000), each of which stores a single shot. In sequence mode, the oscilloscope only acquires
and stores data without processing and displaying it 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 SDS6000L can achieve a minimum 1.3 us trigger interval in Sequence mode,
corresponding to a waveform update rate of 750,000 wfm/s.
After the acquisition is finished, the oscilloscope will map all the segments together to the screen. If
you need to view and analyze each frame separately, history mode will help (see the section "History"
for details). History mode provides timestamp labels for each segment.
