Sequence
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, improving the waveform update
rate.
If sequence mode is enabled, the display will not update until all of the sequences have been acquired. The 2560B series
can achieve a minimum 2 s trigger interval in sequence mode, corresponding to a waveform update rate of 500,000
wfms/s.
Sequence mode can capture and record rare events over long time periods. The oscilloscope can capture multiple events
that satisfy the trigger conditions, ignoring the periods of no interest between adjacent events, maximizing the use of
waveform memory. Full accuracy of the acquisition timebase can be used to measure selected segments.
After the acquisition is finished, the oscilloscope will map all the segments together to the screen. To view and analyze
each frame separately, use history mode (see the section " History" for details). History mode provides timestamp labels
for each segment.
