segment.
Segmented Memory optimizes oscilloscope acquisition memory by only
capturing important segments of a waveform based on the trigger
condition and timebase setting. In this example, we have selectively
captured over 700 ms of total acquisition time as shown in
Note that we can also view the decoded I

S data in the “lister” format,
and we can also perform Search & Navigation on the segments.
