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 500 occurrences of positive
and negative runts of any width for a total acquisition time of more than 20 ms as
shown in
Figure 40
Using the scope’s Segmented Memory acquisition to selectively capture 500
consecutive runt pulses.
