Figure 28 Using the scope's Segmented Memory acquisition to selectively capture 25
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 25 consecutive occurrences of this glitch for a total acquisition
time of than 78 ms as shown in
valuable acquisition memory capturing signal idle time between each
glitch. But the scope does provide us with timing information about the
time of each segment relative to the first captured segment. As you were
reviewing each captured segment, you should have determined that the
glitch occurs every 3.27 milliseconds.
