parity errors. We will then review the captured errors to determine how
often they occur. But to complete the rest of this lab your scope must be
licensed with the Segmented Memory option.
43 Press the [Acquire] front panel key.
44 Tap the Segmented softkey; then enter 50 on the keypad as the number
of segments to capture.
45 Tap the Segmented softkey to begin a Segmented Memory acquisition (be
patient… these errors occur very infrequently).
46 When the scope finishes capturing 50 segments, tap the Current Segment
softkey; then turn the Entry knob to review all 50 captured segments
and note the time between each event.
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 just bursts of data that include a parity error over a time- span
exceeding 20 seconds as shown in Figure 65.
