3 Advanced Triggering, Search & Navigation, and Segmented Acquisition Labs

29 Press the [Acquire] front panel key.

30 Press the Segmented softkey; then turn the Entry knob to select 500 as

the number of segments to capture.

31 Press the Segmented softkey to begin a Segmented Memory acquisition.

32 Press the Current Segment softkey; then turn the Entry knob to review all

500 captured segments.

33 Set the Current Segment to 500 and note the time-tag of the last captured

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 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.

consecutive runt pulses.
