Press the [Run/Stop] front panel to begin repetitive acquisition again.
47
Press the [Acquire] front panel key.
48
Press the Segmented softkey; then turn the Entry knob to select 500 as
the number of segments to capture.
49 Press the
Segmented
softkey to begin a Segmented Memory acquisition.
50 Press the
Current Segment
softkey; then turn the Entry knob to review all
500 captured segments.
51
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 over 4 seconds of total acquisition time as shown in
Figure 59 .
Note that we can also view the decoded SPI data in the “lister” format,
and we can also perform Search & Navigation on the segments.

SPI traffic.
