4 Serial Bus Decoding & Triggering, Search & Navigation, and Segmented Acquisition Labs

46 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.
