Serial Bus Decoding & Triggering, Search & Navigation, and Segmented Acquisition Labs
Figure 48 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 just bursts of data that include a parity error over a time- span
exceeding 11 seconds as shown in
Note that although not shown and demonstrated, we can also view the
segmented decoded RS232/UART serial data in the "lister" format, and we
can also perform Search & Navigation on the segments. Let's now view
this decoded RS232/UART in a different numeric format to uncover a
important Agilent marketing message.
