Serial Decode
Pressing [Single] instead of [Stop] fills the maximum memory depth.
When zoomed out and viewing a large number of packets, the Lister
may not be able to display information for all packets. However, when
you press the
[Single] key the Lister will contain all on- screen serial
decode information.
6 Press the Scroll Lister softkey and use the Entry knob to scroll through
the data.
Time tags in the Time column indicate the event time relative to the
trigger point by default, and can optionally be configured to be relative
to the previous row, as described in step 9 that follows. The time tags
of events that are shown in the waveform display area are displayed
with a dark background.

Press the
Zoom to Selection
softkey (or push the Entry knob) to center
the waveform display at the time associated with the selected Lister
row and automatically set the horizontal scale setting.
8 Press the Undo Zoom softkey to return to the horizontal scale and delay
settings before the last
Zoom to Selection
.
9
Press the
Options
softkey to open the Lister Options Menu. In this menu,
you can:
• Enable or disable the Track Time option. When enabled, as you select
different Lister rows (using the Entry knob while acquisitions are
stopped), the horizontal delay changes to the Time of the selected
row. Also, changing the horizontal delay will scroll the Lister.
• Press the Scroll Lister softkey and use the Entry knob to scroll though
data rows in the Lister display.
• Press the
Time Ref
softkey and use the Entry knob to select whether
the Time column in the Lister display shows times relative to the
trigger or relative to the previous packet row.
Searching Lister Data
When serial decode is enabled, you can use the [Search] key to find and
place marks on rows in the Lister.
The Search softkey lets you specify events to find. It is similar to
specifying protocol triggers.
