Serial Decode
Before you can select a row or navigate through the Lister data, oscilloscope
acquisitions must be stopped.
5 Press the [Single] key (in the Run Control group on the front panel) to stop the
acquisition.
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.
7 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.
