on page 290.
To order protocol triggering and decode licenses, go to www.keysight.com and

contact your local Keysight Technologies representative (see
www.keysight.com/find/contactus).
Protocol Listing
The Protocol Listing window is a powerful tool for investigating protocol failures.
You can use the Protocol Listing window to view large amounts of packet level
serial data in a tabular format, including time tags and specific decoded values.
To use the Protocol Listing window:
1 Set up trigger and decode on the serial data signals to be analyzed.
2 Press [Protocol Decode].
3 In the Protocol Decode dialog box, select the Protocol Listing tab.
4 In the Protocol Listing tab, select On.
When multiple protocol decodes are enabled, the Show option selects the one
displayed in the Protocol Listing window.
In the Protocol Listing tab, you can also:
• Enable or disable the Track Time option. When enabled, as you select
different Lister rows, the horizontal delay changes to the Time of the
selected row. Also, changing the horizontal delay will scroll the Lister.
• Use the Time Ref drop-down list to select whether the Time column in the
Lister display shows times relative to the Trigger or relative to the Previous
Row.
5 Before you can select a row or navigate through the Protocol Listing data,
oscilloscope acquisitions must be stopped.
Press the [Single] key to stop the acquisition.
Pressing [Single] instead of [Stop] fills the maximum memory depth.
