13.15.3.2 Triggering on Ethernet signals
Prerequisite: A bus is configured for the Ethernet signal to be analyzed.
For the basic trigger settings, proceed in the following way:
1.
Press the [Bus]
key and selet the "Shortcuts" tab.
2. Press "Setup trigger".
3. Tap the "Source" button and select the "Serial bus" trigger source.
4. Select the serial bus that is set to Ethernet.
5. Tap "Type" and select the trigger type to be used for Ethernet protocol analysis.
Available trigger types are "Frame Start", "Pattern", "Adv frame" and "Adv error".
6. Depending on the selected Ethernet variant, more setup conditions have to be
specified.
For information on how to proceed with the configuration settings, see Chap-
ter 13.15.3.1, "Ethernet trigger settings", on page 732.
13.15.4 Ethernet decode results
When the configuration of the serial bus is complete, the signal can be decoded:
1. In the "Protocol" dialog > "Setup" tab, enable "Decode".
2. In the "Protocol" dialog > "Display" tab, select additional result display settings:
"Show decode table" and "Show binary signals".
For a description of the display settings, see also Chapter 13.1.3, "Display",
on page 487.
The instrument captures and decodes the signal according to the standard definition
and the configuration settings.
The color-coding of the various protocol sections and errors simplifies the interpretation
of the visual display. The decode information condenses or expands, depending on the
horizontal scale. Various data formats are available to show the result values.
Decode Results Table
The results are shown in two tables:
●
"Decode results": contains information about all decoded frames
●
"Details frame": contains more detailed information about the selected frame in the
"Decode results" table.
