Triggering on D-PHY
Prerequisite: A bus is configured for the D-PHY 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. Tap "Serial bus" and select the serial bus that is set to D-PHY.
5. Select the "Trigger Type" to be used for D-PHY protocol analysis.
6. To refine the trigger settings, configure additional settings, which are available for
some trigger types.
For details, see
Chapter 13.23.3.1, "D-PHY trigger settings"

D-PHY decode results
When the configuration of the serial bus is complete, the signal can be decoded:
1. In the "Serial Bus" dialog > "Setup" tab, enable "Decode".
2. In the "Serial Bus" dialog > "Display" tab, select additional result display settings:
"Show table" and "Show binary".
3. If required, enable "Zoom coupling"
For a description of the display settings, see also
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.
If a frame is marked red, some kind of error occurred. To analyze the error, see the
indication of the corresponding frame in the result table.
ECC checks are supported. ECC can correct a certain number of bit errors in the
header. If the errors can be fixed, the status is an ECC warning. If there are too many
errors, an ECC error is shown.
