13.17.5.3 Searching USBPD data
Prerequisite: A serial bus is configured for the USBPD signal to be decoded and ana-
lyzed.
To be able to search for a USBPD data, the "Show decode detail" field in the "Configu-
ration" tab of the protocol setup should be disabled. If "Show decode detail" is enabled,
the "Enable" search button is disabled.
The search for events is set up in the following way:
1. Press [SEARCH] or tap "Search" > "Setup" in the menu bar.
2. If the dialog box does not contain a search entry, tap the "Add" icon to create one,
as described in "To create a user-defined search" on page 460.
3. Tap "Source" and select the serial bus that is set to USBPD (e.g. "SerBus1", unless
already selected).
The search dialog for USBPD protocol analysis is opened.
4. Specify search criteria according to Chapter 13.17.5.1, "USBPD search setup",
on page 859.
5. To acquire a waveform, press [RUN N× SINGLE].
The R&S RTE performs a USBPD decode according to the thresholds and protocol
settings of the associated serial bus source (here in our example SB1).
6. To start searching the acquired waveform for specific events, tap "Enable" in the
search setup dialog:
The R&S RTE displays the "Search Results" box that lists the detected events.
For information on how to configure the search results presentation and how to navi-
gate the search results, see also "To display search zoom windows" on page 466 and
"Navigating search results" on page 447.
