3. 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 463.
4. Tap "Source" and select the serial bus that is set to 100BASE-T1 (e.g. "SB1",
unless already selected).
The search dialog for 100BASE-T1 protocol analysis opens.
5. Specify search criteria according to Chapter 13.10.5, "Search on decoded
100BASE-T1 data", on page 655.
6. To acquire a waveform, press [Single].
The R&S RTP performs an 100BASE-T1 decode according to the thresholds and
protocol settings of the associated serial bus source (here in our example SB1).
7. To start searching the acquired waveform for specific events, tap "Enable" in the
search setup dialog.
The R&S RTP 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 470.
13.11 Ethernet 1000BASE-T1 (option R&S RTP-K58)
1000BASE-T1 is a single pair Ethernet based protocol specialized for the needs of the
automotive industry, such as in the automotive networking applications, enabling
advanced safety, comfort and infotainment features within the automobile. Its specifica-
tions is reference to IEEE P802.3bp.

13.11.1 1000BASE-T1 basics
The 1000BASE-T1 has the following objectives:
●
Provides a PHY that supports full duplex operating at 1000 Mbps over a pair of
unshielded sheathed twisted-pair cable or better cable.
●
Achieves bit error rate (BER) of less than 1e
-10
.
●
Support for up to at least 15 meters of cable length in the automotive link segment.
To achieve the above objectives, 1000BASE-T1 uses Physical Coding Sublayer (PCS)
and Physical Medium Attachment (PMA) sublayer as follows:
●
Adopts full duplex communication of 1000BASE-T1 and therefore echo cancella-
tion on a single twisted-pair channel. This feature reduces cabling while preserving
the Ethernet MAC compatibility
