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 100BASE-T1 (e.g. "SB1",
unless already selected).
The search dialog for 100BASE-T1 protocol analysis opens.
4. Specify search criteria according to Chapter 13.12.6, "Search on decoded
100BASE-T1 data", on page 724.
5. To acquire a waveform, press [RUN N× SINGLE].
The R&S RTE performs an 100BASE-T1 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.
13.13 SENT (option R&S RTE-K10)
Single Ended Nibble Transmission (SENT) is a serial transmission interface protocol
originally specified for the communication of sensors and control units in automotive
electronics.
SENT is a protocol standard governed by Society of Automotive Engineers (SAE
J2716). For detailed information, refer to the SENT standard specification on http://
www.sae.org.
The SENT protocol is used exclusively in automotive applications, as for example elec-
trical power steering, advanced driver assistance like parking assist or sensing of pres-
sure, throttle position, pedal position, airflow mass, liquid level, etc.
The R&S RTE option R&S RTE-K10 provides serial triggering, decoding and a highly
customizable search on decoded SENT signals.
13.13.1 The SENT protocol
This chapter provides an overview of the protocol characteristics, encoding scheme,
identifiers and trigger possibilities.
The SENT protocol transmits signal values point-to-point from a sensor to a controller
(electronic control unit ECU), unidirectional. In contrast to conventional measurements,
you can receive multiple data parameters via the SENT interface in a single transmis-
sion. Nevertheless, SENT is characterized by its simplicity and yet very high customiz-
ability to meet the individual requirements of the applications.
