4. Tap "Source" and select the serial bus that is set to D-PHY (e.g. "SB1", unless
already selected).
5.
Specify search criteria according to Chapter 13.23.5.1, "D-PHY search setup",
on page 887
.
6. To acquire a waveform, press [Single].
The R&S RTO6 performs a D-PHY decode according to the thresholds and proto-
col settings of the associated serial bus source.
7. To start searching the acquired waveform for specific events, tap "Enable" in the
search setup dialog:
The R&S RTO6 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 442.

The M-PHY
®
is a serial communication protocol. Its specifications were developed by
the Mobile Industry Processor Interface (MIPI) alliance as standards for the communi-
cation of high-speed components, like smartphones and tablets, within mobile devices.
For more details on the specifications, refer to http://mipi.org/specifications/physical-
layer#M-PHY Specification.
This protocol is the foundation for several upper layer protocols, such as UniPro
SM
(Unified Protocol), which manage complex data transfer functions. Each of these proto-
cols is optimized for its particular purpose, such as data storage, data transfer, display,
camera, memory sharing and radio interface.
When implemented together with the MIPI UniPro, defined as UniPort-M, they deliver
high speed, low power, scalable and flexible data transport solutions.
The super speed inter-chip (SSIC) was developed by the USB standards committee
based on USB3.1 G1 (SuperSpeed). It is developed to support the chip to chip com-
munication of USB3 components. The lower communication layers are using M-PHY
as the encoder platform and use a multilane distribution similar to UniPro. The higher
communication layers (above 8b/10b) are almost identical to USB3.1 G1.
