MIPI CSI-3 Description and Features
Extend your oscilloscope’s capability with the
Keysight Technologies, Inc. CSI-3 protocol
decoder
Camera Serial Interface version 3.0 (CSI-3) standard was
developed by MIPI Alliance to increase performance throughput and greater feature set from CSI-2 standard. The CSI-3
interface runs on top of the MIPI M-PHY electrical layer as
well as the MIPI UniPro protocol layer that is also developed
by MIPI Alliance standard body. The serial bus interface
provides content-rich points for debug and test. However,
since this protocol transfers bits serially, using a traditional
oscilloscope has limitations. Manually converting captured
1’s and 0’s to protocol requires significant effort; can’t be
done in real-time; and includes potential for human error.
Also, traditional scope triggers are not sufficient for specifying
protocol-level conditions.
This application makes it easy to debug and test designs that
include CSI-3 buses using your Infiniium Series oscilloscope.
–– Set up your scope to show CSI-3 and UniPro protocol
decode in less than 30 seconds.
–– Get access to a rich set of integrated protocol-level triggers.
–– Save time and eliminate errors by viewing packets at the
protocol level.
–– Use time-correlated views to quickly troubleshoot serial
protocol problems back to their timing or signal integrity
root cause.

30-second CSI-3 setup
Configure your oscilloscope to display protocol
decode in under 30 seconds. Use “Auto Setup”
to automatically configure sample rate, memory
depth, threshold and trigger levels.
Support for live and saved waveforms
Perform and view decode information on both live
and saved waveforms. Decode up to any combination
of four live or saved waveforms or functions.

The following are the CSI-3 protocols and features that will
be supported by the application.
1. Support CSI-3 v1.0 decode and triggering
2. Can be used together with the N8808A MIPI UniPro
protocol decode to show both CSI-3 and UniPro packets
3. Decodes High-Speed (HS-BURST) and Low-Speed Pulse
Width Modulation (PWM-BURST) modes
4. Supports search capability for Host and Device
transactions as well as symbol sequence and errors.
MIPI CSI-3 Setup, Protocol Triggering and Search Capabilities
Get access to a rich set of integrated protocol-level triggers.
►
The application includes a suite of configurable protocol-level
trigger conditions specific to CSI-3. When serial triggering is
selected, the application uses software-based triggering.
With software-based protocol triggering, the oscilloscope
takes signals acquired using either oscilloscope or digital
channels and reconstructs protocol frames after each
acquisition.
It then inspects these protocol frames against specified
protocol-level trigger conditions and triggers when the
condition is met.
CSI-3 trigger and search setup
Quickly access the software-based trigger via the trigger or
search menus. Software-based triggering enables quick setup
of data, remote or error frames.

trigger conditions specific to CSI-3. When serial triggering is

With software-based protocol triggering, the oscilloscope

protocol frames after each acquisition. It then inspects these
protocol frames against specified protocol-level trigger
conditions and triggers when the condition is met.
Quickly move between physical and CSI-3 protocol layer information
using the time-correlated tracing marker. Display protocol content
using embedded decode in the waveform area, or see protocol
events in a compact listing format. Minor tick marks indicate
clock transitions. Major tick marks indicate segments of the serial
packet. CSI-3 measurements are automatically time-correlated with
measurement on other oscilloscope channels.
Compact protocol using the full screen listing
The protocol viewer window shows the index number, time stamp
value identifier, packet type, and data values for each CSI-3 packet.
Data in the listing window can be saved to a .csv or .txt file for off-line.
CSI-3 decode embedded in waveform area
Utilize the oscilloscope waveform area to display
decode information. Minor ticks indicate clock
transitions, and major ticks show segments within
each CSI-3 packet.
Long time captures using segmented memory
In this example, CSI-3 traffic was captured
for near 35 seconds. Segmented memory
uses time tags to track time between
segment acquisitions.
Using multiple oscilloscopes?
Server-based licensing allows
users to borrow an application
for a specified period of time.

CSI-3 Protocol Decode
Time correlation with other system activity
Protocol measurements are automatically time-correlated with
measurements taken on other analog or digital (on MSO models)
channels.
Post-acquisition searching
Search acquired protocol listings using a menu that is identical to
the trigger menu. Quickly move to next occurrence of a specified
event.
Precise MSO triggering and display
Mixed-signal oscilloscope measurement in a mobile system using
both digital and analog acquisition channels.
