Serial Data Debug Solutions Introduction
Overview
LeCroy's Serial Data Debug Solutions (SDDS) provide different Toolsets for analysis of the Supported Protocols.
Structure of This Manual
The documentation is structured in the following manner.

Introduction - This introduction explains the Toolsets.

Accessing Toolsets - Where you'll find the various toolsets on the interface/dialogs when the different
software options are enabled.

Using Toolsets - We then take you to the point of using the general parts of a given toolset - just up to the
point where protocol specific functions come into play.

Documentation for Each Supported Protocol - These remaining sections of the manual group the various
protocols into market-specific collections.
These collections include Encoding Schemes, General Purpose Embedded Protocols, Automotive and
Industrial Protocols, Audio Protocols, Military and Avionic Protocols, Handset and Cellular Protocols,
and Storage, Peripherals, and Interconnects.
Assumptions
A basic understanding of the various serial data standard physical and protocol layer specifications, and
knowledge of how these standards are used in embedded controllers is prerequisite. In addition, a basic
understanding of oscilloscope operation (specifically the LeCroy oscilloscope with which the serial trigger and
decode option is used) is required. Wherever practical or necessary, details on specific oscilloscope features
have been included in the material.
PLEASE NOTE THE FOLLOWING:

The Dialog Area (on page 196) topic covers essential input entry methods using standard LeCroy
oscilloscope interface controls and has been included in the Reference section at the end of this
documentation for convenience.

LeCroy has a policy of frequently updating software. While screen images in this manual may not exactly
match what is seen on your oscilloscope display, be assured that the functionality is nearly identical.

We are constantly expanding the coverage of serial data standards. Some capabilities covered in this
documentation may only be available with the latest version of our firmware at
www.lecroy.com .

Many of the capabilities described require updated versions of the firmware. If you are experiencing
trouble with your software option, please try updating your firmware version to 6.4.0.x or higher.
Toolsets and Supported Protocols
Serial Data Debug Solution Toolsets are integrated into the oscilloscope – no external hardware is used. Serial
data signals are input to the oscilloscope through normal passive or active probes, such as LeCroy’s ZS Series of
high impedance active probes or ZD Series of differential probes, or through the use of cable inputs.
Serial Data Debug Solution Toolsets include the following:

Decode (D) - Both D and TD Toolsets greatly increase your ability to debug and analyze embedded
controllers using serial bus communications. Protocols having only the D Toolset only have Serial Decode
functionality. The D Toolset provides algorithms that interpret and annotate protocol signals and simplify
data viewing and analysis. Trigger and Decode (TD) - Protocols having the TD Toolset have both Serial
Trigger and Decode capabilities. In addition to the Decode capabilities described above, the TD Toolset
also recognizes serial data patterns to trigger the oscilloscope at a pre-determined time; other signals
coincident with the desired serial data pattern can also be captured simultaneously.
