WSXs-FLEXRAYBUS TD - Teledyne LeCroy

FlexRay™

Trigger, Decode

and Physical

Layer Test

The FlexRay™ trigger, decode and

physical layer test package adds a

unique set of tools to your oscilloscope

simplifying how you design and

debug your FlexRay systems and

shorten testing time. The powerful

internal FlexRay trigger quickly locates

speciﬁc IDs or messages and the

unique overlay shows decoded data

directly on top of the physical layer

signal. The eye diagram and timing

measurements quickly locate physical

layer problems.

Built-in Oscilloscope Trigger

Makes Setup Easy

Isolate speciﬁc FlexRay messages

with the built-in oscilloscope trigger.

Since the trigger is not a FlexRay

node, connection to your FlexRay bus

is simpliﬁed; and no re-programming

of the vehicle network is required,

simply connect a differential probe to

your FlexRay signal. All the triggering

is done in the oscilloscope and setup

is completely integrated into the

intuitive trigger menu.

The Most Intuitive Decode

Patented software algorithms

de construct the waveform into

protocol decode information, then

overlay the decoded data on the

waveform. Depending on the

time base setting or the amount

of zoom, the decode information is

condensed or expanded to better

assist in understanding events. Various

sections of the protocol are color-

coded to make it easy-to-understand.

Com mun i cation Cycle Start and Error

Frames are highlighted. The decode

operation is fast—even with long

acquisitions. The user can choose to

decode into Hex or Binary formats.

Powerful Physical Layer Test

Quickly locate physical layer problems

using powerful eye diagram mask

test, watch the eye build up over time

and use the error indicator to ﬁnd

mask violations and isolate problems.

Mask testing combined with the

built in automated FlexRay timing

measurements let you know how your

FlexRay physical layer is performing.

Trigger on Static or Dynamic Slot IDs and FlexRay Symbols, apply a color-coded, easy-to-

understand decode over your FlexRay signal, perform automatic eye diagram mask testing

and make physical layer timing measurements.

BROADEST OSCILLOSCOPE-BASED FLEXRAY SOLUTION

Extensive Triggering

Triggering on the complex FlexRay protocol

is made easy with an intuitive interface

and a wide range of trigger settings

for all aspects of the protocol. Set up a

simple TSS (Start) symbol trigger with a

single button press or trigger on any part

of a FlexRay frame including ID, Cycle

Count, Cycle Repetition Factor and Frame

Qualiﬁer. FlexRay deﬁned Symbols and

Errors can also be incorporated into the

trigger making it as simple or advanced

as necessary. Conditional triggering can

be set to trigger on a range of Frame IDs

or Cycles.

Eye Diagram Mask Testing

Eye diagrams are an important part

of testing many serial data standards

and FlexRay is no different. Leveraging

LeCroy’s techniques developed with

extremely fast serial data signals, the

FlexRay eye diagram mask test overlays

all the bits on FlexRay signal in an eye

diagram with pass/fail mask testing. Tell

the oscilloscope to stop on any mask

violation and quickly locate the source of

physical layer problems. By conﬁguring

the trigger for a speciﬁc Frame ID or

range of IDs an eye diagram can be

created to show only those Frames.

Gain valuable insight

into your FlexRay

communications

channel by viewing

eye diagrams,

physical layer

measurements and

decoded protocol

data at one time.

Physical Layer Measurements

Seeing the eye diagram gives good

insight to your FlexRay system but

measuring key timing parameters like

Propagation Delay, Asymmetric Delay,

Truncation and Jitter help you understand

how signals propagate along the channel.

Use LeCroy’s statistics and histicons to

understand the range of measurements

on the FlexRay channel.

Quickly measure channel properties

with measurement parameters

deﬁned by the FlexRay speciﬁcation.

LeCroy’s statistical measurements

with histograms, tracks and trends

let you see how the channel behaves

over time.

Trigger on every aspect of the FlexRay Frame as well as Symbols

and Errors including FSS, BSS, FES, CRC, CID, CAS/MTS and

Wakeup by selecting the appropriate boxes.

BROADEST OSCILLOSCOPE-BASED FLEXRAY SOLUTION

Convenient Table Display

Summarizes Results

Turn your oscilloscope into a protocol

analyzer with the Table display of

decoded information. Custom conﬁgure

the Table to display only the information

you want and export Table data to

an Excel ﬁle. Touch a message in the

table and automatically zoom for detail.

Display your values in an easy-to-understand table. Touch a row to zoom, or export to

Excel with one button push.

Search and Zoom

ID or Data values can be quickly

located by searching for a speciﬁc

value. In a long acquisition, pressing

NEXT advances the single byte

to the byte right or left of the

current message.

Search through

long record of

decoded data

by entering the

message or

address you are

looking for and

clicking the right or

left search arrows.

More Tools for Your Embedded

System Test

LeCroy offers the same powerful

triggering and intuitive decoding

capabilities for I2C, SPI, UART, RS-232,

Audiobus (I2S, LJ, RJ, TDM), CAN,

LIN, FlexRay,™ MIL-STD-1553)

signals. For complete embedded

system testing, the MS-250 and

MS-500 adds 18 or 36 digital channels

to the digital oscilloscope allowing you

to look at all your analog, digital, and

serial data waveforms simultaneously

with complete analog/digital cross

pattern triggering.
