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. 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. Teledyne LeCroy's integration of trigger, decode and physical layer testing shortens FlexRay testing time.
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 Teledyne LeCroy's 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 timebase setting or the amount of zoom, the decode information is condensed or expanded to better assist in understanding events during short or long acquisitions. Various sections of the protocol are color-coded to make it easy to understand. Communication 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.
|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.|
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.
Eye Diagram Mask Testing
|Eye diagrams are an important part of testing many serial data standards and FlexRay is no different. Leveraging Teledyne 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 Teledyne 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. Teledyne LeCroy's statistical measurements with histograms, tracks and trends let you see how the channel behaves over time.
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
|Teledyne LeCroy offers the same powerful triggering and intuitive decoding capabilities for CAN, LIN, I2C, SPI, and UART signals. For complete embedded system testing the MS Series mixed signal oscilloscopes add 18 or 36 digital channels to the oscilloscope allowing you to look at all your analog, digital, and serial data waveforms simultaneously with complete analog/digital cross pattern triggering.|
