| Trigger Capability |
| Format |
Hexadecimal or Binary for Frame ID.
Decimal for Cycle Count |
| Trigger Setup |
Trigger on TSS (Start), Frame ID, Cycle Count, Symbols, and Errors |
| FRAME Setup |
Specify Frame ID(s) in Hexadecimal or Binary with condition of <=, <, =, >, >=, <>, IN RANGE, OUT OF RANGE, or DON’T CARE.
Specify Cycle Count from 0 to 63 with condition of <=, <, =, >, >=, <>, IN RANGE, OUT OF RANGE, or DON’T CARE. Specify Repetition Factor as 1, 2, 4, 8, 16, 32, or 64.
Specify various Frame Qualifiers (Payload Preamble, Null Frame, Sync Frame, and Startup Frame) as 0, 1, or X (don’t care). |
| DATA Setup |
Hexadecimal:
# Data Bytes = 0 to 8. Data can be defined by nibble.
Binary:
Any combination of 0,1, or X for 1-64 bits
Data pattern can be any length and can be set to start at any location in the up to 8 Byte / 64 bit sequence Error Setup Trigger on any combination of the following errors:
Frame Start Sequence (FSS) Error – triggers when the logic high time between the TSS and the first byte is too long. Byte Start Sequence
(BSS) Error – triggers anytime the BSS pattern is not seen between bytes where expected.
Frame End Sequence (FES) Error – triggers when the FS is not seen after the last byte.
Header CRC Error, Payload CRC Error (select Payload Channel A or B). |
| Symbol Trigger |
Trigger on any combination of the following:
Channel Idle Delimiter (CID) Symbol, Collision Avoidance Symbol (CAS) and/or Media Access Test Symbol (MTS), or Wakeup Pattern (WUP) |
| Bit Rates |
2.5, 5, or 10 Mb/s pre-defined nominal values, or user-defined nominal values in 1 Mb/s increments |
| Trigger Input |
Any analog Channel or the EXT input. |
| Decode + Search Capability |
| Format |
Hexadecimal, excepting Cycle Count (Decimal) |
| Decode Setup |
Threshold definition required for High and Low levels. Default is to Absolute (in volts) amplitude. Select Channel (A or B). |
| Decode Input |
Any analog Channel, Memory or Math trace, and any Digital trace |
| No of Decodes |
Up to 4 buses may be decoded at one time. In addition, zooms can be displayed (with decoded information) |
| Visual Aid |
Color Coding for FRAME, TSS, CID, FSS, Frame Qualifiers, Slot ID, Payload Length, Header CRC, Cycle Count, Data, BSS, Payload CRC and FES.
Decode information is intelligently annotated based on timebase setting, and overlaid on acquired waveform |
| Table Configure, Export Table |
Display 1 to 20 rows of decoded information for up to 4 different protocols or decodes in time order in a single table. Displayed information includes Index, Timestamp, and other various protocol-specific information. Table permits scrolling, touch to zoom, export to .csv file, and special display of long data or other patterns. |
| Pattern Search |
Search by Previous or Next Frame, Next ID (hexadecimal format), or Next Error Frame. |
| Model |
FLEXRAYbus TDMP only |
| Measure / Graph Capability |
| Serial Data Digital-to-Analog Conversion (DAC) |
Message to Value measurement parameter extracts and converts a specified portion of the data in an up to 2048 byte data/payload in the serial message and displays it as an analog decimal value. Supports different data encoding formats, message filtering to specific IDs, and complete re-scaling with unit conversion. Serial DAC Waveform plots the converted digital-to-analog data as a waveform time correlated to other acquisition data, and view the change in data over time. |
| Timing Measurements |
Message to Analog, Analog to Message, Message to Message, ΔMessage Time (identical message on same decoder), Time@Message (time from trigger). Serial Message may be defined by “ID =” (where applicable) and user-defined DATA with condition <=, <, =, >, >=, <>, IN RANGE, or OUT OF RANGE in any location in up to 2048 bits of data. Analog Signal may be defined by Slope (pos, neg), Level (abs or %) with Hysteresis setting. Holdoff may be set on the Analog Signal by either Time or Events (up to 1000) to preclude unwanted measurements. |
| Bus Status Measurements |
Number of Messages, Message Bit Rate, Message Bus Load %. Serial Message may be defined by “ID =” (where applicable) and user defined “DATA <=, <, =, >, >=, <>, in range, out of range” in any location in up to 2048 bits of data. |
| Eye Diagram Capability |
| Setup |
Create up to four simultaneous Eye Diagrams (one per Serial Decoder) of the physical layer signal(s). Eye Style selectable as color- or analog-persisted. Eye Saturation adjustable from 0 to 100%. |
| Eye Parameters |
FlexRay PHY: Supports SI Voting (ON or OFF). With SI Voting ON, with voting selection for Positive Bit Length, Negative Bit Length (or both), and Filtered Input is possible. With SI Voting OFF, Any combination of Propagation Delay, Asymmetric Delay, Frame TSS Length Change, or Jitter. Eye Diagram: Eye Height, Eye Width, (Number of) Mask Hits |
| Eye Mask |
Create a custom Mask using the free Teledyne LeCroy MaskMaker software utility. Store custom masks for later recall and use. Standard FlexRay TP1, TP1 Bus Driver, TP11, and TP11 Active Star are also provided. |
| Failure Indication and Location |
Mask Failure Indication ON or OFF (ON = indicated with a red circle).
Mask Failure Location trace waveform displayed and interactive with Eye Mask failure table. Supports STOP trigger on Mask Failure. |
