Features
The FlexRay Signal Analyzer DL7440/DL7480 meets various measurement and analysis needs.
| This high-performing unit, allows capture of FlexRay Bus Signals with Dedicated FlexRay Triggers. Capture the desired FlexRay bus signal by specifying combinations of trigger bit conditions of the Frame Start, Payload preamble, Null frame, Sync frame, Startup frame indicators, Frame ID, Cycle count and (Payload) Data. Triggers can also be activated on combinations of the FlexRay bus signal bit conditions and other analog signals, or CRC errors on the FlexRay bus. |

Simultaneous Display of Analysis Results, Corresponding Waveforms
| After signal capture, waveforms are displayed together with a list of analyzed frames. Frame waveforms can also be zoomed. Using 8 MW of internal memory, continuous bus waveforms of up to 80 ms can be captured at a sampling rate of 100 MS/s and analyzed. Since the frame waveform at the cursor in the list is automatically displayed, bus signals can be observed while the analysis results are viewed. The effect of noise and level fluctuations on the communication data can be easily determined for quick and efficient debugging. Analysis results can be saved to a file in text format. |  Analysis results list and waveform display

A Wealth of Powerful Auxiliary Functions to Support Analysis
| The detailed display mode allows the analyzed results to be displayed frame by frame, and show the time from the trigger point, each indicator bit, Frame ID, Payload length, Data, CRC, and Cycle count in relationship to the waveform. |  Detailed display mode
|
| The desired frame or segment can be located from within the captured data by searching using the Frame ID, Cycle Count, Sync frame, Data and CRC Error (with AND logic). When frames are found that match the search conditions, their signal waveforms are displayed in the zoom area. |

| The bit width can be displayed according to the bit rate with two cursors, and values can be checked while the cursor is moved by one or several bits at a time. In the right example , the area corresponding to the frame ID is shown using two cursors, and one bit width is indicated by the two dotted line cursors. |

Real-time analysis (for a single frame selected with a cursor)
Following each new waveform acquisition and display, the protocol analysis results for one frame are updated automatically. The frame is selected with a cursor and the following parameter items are measured and displayed in real time:

Time interval measurements between Byte Start Sequences (BSS)
| After the acquisition is complete, a specified time interval of the FlexRay bus signal such as the BSS-BSS interval or BSS-FES interval can be measured and the maximum, minimum, average, standard deviation and the number of measured values can also be calculated. The BSS-BSS interval can be between 1) every BSS in a frame, 2) every BSS in a selected frame 3) the first BSS in every frame, 4) the first BSS in a selected frame. For example, the time interval and the calculated statistical results between every frame (or specified frames) can be evaluated when the interval between the first BSS in different frames is measured. This function is useful for verifying whether there is time delay for a specified frame (data) over multiple cycles and also for verifying fluctuations of communication cycles. |
